Variable Interest Entities	3 Months Ended
Variable Interest Entities	Nov. 29, 2012
Disclosure Text Block [Abstract]
Variable Interest Entities	Variable Interest Entities We have interests in entities that are Variable Interest Entities ("VIEs"). If we are the primary beneficiary of a VIE, we are required to consolidate it. To determine if we are the primary beneficiary, we evaluate whether we have the power to direct the activities that most significantly impact the VIE's economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Our evaluation includes identification of significant activities and an assessment of our ability to direct those activities based on governance provisions and arrangements to provide or receive product and process technology, product supply, operations services, equity funding, financing and other applicable agreements and circumstances. Our assessments of whether we are the primary beneficiary of our VIEs require significant assumptions and judgment. Unconsolidated Variable Interest Entities Inotera: Inotera Memories, Inc. ("Inotera") is a VIE because (1) its equity is not sufficient to permit it to finance its activities without additional support from its shareholders and (2) of the terms of its supply agreement with us and Nanya Technology Corporation ("Nanya"). We have determined that we do not have the power to direct the activities of Inotera that most significantly impact its economic performance, primarily due to (1) limitations on our governance rights that require the consent of other parties for key operating decisions and (2) Inotera's dependence on Nanya for financing and the ability to operate in Taiwan. Therefore, we account for our interest in Inotera under the equity method. Transform: Transform Solar Pty Ltd. ("Transform") is a VIE because its equity is not sufficient to permit it to finance its activities without additional financial support from us or Origin Energy Limited ("Origin"). We have determined that we do not have the power to direct the activities of Transform that most significantly impact its economic performance, primarily due to limitations on our governance rights that require the consent of Origin for key operating decisions. Therefore, we account for our interest in Transform under the equity method. In May 2012, the Board of Directors of Transform approved a liquidation plan. As of August 30, 2012, Transform's operations were substantially discontinued. For further information regarding our VIEs that we account for under the equity method, see "Equity Method Investments" note. EQUVO Entities: EQUVO HK Limited and EQUVA Capital 1 Pte. Ltd. (together the "EQUVO Entities") are special purpose entities created to facilitate equipment sale-leaseback financing transactions between us and a consortium of financial institutions. Neither we nor the financial institutions have an equity interest in the EQUVO Entities. The EQUVO Entities are VIEs because their equity is not sufficient to permit them to finance their activities without additional support from the financial institutions and because the third-party equity holder lacks characteristics of a controlling financial interest. By design, the arrangement with the EQUVO Entities is merely a financing vehicle and we do not bear any significant risks from variable interests with the EQUVO Entities. Therefore, we have determined that we do not have the power to direct the activities of the EQUVO Entities that most significantly impact their economic performance and we do not consolidate the EQUVO Entities. Consolidated Variable Interest Entities IMFT: IM Flash Technologies, LLC ("IMFT") is a VIE because all of its costs are passed to us and its other member, Intel Corporation ("Intel"), through product purchase agreements and IMFT is dependent upon us or Intel for any additional cash requirements. We determined that we have the power to direct the activities of IMFT that most significantly impact its economic performance. The primary activities of IMFT are driven by the constant introduction of product and process technology. Because we perform a significant majority of the technology development, we have the power to direct its key activities. In addition, IMFT manufactures certain products exclusively for us using our technology. We also determined that we have the obligation to absorb losses and the right to receive benefits from IMFT that could potentially be significant to it. Therefore, we consolidate IMFT. MP Mask: MP Mask Technology Center, LLC ("MP Mask") is a VIE because all of its costs are passed to us and its other member, Photronics, Inc. ("Photronics"), through product purchase agreements and MP Mask is dependent upon us or Photronics for any additional cash requirements. We determined that we have the power to direct the activities of MP Mask that most significantly impact its economic performance, primarily because (1) of our tie-breaking voting rights over key operating decisions and (2) nearly all key MP Mask activities are driven by our supply needs. We also determined that we have the obligation to absorb losses and the right to receive benefits from MP Mask that could potentially be significant to it. Therefore, we consolidate MP Mask. For further information regarding our consolidated VIEs, see "Consolidated Variable Interest Entities" note.

- Definition

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.

