	Business and Basis of Presentation
	Micron Technology, Inc., including its consolidated subsidiaries, (hereinafter referred to collectively as "we," "our," "us" and similar terms unless the context indicates otherwise) is one of the world's leading providers of advanced semiconductor solutions. Through our worldwide operations, we manufacture and market a full range of DRAM, NAND Flash and NOR Flash memory, as well as other innovative memory technologies, packaging solutions and semiconductor systems for use in leading-edge computing, consumer, networking, automotive, industrial, embedded and mobile products. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America consistent in all material respects with those applied in our Annual Report on Form 10-K for the year ended August 29, 2013. In the opinion of our management, the accompanying unaudited consolidated financial statements contain all necessary adjustments, consisting of a normal recurring nature, to present fairly the financial information set forth herein. Certain reclassifications have been made to prior period amounts to conform to current period presentation.
	Our fiscal year is the 52 or 53-week period ending on the Thursday closest to August 31. Our second quarters of fiscal 2014 and 2013 ended on February 27, 2014 and February 28, 2013, respectively.

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 judgments.
	Unconsolidated Variable Interest Entities
	Inotera: Inotera Memories, Inc. ("Inotera") is a VIE because its equity is not sufficient to permit it to finance its activities without additional support from its shareholders. 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 Technology Corporation ("Nanya") for financing and the ability of Inotera to operate in Taiwan. Therefore, we do not consolidate Inotera and we account for our interest under the equity method. See "Equity Method Investments – Inotera" 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 ("Financing Entities"). Neither we nor the Financing Entities 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 Financing Entities and because the third-party equity holder lacks characteristics of a controlling financial interest. By design, the arrangements with the EQUVO Entities are merely financing vehicles 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.
	SC Hiroshima Energy Corporation: SC Hiroshima Energy Corporation ("SCHE") is an entity created to construct and operate a cogeneration, electrical power plant to support our wafer manufacturing facility in Hiroshima, Japan. SCHE is a VIE due to the nature of its tolling agreements with us and our purchase and call options for SCHE's assets. We do not have an equity ownership interest in SCHE. We do not control the operation and maintenance of the plant, which we have determined are the activities of SCHE that most significantly impacts its economic performance. Therefore, we do not consolidate SCHE.
	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.  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.  As a result, we have determined that we have the power to direct the activities of IMFT that most significantly impact its economic performance and, therefore, we consolidate IMFT.
	MP Mask: MP Mask Technology Center, LLC ("MP Mask") is a VIE because substantially 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 have tie-breaking voting rights over key operating decisions and 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.  As a result, we have determined that we have the power to direct the activities of MP Mask that most significantly impact its economic performance and, therefore, we consolidate MP Mask.

	Elpida Memory, Inc.
	On July 31, 2013, we acquired Elpida Memory, Inc. ("Elpida") and 89% of Rexchip Electronics Corporation ("Rexchip''), now known as Micron Memory Taiwan Co., Ltd. ("MMT") for an aggregate of $949 million in cash (collectively, the "Elpida Acquisition"). In the second quarter of 2014, we purchased an additional 9.87% of MMT's outstanding common stock. (See "Equity – Noncontrolling Interest in Subsidiaries – MMT" note.) Both Elpida and MMT manufacture semiconductor memory products including mobile DRAM targeted toward mobile phones and tablets.
	In connection with the Elpida Acquisition, we recorded net assets of $2,601 million and noncontrolling interests of $168 million. Because the fair value of the net assets acquired, less noncontrolling interests, exceeded our purchase price, we recognized a gain on the acquisition of $1,484 million. In the second quarter of 2014, the provisional amounts as of the acquisition date were adjusted, primarily for pre-petition liabilities. As a result, we recorded a charge of $33 million in the second quarter of 2014 in other non-operating expense for these measurement period adjustments to adjust the gain on the acquisition of Elpida.
	The following unaudited pro forma financial information presents the combined results of operations as if the Elpida Acquisition had occurred on September 2, 2011.  The pro forma financial information includes the accounting effects of the business combination, including adjustments to the amortization of intangible assets, depreciation of property, plant and equipment, interest expense and elimination of intercompany activities.  The unaudited pro forma financial information for the quarter and six months ended February 28, 2013 includes our results for the quarter and six months ended February 28, 2013 and the results of Elpida and MMT, including the adjustments described above, for the quarter and six months ended December 31, 2012.