Elpida Memory, Inc.	3 Months Ended
Elpida Memory, Inc.	Nov. 29, 2012
Elpida Memory, Inc. [Member]
Business Acquisition [Line Items]
Elpida Memory, Inc.	Elpida Memory, Inc. Elpida Sponsor Agreement On July 2, 2012, we entered into a sponsor agreement (the "Sponsor Agreement") with the trustees of Elpida Memory, Inc. ("Elpida") and its subsidiary, Akita Elpida Memory, Inc. ("Akita" and, together with Elpida, the "Elpida Companies"). The Elpida Companies filed petitions for corporate reorganization proceedings with the Tokyo District Court (the "Court") under the Corporate Reorganization Act of Japan on February 27, 2012. Under the Sponsor Agreement, we committed to support plans of reorganization for the Elpida Companies that would provide for payments to the secured and unsecured creditors of the Elpida Companies in an aggregate amount of 200 billion yen (or $2.44 billion, assuming approximately 82 yen per U.S. dollar, the exchange rate as of November 29, 2012), less certain expenses of the reorganization proceedings and certain other items. As a condition of the Sponsor Agreement, we deposited 1.8 billion yen (or $22 million) into an escrow account in July 2012 which will be applied to the share acquisition payments at closing. Of the aggregate amount, we will fund 60 billion yen (or $731 million) through a cash payment to Elpida at the closing, in exchange for 100% ownership of Elpida's equity. The remaining 140 billion yen (or $1.71 billion) of payments will be made by the Elpida Companies in six annual installments payable at the end of each calendar year beginning in 2014, with payments of 20 billion yen (or $244 million) in each of 2014 through 2017, and payments of 30 billion yen (or $365 million) in each of 2018 and 2019. We have agreed to provide additional financial support to Elpida, subject to certain conditions, which may include a payment guarantee under certain circumstances, to facilitate its continued access to working capital financing of up to 16 billion yen (or $195 million) from third-party finance sources through the closing of the Elpida share purchase, and to use reasonable efforts to assist Elpida in obtaining up to 5 billion yen (or $61 million) of continued working capital financing from third parties for up to two months following the closing. In addition, subject to certain conditions, we have agreed to use reasonable efforts to assist the Elpida Companies in financing up to 64 billion yen (or $780 million) of eligible capital expenditures incurred through June 30, 2014, including up to 40 billion yen (or $487 million) incurred prior to June 30, 2013, either by providing payment guarantees under certain circumstances, or by providing such financing directly. Failure to close the transaction would not relieve us of our obligations under any guarantees to third party financing sources entered into in connection with any such financing arrangements. As of November 29, 2012, we had provided a payment guarantee related to financing of capital expenditures of 29 million euros (or $38 million). In December 2012, we provided an additional payment guarantee related to financing of capital expenditures of 6 billion yen (or $73 million). Our obligations under these guarantee arrangements are collateralized by rights to certain equipment and other assets of Elpida. Under applicable Japanese law, following the closing of the transaction, because a portion of the payments to creditors will be satisfied through the installment payments described above, the operation of the businesses of the Elpida Companies will remain subject to the oversight of the Court in charge of the reorganization proceedings and of the trustees (including a trustee nominated by us upon the closing of the transaction). The Sponsor Agreement contains certain termination rights, including our right to terminate the Sponsor Agreement if a change, taken together with all other changes, occurs that is or would reasonably be expected to be materially adverse to (i) the business, assets, etc. of Elpida and its subsidiaries, taken as a whole, or to the business, assets, etc. taken as a whole of Rexchip Electronics Corporation ("Rexchip"), a Taiwanese corporation formed as a manufacturing joint venture by Elpida and Powerchip Technology Corporation ("Powerchip"), a Taiwanese corporation; or (ii) our ability to operate Elpida's business immediately following closing in substantially the same manner as conducted by Elpida as of July 2, 2012. Elpida currently owns, directly and indirectly through a subsidiary, approximately 65% of Rexchip's outstanding common stock. The trustees of the Elpida Companies submitted plans of reorganization to the Court on August 21, 2012, which plans are subject to court and creditor approval under applicable Japanese law. The Sponsor Agreement provides that the plans of reorganization submitted by the trustees are to contain terms consistent with the provisions of the Sponsor Agreement. Certain creditors of Elpida have challenged the proposed plan of reorganization submitted by the trustees and proposed an alternative plan of reorganization. On October 31, 2012, the Court approved submission of the plans of reorganization as submitted by the trustees of the Elpida Companies to creditors for approval. The Court also issued an order that the alternative plan of reorganization proposed by certain creditors of Elpida not be submitted to a creditor vote. The deadline for creditors to vote on the plans of reorganization is February 26, 2013. The consummation of the Sponsor Agreement is subject to various closing conditions, including but not limited to approval by the Court, requisite creditor approval, receipt of approvals in bankruptcy proceedings in other jurisdictions and receipt of regulatory approvals in other countries, including the People's Republic of China. The transaction is currently anticipated to close in the first half of calendar 2013. Rexchip Share Purchase Agreement On July 2, 2012, we entered into a share purchase agreement with Powerchip and certain of its affiliates (the "Rexchip Share Purchase Agreement"), under which we will purchase approximately 714 million shares of Rexchip common stock, which represents approximately 24% of Rexchip's outstanding common stock, for approximately 10 billion New Taiwan dollars (or $343 million, assuming approximately 29 New Taiwan dollars per U.S. dollar, the exchange rate as of November 29, 2012). The consummation of the Rexchip Share Purchase Agreement is subject to various closing conditions, including the closing of the transactions contemplated by the Sponsor Agreement. At the closing of the Sponsor Agreement and the Rexchip Share Purchase Agreement, our aggregate beneficial ownership interest in Rexchip will approximate 89%. Currency Hedging Elpida Hedges: On July 2, 2012, we executed a series of separate currency exchange transactions pursuant to which we purchased call options to buy 200 billion yen with a weighted-average strike price of 79.15 (yen per U.S. dollar). In addition, to reduce the cost of these call options, we sold put options to sell 100 billion yen with a strike price of 83.32 and we sold call options to buy 100 billion yen with a strike price of 75.57. The net cost of these call and put options, which expire on April 3, 2013, of $49 million is payable upon settlement. These currency options mitigate the risk of a strengthening yen for our yen-denominated payments under the Sponsor Agreement while preserving some ability for us to benefit if the value of the yen weakens relative to the U.S. dollar. These option contracts were not designated for hedge accounting and are remeasured at fair value each period with gains and losses reflected in our results of operations. As a result of the weaker yen since the inception of the hedge on July 2, 2012, the U.S. dollar equivalent of the 200 billion yen to be paid to the secured and unsecured creditors of the Elpida Companies decreased by $70 million as of November 29, 2012. As a result of the mark-to-market adjustments of the hedge, we have recorded cumulative losses in other operating expense of $53 million. Rexchip Hedges: On July 25, 2012, we executed a series of separate currency exchange transactions pursuant to which we purchased call options to buy 10 billion New Taiwan dollars with a weighted-average strike price of 29.21 (New Taiwan dollar per U.S. dollar). The cost of these options, which expire on April 2, 2013, of $3 million is payable upon settlement. These currency options mitigate the risk of a strengthening New Taiwan dollar for our payments under the Rexchip Share Purchase Agreement. These option contracts were not designated for hedge accounting and are remeasured at fair value each period with gains and losses reflected in our results of operations.

Inotera	$	326	39.7	%	$	370	39.7	%

We recognize our share of earnings or losses from these entities under the equity method, generally on a two-month lag. Equity in net loss of equity method investees, net of tax, included the following:



Quarter ended	November 29, 2012			December 1, 2011
Inotera	$	(53	)	$	(63	)
Other	1			(11		)
	$	(52	)	$	(74	)

Our maximum exposure to loss from our involvement with our equity method investments that were VIEs was $276 million and primarily included our Inotera investment balance as well as related translation adjustments in accumulated other comprehensive income and receivables, if any. We may also incur losses in connection with our rights and obligations to purchase a portion of Inotera's wafer production capacity under a supply agreement with Inotera.

Inotera

We have partnered with Nanya in Inotera, a Taiwanese DRAM memory company, since the first quarter of 2009. As of November 29, 2012, we held a 39.7% ownership interest in Inotera, Nanya held a 26.3% ownership interest and the remaining ownership interest was publicly held.

The net carrying value of our initial and subsequent investments was less than our proportionate share of Inotera's equity at the time of those investments. These differences are being amortized as a net credit to earnings through equity in net loss of equity method investees (the "Inotera Amortization"). In the first quarter of 2012, we recognized $12 million of Inotera Amortization and as of August 30, 2012, the remaining amount of unrecognized Inotera Amortization was not significant.

Due to significant market declines in the selling prices of DRAM, Inotera incurred net losses of $410 million for its nine-month period ended September 30, 2012 and $737 million for its fiscal year ended December 31, 2011. Also, Inotera's current liabilities exceeded its current assets by $1.8 billion as of September 30, 2012, which exposes Inotera to liquidity risk. As of June 30, 2012, Inotera was not in compliance with certain loan covenants, and had not been in compliance for the past several years. Inotera received a waiver from complying with the June 30, 2012 financial covenants. Inotera's management has developed plans to improve its liquidity, but there can be no assurance that Inotera will be successful in improving its liquidity, which may result in its lenders requiring repayment of such loans during the next year.

As of November 29, 2012, based on the closing trading price of Inotera's shares in an active market, the market value of our equity interest in Inotera was $167 million, which was below our net carrying value of $270 million. The net carrying value is our investment balance less cumulative translation adjustments in accumulated other comprehensive income (loss). As of November 29, 2012 and August 30, 2012, there were gains of $56 million and $49 million, respectively, in accumulated other comprehensive income (loss) for cumulative translation adjustments from our equity investment in Inotera. We evaluated our investment in Inotera and concluded that the decline in the market value below carrying value was not an other-than-temporary-impairment for a number of reasons including: (1) the market value increased above our carrying value subsequent to the end of the first quarter of 2013 and (2) the difference between market value and carrying value existed for less than two months.

We have a supply agreement with Inotera, under which Nanya is also a party, for the rights and obligations to purchase 50% of Inotera's wafer production capacity (the "Inotera Supply Agreement"). We have rights to receive a higher share of Inotera's 30-nanometer output when it becomes available. Our cost of wafers purchased under the Inotera Supply Agreement is based on a margin-sharing formula among Nanya, Inotera and us. Under such formula, all parties' manufacturing costs related to wafers supplied by Inotera, as well as our and Nanya's revenue for the resale of products from wafers supplied by Inotera, are considered in determining costs for wafers acquired from Inotera. Under the Inotera Supply Agreement, we purchased $201 million and $156 million of DRAM products in the first quarters of 2013 and 2012, respectively. In the first quarter of 2012, we recognized losses on our purchase commitment under the Inotera Supply Agreement of $40 million.

Under a cost-sharing arrangement, we generally share DRAM development costs with Nanya. As a result of the cost-sharing arrangement, our research and development ("R&D") costs were reduced by $15 million and $37 million in the first quarters of 2013 and 2012, respectively. In addition, we recognized royalty revenue from Nanya of $2 million and $3 million in the first quarters of 2013 and 2012, respectively, for sales of DRAM products manufactured by or for Nanya on process nodes of 50nm or higher.

We are currently in discussions with Nanya and Inotera regarding potential changes to our agreements. Such potential changes may include us receiving a significantly higher share of Inotera's output than our current share and an adjustment to the pricing formula. Additionally, our share of DRAM R&D costs may increase.

Other

Transform: In the second quarter of 2010, we acquired a 50% interest in Transform, a developer, manufacturer and marketer of photovoltaic technology and solar panels, from Origin. As of November 29, 2012, we and Origin each held a 50% ownership interest in Transform. As a result of the ongoing challenging global environment in the solar industry and unfavorable worldwide supply and demand conditions, in May 2012 the Board of Directors of Transform approved a liquidation plan. As of August 30, 2012, Transform's operations were substantially discontinued.

Aptina: Other equity method investments included a 30.2% equity interest in Aptina. The amount of cumulative loss we recognized from our investment in Aptina through the second quarter of 2012 reduced our investment balance to zero and we ceased recognizing our proportionate share of Aptina's losses.

We manufacture components for CMOS image sensors for Aptina under a wafer supply agreement. For the first quarters of 2013 and 2012, we recognized net sales of $61 million and $94 million, respectively, from products sold to Aptina, and cost of goods sold of $81 million and $94 million, respectively.

- Definition

The entire disclosure for equity method investments and joint ventures. Equity method investments are investments that give the investor the ability to exercise significant influence over the operating and financial policies of an investee.

Subject to customary conditions, we can draw up to $214 million under the facility agreement prior to April 4, 2013. Amounts drawn are payable in 10 equal semi-annual installments beginning six months after the draw date. On October 18, 2012, we drew $173 million with interest at 2.4% per annum. Additional amounts drawn will bear interest, at our option, at either (i) a fixed rate negotiated at the time of the draw request or (ii) a floating rate equal to the six-month LIBOR rate plus 1.6% per annum. The facility agreement contains customary covenants.

Revolving Credit Facility

On September 5, 2012, we entered into a three-year revolving credit facility. Under this credit facility, we can draw up to the lesser of $255 million or 80% of the net outstanding balance of a pool of certain trade receivables. We granted a security interest in such receivables to collateralize the facility. The availability of the facility is subject to certain customary conditions, including the absence of any event or circumstance that has a material adverse effect on our business or financial condition. Interest is payable monthly on any outstanding principal balance at a variable rate equal to the 30-day Singapore Interbank Offering Rate ("SIBOR") plus 2.8% per annum. As of November 29, 2012, we had not drawn any amounts under this facility.

Disclosure Text Block [Abstract]
Contingencies	Contingencies We have accrued a liability and charged operations for the estimated costs of adjudication or settlement of various asserted and unasserted claims existing as of the balance sheet date, including those described below. We are currently a party to other legal actions arising from the normal course of business, none of which is expected to have a material adverse effect on our business, results of operations or financial condition. Patent Matters As is typical in the semiconductor and other high technology industries, from time to time, others have asserted, and may in the future assert, that our products or manufacturing processes infringe their intellectual property rights. We are engaged in litigation with Rambus, Inc. ("Rambus") relating to certain of Rambus' patents and certain of our claims and defenses. Our lawsuits with Rambus are pending in the U.S. District Court for the District of Delaware, U.S. District Court for the Northern District of California, Germany, France, and Italy. On August 28, 2000, we filed a complaint against Rambus in the U.S. District Court for the District of Delaware seeking declaratory and injunctive relief. The complaint alleges, among other things, various anticompetitive activities and also seeks a declaratory judgment that certain Rambus patents are invalid and/or unenforceable. Rambus subsequently filed an answer and counterclaim in Delaware alleging, among other things, infringement of twelve Rambus patents and seeking monetary damages and injunctive relief. We subsequently added claims and defenses based on Rambus' alleged spoliation of evidence and litigation misconduct. The spoliation and litigation misconduct claims and defenses were heard in a bench trial before Judge Robinson in October 2007. On January 9, 2009, Judge Robinson entered an opinion in our favor holding that Rambus had engaged in spoliation and that the twelve Rambus patents in the suit were unenforceable against us. Rambus subsequently appealed the decision to the U.S. Court of Appeals for the Federal Circuit. On May 13, 2011, the Federal Circuit affirmed Judge Robinson's finding of spoliation, but vacated the dismissal sanction and remanded the case to the Delaware District Court for analysis of the remedy based on the Federal Circuit's decision. On January 2, 2013, Judge Robinson entered a new opinion in our favor holding that Rambus had engaged in spoliation, that Rambus' spoliation was done in bad faith, that the spoliation prejudiced us, and that the appropriate sanction was to declare the twelve Rambus patents in the suit unenforceable against us. On January 13, 2006, Rambus filed a lawsuit against us in the U.S. District Court for the Northern District of California alleging that certain of our DDR2, DDR3, RLDRAM and RLDRAM II products infringe as many as fourteen Rambus patents and seeking monetary damages, treble damages, and injunctive relief. The Northern District of California Court stayed the trial of the patent phase of the Northern District of California case upon appeal of the Delaware spoliation issue to the Federal Circuit. On September 1, 2011, HSM Portfolio LLC and Technology Properties Limited LLC filed a patent infringement action in the U.S. District Court for the District of Delaware against us and seventeen other defendants. The complaint alleges that certain of our DRAM and image sensor products infringe two U.S. patents and seeks injunctive relief, damages, attorneys' fees, and costs. On September 9, 2011, Advanced Data Access LLC filed a patent infringement action in the U.S. District Court for the Eastern District of Texas (Tyler) against us and seven other defendants. On November 16, 2011, Advanced Data Access filed an amended complaint. The amended complaint alleges that certain of our DRAM products infringe two U.S. patents and seeks injunctive relief, damages, attorneys' fees, and costs. On September 14, 2011, Smart Memory Solutions LLC filed a patent infringement action in the U.S. District Court for the District of Delaware against us and Winbond Electronics Corporation of America. The complaint alleges that certain of our NOR Flash products infringe a single U.S. patent and seeks injunctive relief, damages, attorneys' fees, and costs. On December 5, 2011, the Board of Trustees for the University of Illinois filed a patent infringement action against us in the U.S. District Court for the Central District of Illinois. The complaint alleges that unspecified semiconductor products of ours infringe three U.S. patents and seeks injunctive relief, damages, attorneys' fees, and costs. We have filed three petitions for inter-partes review by the Patent and Trademark Office, challenging the validity of each of the patents in suit. The District Court has stayed the litigation pending the outcome of the inter-partes review by the Patent Office. On March 26, 2012, Semiconductor Technologies, LLC filed a patent infringement action in the U.S. District Court for the Eastern District of Texas (Marshall) against us. The complaint alleges that certain of our DRAM products infringe five U.S. patents and seeks injunctive relief, damages, attorneys' fees, and costs. On April 27, 2012, Semcon Tech, LLC filed a patent infringement action against us in the U.S. District Court for the District of Delaware. The complaint alleges that our use of various chemical mechanical planarization systems purchased from Applied Materials and others infringes a single U.S. patent and seeks injunctive relief, damages, attorneys' fees, and costs. Among other things, the above lawsuits pertain to certain of our SDRAM, DDR, DDR2, DDR3, RLDRAM, NAND Flash, NOR Flash and image sensor products, which account for a significant portion of our net sales. We are unable to predict the outcome of assertions of infringement made against us and therefore cannot estimate the range of possible loss. A court determination that our products or manufacturing processes infringe the intellectual property rights of others could result in significant liability and/or require us to make material changes to our products and/or manufacturing processes. Any of the foregoing could have a material adverse effect on our business, results of operations or financial condition. Antitrust Matters On May 5, 2004, Rambus filed a complaint in the Superior Court of the State of California (San Francisco County) against us and other DRAM suppliers which alleged that the defendants harmed Rambus by engaging in concerted and unlawful efforts affecting Rambus DRAM by eliminating competition and stifling innovation in the market for computer memory technology and computer memory chips. Rambus' complaint alleged various causes of action under California state law including, among other things, a conspiracy to restrict output and fix prices, a conspiracy to monopolize, intentional interference with prospective economic advantage, and unfair competition. Rambus sought a judgment for damages of approximately $3.9 billion, joint and several liability, trebling of damages awarded, punitive damages, a permanent injunction enjoining the defendants from the conduct alleged in the complaint, interest, and attorneys' fees and costs. Trial began on June 20, 2011, and the case went to the jury on September 21, 2011. On November 16, 2011, the jury found for us on all claims. On April 2, 2012, Rambus filed a notice of appeal to the California 1st District Court of Appeal. At least sixty-eight purported class action price-fixing lawsuits have been filed against us and other DRAM suppliers in various federal and state courts in the United States and in Puerto Rico on behalf of indirect purchasers alleging a conspiracy to increase DRAM prices in violation of federal and state antitrust laws and state unfair competition law, and/or unjust enrichment relating to the sale and pricing of DRAM products during the period from April 1999 through at least June 2002. The complaints seek joint and several damages, trebled, in addition to restitution, costs and attorneys' fees. A number of these cases have been removed to federal court and transferred to the U.S. District Court for the Northern District of California for consolidated pre-trial proceedings. In July, 2006, the Attorneys General for approximately forty U.S. states and territories filed suit in the U.S. District Court for the Northern District of California. The complaints allege, among other things, violations of the Sherman Act, Cartwright Act, and certain other states' consumer protection and antitrust laws and seek joint and several damages, trebled, as well as injunctive and other relief. On October 3, 2008, the California Attorney General filed a similar lawsuit in California Superior Court, purportedly on behalf of local California government entities, alleging, among other things, violations of the Cartwright Act and state unfair competition law. On June 23, 2010, we executed a settlement agreement resolving these purported class-action indirect purchaser cases and the pending cases of the Attorneys General relating to alleged DRAM price-fixing in the United States. Subject to certain conditions, including final court approval of the class settlements, we agreed to pay approximately $67 million in aggregate in three equal installments over a two-year period. As of November 29, 2012, we had paid the full amount into an escrow account in accordance with the settlement agreement. Three putative class action lawsuits alleging price-fixing of DRAM products also have been filed against us in Quebec, Ontario, and British Columbia, Canada, on behalf of direct and indirect purchasers, asserting violations of the Canadian Competition Act and other common law claims (collectively the "Canadian Cases"). The claims were initiated between December 2004 (British Columbia) and June 2006 (Quebec). The plaintiffs seek monetary damages, restitution, costs, and attorneys' fees. The substantive allegations in these cases are similar to those asserted in the DRAM antitrust cases filed in the United States. Plaintiffs' motion for class certification was denied in the British Columbia and Quebec cases in May and June 2008, respectively. Plaintiffs subsequently filed an appeal of each of those decisions. On November 12, 2009, the British Columbia Court of Appeal reversed, and on November 16, 2011, the Quebec Court of Appeal also reversed the denial of class certification and remanded the cases for further proceedings. On October 16, 2012, we entered into a settlement agreement resolving these three putative class action cases subject to certain conditions including final court approval of the settlement. The settlement amount did not have a material effect on our business, results of operations or financial condition. On June 21, 2010, the Brazil Secretariat of Economic Law of the Ministry of Justice ("SDE") announced that it had initiated an investigation relating to alleged anticompetitive activities within the DRAM industry. The SDE's Notice of Investigation names various DRAM manufacturers and certain executives, including us, and focuses on the period from July 1998 to June 2002. We are unable to predict the outcome of these matters and therefore cannot estimate the range of possible loss, except as noted in the U.S. indirect purchaser cases and the Canadian Cases above. The final resolution of these alleged violations of antitrust laws could result in significant liability and could have a material adverse effect on our business, results of operations or financial condition. Commercial Matters On January 20, 2011, Dr. Michael Jaffé, administrator for Qimonda AG ("Qimonda") insolvency proceedings, filed suit against us and Micron Semiconductor B.V., our Netherlands subsidiary, in the District Court of Munich, Civil Chamber. The complaint seeks to void under Section 133 of the German Insolvency Act a share purchase agreement between us and Qimonda signed in fall 2008 pursuant to which we purchased all of Qimonda's shares of Inotera Memories, Inc. and seeks an order requiring us to retransfer the Inotera shares purchased from Qimonda to the Qimonda estate. The complaint also seeks to terminate under Sections 103 or 133 of the German Insolvency Code a patent cross license between us and Qimonda entered into at the same time as the share purchase agreement. A three-judge panel will render a decision after a series of hearings with pleadings, arguments and witnesses. A first hearing was held on September 25, 2012. The next hearing is scheduled for February 5, 2013. We are unable to predict the outcome of this lawsuit and therefore cannot estimate the range of possible loss. The final resolution of this lawsuit could result in the loss of the Inotera shares or equivalent monetary damages and the termination of the patent cross license, which could have a material adverse effect on our business, results of operation or financial condition. As of November 29, 2012, the Inotera shares purchased from Qimonda had a net carrying value of $149 million. Other In the normal course of business, we are a party to a variety of agreements pursuant to which we may be obligated to indemnify the other party. It is not possible to predict the maximum potential amount of future payments under these types of agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. Historically, our payments under these types of agreements have not had a material adverse effect on our business, results of operations or financial condition. Under the Sponsor Agreement, we have provided payment guarantees related to financing of capital expenditures. (See "Elpida Memory, Inc." note.)

Derivative Financial Instruments

3 Months Ended

Nov. 29, 2012

Disclosure Text Block [Abstract]

Derivative Financial Instruments

We are exposed to currency exchange rate risk for monetary assets and liabilities held or denominated in foreign currencies, primarily the euro, shekel, Singapore dollar and yen. We are also exposed to currency exchange rate risk for capital expenditures and operating cash flows, primarily denominated in the euro and yen. In connection with the Sponsor Agreement and Rexchip Share Purchase Agreement entered into in July 2012, we are exposed to significant currency exchange rate risk for the yen and New Taiwan dollar. We use derivative instruments to manage our exposures to changes in currency exchange rates. For exposures associated with our monetary assets and liabilities, our primary objective in entering into currency derivatives is to reduce the volatility that changes in currency exchange rates have on our earnings. For exposures associated with our capital expenditures and operating cash flows, our primary objective in entering into currency derivatives is to reduce the volatility that changes in currency exchange rates have on future cash flows. For exposures associated with our yen or New Taiwan dollar denominated payment obligations under the Sponsor Agreement and Rexchip Share Purchase Agreement, our primary objective for entering into currency derivatives is to mitigate risks if those currencies strengthen relative to the U.S. dollar, while preserving some ability for us to benefit if those currencies weaken.

Our derivatives consist primarily of currency forward contracts and currency options. The derivatives expose us to credit risk to the extent the counterparties may be unable to meet the terms of the derivative instrument. As of November 29, 2012, our maximum exposure to loss due to credit risk if counterparties fail completely to perform according to the terms of the contracts, was equal to the fair value of our assets for these contracts as listed in the tables below. We seek to mitigate such risk by limiting our counterparties to major financial institutions and by spreading risk across multiple major financial institutions. In addition, we monitor the potential risk of loss with any one counterparty resulting from this type of credit risk on an ongoing basis. We have the following currency risk management programs:

Currency Derivatives without Hedge Accounting Designation

We utilize a rolling hedge strategy with currency forward contracts that generally mature within 35 days to hedge our exposure to changes in currency exchange rates from our monetary assets and liabilities. At the end of each reporting period, monetary assets and liabilities held or denominated in currencies other than the U.S. dollar are remeasured in U.S. dollars and the associated outstanding forward contracts are marked-to-market. Currency forward contracts are valued at fair values based on the middle of bid and ask prices of dealers or exchange quotations (referred to as Level 2). Realized and unrealized gains and losses on derivative instruments and the underlying monetary assets and liabilities are included in other operating (income) expense.

In connection with the currency exchange rate risk with the Sponsor Agreement and Rexchip Share Purchase Agreement, we entered into currency options that expire on April 3, 2013 and April 2, 2013, respectively. Currency options are valued at their fair value using a modified Black-Scholes option valuation model using inputs of the current spot rate, strike price, risk-free interest rate, time to maturity, volatility and credit-risk spread (referred to as Level 2). These options are marked-to-market at the end of each reporting period and realized and unrealized gains and losses are included in other operating (income) expense.

Total gross notional amounts and fair values for currency derivatives without hedge accounting designation were as follows:

For currency forward contracts and options without hedge accounting designation, we recognized net losses of $51 million and $20 million for the first quarters of 2013 and 2012, respectively, which were included in other operating (income) expense.

Currency Derivatives with Cash Flow Hedge Accounting Designation

We utilize currency forward contracts that generally mature within 12 months and currency options that generally mature from 12 to 18 months to hedge our exposure to changes in cash flows from changes in currency exchange rates for certain capital expenditures and forecasted operating cash flows. Currency forward contracts are valued at their fair values based on market-based observable inputs including currency exchange spot and forward rates, interest rate and credit risk spread (referred to as Level 2). Currency options are valued at their fair value using a modified Black-Scholes option valuation model using inputs of the current spot rate, strike price, risk-free interest rate, time to maturity, volatility and credit-risk spread (referred to as Level 2). For derivatives designated as cash flow hedges, the effective portion of the realized and unrealized gain or loss on the derivatives was included as a component of accumulated other comprehensive income (loss). For derivatives hedging capital expenditures, the amounts in accumulated other comprehensive income (loss) for these cash flow hedges are reclassified into earnings in the same line items of the consolidated statements of operation and in the same periods in which the underlying transactions affect earnings. Amounts in accumulated other comprehensive income (loss) for inventory purchases are reclassified to earnings when inventory is sold. The ineffective or excluded portion of the realized and unrealized gain or loss is included in other operating (income) expense. Total gross notional amounts and fair values for currency derivatives with cash flow hedge accounting designation were as follows:



	Notional Amount (in U.S. Dollars)		Fair Value of
Currency	Notional Amount (in U.S. Dollars)		Asset⁽¹⁾		(Liability)⁽²⁾

For the first quarters of 2013 and 2012, we recognized net pre-tax derivative losses of $4 million and $9 million, respectively, in accumulated other comprehensive income (loss) from the effective portion of cash flow hedges. The ineffective and excluded portions of cash flow hedges recognized in other operating (income) expense were not significant in the first quarters of 2013 and 2012. In the first quarters of 2013 and 2012, $3 million and $2 million, respectively, of pre-tax net gains were reclassified from accumulated other comprehensive income (loss) to earnings. As of November 29, 2012, the amount of pre-tax net derivative gains included in accumulated other accumulated comprehensive income (loss) expected to be reclassified into earnings in the next 12 months was $6 million.

Fair Value Measurements

3 Months Ended

Nov. 29, 2012

Disclosure Text Block [Abstract]

Fair Value Measurements

Accounting standards establish three levels of inputs that may be used to measure fair value: quoted prices in active markets for identical assets or liabilities (referred to as Level 1), inputs other than Level 1 that are observable for the asset or liability either directly or indirectly (referred to as Level 2) and unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities (referred to as Level 3).

Fair Value Measurements on a Recurring Basis

All marketable debt and equity investments are classified as available-for-sale and are carried at fair value. Assets measured at fair value on a recurring basis were as follows:



As of	November 29, 2012								August 30, 2012
	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total
Cash equivalents:

Noncurrent assets:
Assets held for sale	—		—		25		25		—		—		25		25

	$	1,739	$	800	$	25	$	2,564	$	2,164	$	530	$	25	$	2,719

Government securities consist of securities issued directly by or deemed to be guaranteed by government entities such as U.S. and non-U.S. agency securities, government bonds and treasury securities. Level 2 securities are valued using information obtained from pricing services, which obtain quoted market prices for similar instruments, non-binding market consensus prices that are corroborated by observable market data, or various other methodologies, to determine the appropriate value at the measurement date. We perform supplemental analysis to validate information obtained from our pricing services. As of November 29, 2012, no adjustments were made to such pricing information.

Level 3 assets consisted primarily of semiconductor equipment and facilities classified as held for sale. Fair value for semiconductor equipment was based on quotations obtained from equipment dealers, which consider the remaining useful life and configuration of the equipment. Fair value for facilities was determined based on sales of similar facilities and properties in comparable markets. Losses recognized in the first quarters of 2013 and 2012 due to fair value measurements using Level 3 inputs were not significant. For the first quarters of 2013 and 2012, activity of assets held for sale was not significant.

Fair Value of Financial Instruments

Amounts reported as cash and equivalents, receivables, and accounts payable and accrued expenses approximate fair value. The estimated fair value and carrying value of debt instruments (carrying value excludes the equity components of our convertible notes classified in equity) were as follows:



As of	November 29, 2012				August 30, 2012
	Fair Value		Carrying Value		Fair Value		Carrying Value
Convertible notes	$	2,638	$	2,345	$	2,669	$	2,321
Other notes	214		222		56		58

The fair value of our convertible debt instruments was determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, including our stock price and interest rates based on similar debt issued by parties with credit ratings similar to ours (Level 2). The fair value of our other debt instruments was estimated based on discounted cash flows using inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, including interest rates based on similar debt issued by parties with credit ratings similar to ours (Level 2).

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

As of November 29, 2012, we had an aggregate of 160.3 million shares of common stock reserved for the issuance of stock options and restricted stock awards, of which 99.4 million shares were subject to outstanding awards and 60.9 million shares were available for future awards. Awards are subject to terms and conditions as determined by our Board of Directors.

Stock Options

We granted 3.9 million and 5.9 million stock options during the first quarters of 2013 and 2012, respectively, with weighted-average grant-date fair values per share of $2.99 and $2.95, respectively.

The fair values of option awards were estimated at each grant date using the Black-Scholes option valuation model. The Black-Scholes model requires the input of assumptions, including the expected stock price volatility and estimated option life. The expected volatilities utilized were based on implied volatilities from traded options on our stock and on historical volatility. The expected lives of options granted were based, in part, on historical experience and on the terms and conditions of the options. The risk-free interest rates utilized were based on the U.S. Treasury yield in effect at each grant date. No dividends were assumed in estimated option values. Assumptions used in the Black-Scholes model are presented below:



Quarter ended	November 29, 2012		December 1, 2011
Average expected life in years	5.0		5.1
Weighted-average expected volatility	62	%	67	%
Weighted-average risk-free interest rate	0.7	%	1.1	%

Restricted Stock and Restricted Stock Units ("Restricted Stock Awards")

As of November 29, 2012, there were 11.5 million shares of Restricted Stock Awards outstanding, of which 3.5 million were performance-based Restricted Stock Awards. For service-based Restricted Stock Awards, restrictions generally lapse in one-fourth increments during each year of employment after the grant date. For performance-based Restricted Stock Awards, vesting is contingent upon meeting certain performance goals. Restricted Stock Awards granted for the first quarter of 2013 and 2012 were as follows:



Quarter ended	November 29, 2012		December 1, 2011
Service-based awards	2.2		1.8
Performance-based awards	1.2		1.9
Weighted-average grant-date fair values per share	$	5.73	$	5.17

Stock-based Compensation Expense

Total compensation costs for our equity plans were as follows:



Quarter ended	November 29, 2012		December 1, 2011
Stock-based compensation expense by caption:
Cost of goods sold	$	6	$	5
Selling, general and administrative	9		11
Research and development	4		4
	$	19	$	20

Stock-based compensation expense by type of award:
Stock options	$	13	$	12
Restricted stock awards	6		8
	$	19	$	20

As of November 29, 2012, $149 million of total unrecognized compensation costs, net of estimated forfeitures, related to non-vested awards was expected to be recognized through the first quarter of 2017, resulting in a weighted-average period of 1.2 years. Stock-based compensation expense in the above presentation does not reflect any significant income tax benefits, which is consistent with our treatment of income or loss from our U.S. operations. (See "Income Taxes" note.)

- Definition

The entire disclosure for compensation-related costs for equity-based compensation, which may include disclosure of policies, compensation plan details, allocation of equity compensation, incentive distributions, equity-based arrangements to obtain goods and services, deferred compensation arrangements, employee stock ownership plan details and employee stock purchase plan details.

Disclosure Text Block [Abstract]
Income Taxes	Income Taxes Income taxes for the first quarter of 2012 included a tax benefit of $14 million related to the favorable resolution of certain prior year tax matters, which was previously reserved as an uncertain tax position. Remaining taxes for the first quarters of 2013 and 2012 primarily reflect taxes on our non-U.S. operations. We have a valuation allowance for our net deferred tax asset associated with our U.S. operations. The provision (benefit) for taxes on U.S. operations in the first quarters of 2013 and 2012 was substantially offset by changes in the valuation allowance. We currently operate in several tax jurisdictions where we have arrangements that allow us to compute our tax provision at rates below the local statutory rates that expire in whole or in part at various dates through 2026. These arrangements benefitted our tax provision in the first quarter of 2013 by $11 million ($0.01 per diluted share) and were not significant in the first quarter of 2012.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Earnings Per Share

3 Months Ended

Disclosure Text Block [Abstract]

Earnings Per Share

Basic earnings per share is computed based on the weighted-average number of common shares and stock rights outstanding. Diluted earnings per share is computed based on the weighted-average number of common shares and stock rights outstanding plus the dilutive effects of equity awards and convertible notes. Potential common shares that would increase earnings per share amounts or decrease loss per share amounts are antidilutive and are therefore excluded from diluted earnings per share calculations. Antidilutive potential common shares that could dilute basic earnings per share in the future were 356.8 million and 285.5 million for the first quarters of 2013 and 2012, respectively.

Consolidated Variable Interest Entities

IM Flash

IMFT: Since its inception in 2006 through November 29, 2012, we have owned 51% of IMFT, a venture between us and Intel, to manufacture NAND Flash memory products and, since the third quarter of 2012, certain emerging memory technologies, for the exclusive use of the members. IMFT is governed by a Board of Managers and the number of managers appointed by each member to the board varies based on the members' respective ownership interests, which is based on contributions to IMFT. The IMFT joint venture agreement extends through 2024 and includes certain buy-sell rights, commencing in 2015, pursuant to which Intel may elect to sell to us, or we may elect to purchase from Intel, Intel's interest in IMFT. If Intel elects to sell, we would set the closing date of the transaction within two years following such election and could elect to receive financing of the purchase price from Intel for one to two years from the closing date.

The following table presents the assets and liabilities of IMFT included in our consolidated balance sheets, excluding intercompany balances:



As of	November 29, 2012		August 30, 2012
Assets
Cash and equivalents	$	56	$	157
Receivables	66		78
Inventories	62		67

Total liabilities	$	245	$	325

Our ability to access IMFT's cash and investments to finance our other operations is subject to agreement by Intel. Creditors of IMFT have recourse only to its assets and do not have recourse to any other of our assets.

IMFT manufactures NAND Flash memory products using designs and technology we develop with Intel. We generally share with Intel the cost of product design, other NAND Flash R&D costs and, since the third quarter of 2012, the R&D cost of certain emerging memory technologies. Our R&D expenses were reduced by reimbursements from Intel of $32 million and $22 million for the first quarters of 2013 and 2012, respectively.

IMFS: We partnered with Intel in 2007 to form IM Flash Singapore, LLP ("IMFS") to manufacture NAND Flash memory products for the exclusive use of the members. In the third quarter of 2012, we acquired Intel's remaining interest in IMFS and terminated IMFS' supply agreement with us and Intel.

Supply Agreements: IMFT sells products to the joint venture members generally in proportion to their ownership interests at long-term negotiated prices approximating cost. IMFS also sold product to us and Intel generally in proportion to our ownership interests at long-term negotiated prices approximating cost. Due to changes in the ownership interest of IMFS, our share of its output grew from 57% at the beginning of the first quarter of 2012 to 78% in the second quarter of 2012. As a result of our acquisition of Intel's remaining interest in IMFS and other IM Flash restructuring agreements with Intel, Intel has not had rights to the output from either IMFS or our Virginia facility since the third quarter of 2012. Subsequent to the third quarter of 2012, we also sell NAND Flash products to Intel under a cost-plus supply arrangement.

Aggregate NAND Flash sales to Intel were $148 million and $261 million for the first quarters of 2013 and 2012, respectively. Receivables from Intel for sales of NAND Flash products as of November 29, 2012 and August 30, 2012 were $87 million and $103 million, respectively.

IM Flash distributions and contributions: The following table presents IM Flash's distributions to and contributions from its shareholders ("IM Flash" includes both IMFT and IMFS for the first quarter of 2012 and includes only IMFT for the first quarter of 2013):



Quarter ended	November 29, 2012		December 1, 2011
IM Flash distributions to Micron	$	—	$	86
IM Flash distributions to Intel	—		83
Micron contributions to IM Flash	—		103
Intel contributions to IM Flash	—		131

MP Mask

In 2006, we formed a joint venture with Photronics to produce photomasks for leading-edge and advanced next generation semiconductors. At inception and through November 29, 2012, we owned 50.01% and Photronics owned 49.99% of MP Mask. We contributed $8 million to MP Mask and Photronics contributed $7 million to MP Mask in the first quarter of 2012. In connection with the formation of the joint venture, we received $72 million in 2006 in exchange for entering into a license agreement with Photronics, which is being recognized over the term of the 10-year agreement. Deferred income and other noncurrent liabilities included an aggregate of $25 million and $26 million as of November 29, 2012 and August 30, 2012, respectively, related to this agreement. We purchase a substantial majority of the reticles produced by MP Mask pursuant to a supply arrangement.

The following table presents the assets and liabilities of MP Mask included in our consolidated balance sheets, excluding intercompany balances:



As of	November 29, 2012		August 30, 2012
Current assets	$	21	$	19
Noncurrent assets (primarily property, plant and equipment)	168		170
Current liabilities	12		12

Creditors of MP Mask have recourse only to the assets of MP Mask and do not have recourse to any other of our assets.

Policy Text Block [Abstract]
Variable Interest Entities	We have interests in entities that are Variable Interest Entities ("VIEs"). If we are the primary beneficiary of a VIE, we are required to consolidate it. To determine if we are the primary beneficiary, we evaluate whether we have the power to direct the activities that most significantly impact the VIE's economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Our evaluation includes identification of significant activities and an assessment of our ability to direct those activities based on governance provisions and arrangements to provide or receive product and process technology, product supply, operations services, equity funding, financing and other applicable agreements and circumstances. Our assessments of whether we are the primary beneficiary of our VIEs require significant assumptions and judgment.

- Definition

Disclosure of accounting policy for consolidation to describe the significant judgments and assumptions made in determining whether a variable interest held by the entity requires the variable interest entity to be consolidated and (or) disclose information about its involvement with the variable interest entity; the methodology used by the entity for determining whether or not it is the primary beneficiary of the variable interest entity; and the significant factors considered and judgments made in determining that the power to direct the activities that significantly impact the economic performance of the variable interest entity are shared (as defined).