	Inotera
	We have partnered with Nanya in Inotera, a Taiwan DRAM memory company, since the first quarter of 2009.  As of February 27, 2014, we held a 35% ownership interest, Nanya and its affiliates held a 36% ownership interest and the remaining ownership interest in Inotera was publicly held.
	As of February 27, 2014, the market value of our equity interest in Inotera was $1.81 billion based on the closing trading price of its shares in an active market. As of February 27, 2014 and August 29, 2013, there were gains of $45 million and $44 million, respectively, in accumulated other comprehensive income (loss) for cumulative translation adjustments from our equity investment in Inotera.
	As of December 31, 2013, Inotera's current liabilities exceeded its current assets by $129 million, which exposes Inotera to liquidity risk. As of December 31, 2013, Inotera was not in compliance with certain loan covenants and had not been in compliance for the past several years. The terms of the loan covenants require Inotera to cure the noncompliance no later than June 30, 2014. Inotera has requested a waiver from complying with the December 31, 2013 financial covenants. For the year ended December 31, 2013, Inotera generated net income of $703 million, which has improved its liquidity.
	Through December 2012, we had rights and obligations to purchase 50% of Inotera's wafer production capacity based on a margin-sharing formula among Nanya, Inotera and us. In the second quarter of 2013, we entered into agreements with Nanya and Inotera to amend the joint venture relationship involving Inotera. The amendments included a new supply agreement (the "Inotera Supply Agreement") with Inotera under which we were obligated to purchase for an initial period through December 2015 substantially all of Inotera's output at a purchase price based on a discount from market prices for our comparable components. The Inotera Supply Agreement contemplates annual negotiations with respect to potential successive one-year extensions, and if in any year the parties do not agree to an extension, the agreement will terminate following the end of the then-existing term plus a subsequent three-year wind-down period. Our share of Inotera's capacity would decline over the three year wind-down period. In the second quarter of 2014, we extended the initial period of the Inotera Supply Agreement through December 2016. Under the Inotera supply agreements, we purchased $714 million and $1,301 million of DRAM products in the second quarter and first six months of 2014, respectively, and $200 million and $401 million in the second quarter and first six months of 2013, respectively.
	Pursuant to a cost-sharing arrangement with Nanya, which was effective through December 31, 2012, our research and development ("R&D") costs were reduced by $4 million and $19 million in the second quarter and first six months of 2013, respectively. Nanya ceased participating in the joint development program after December 31, 2012.
	Tera Probe
	In the fourth quarter of 2013, as part of the Elpida Acquisition, we acquired a 40% interest in Tera Probe, Inc. ("Tera Probe"), which provides semiconductor wafer testing and probe services to us and others. The initial net carrying value of our investment was less than our proportionate share of Tera Probe's equity and the difference is being amortized as a credit to earnings through equity in net income (loss) of equity method investees (the "Tera Probe Amortization"). As of February 27, 2014, the remaining balance of the Tera Probe Amortization was $32 million and is expected to be amortized over a weighted-average period of 6 years. As of February 27, 2014, based on the closing trading price of Tera Probe's shares in an active market, the market value of our equity interest was $42 million. Included in our cost of goods sold for the second quarter and first six months of 2014 is $31 million and $64 million, respectively, for services performed by Tera Probe.
	Other
	Aptina: Other equity method investments included a 30% 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 results of operations.
	In the second quarter and first six months of 2013, we recognized net sales of $48 million and $109 million, respectively, and cost of goods sold of $57 million and $138 million, respectively, from products sold to Aptina under a wafer supply agreement. In the third quarter of 2013, in connection with our sale of Micron Technology Italia, S.r.l. ("MIT") to LFoundry Marsica S.r.l. ("LFoundry"), we assigned to LFoundry our supply agreement with Aptina to manufacture image sensors at MIT. In 2013, we also loaned $45 million to Aptina under a short-term, interest-free, unsecured agreement which was repaid in the first six months of 2014.

	(1) We have the obligation or option to pay cash for the aggregate amount due upon conversion for all of our convertible notes. Since it is our current intent to settle in cash the principal amount of all of our convertible notes upon conversion, the dilutive effect of such notes on earnings per share is computed under the treasury stock method.
	(2) Since the closing price of our common stock for at least 20 trading days in the 30 trading day period ending on December 31, 2013 exceeded 130% of the initial conversion price per share, holders have the right to convert their notes at any time during the calendar quarter ended March 31, 2014.
	(3) As a result of these notes being convertible at the option of the holder through March 31, 2014, and because the terms of these notes would require us to pay cash for the principal amount of any converted notes, amounts are classified as current.
	Debt Restructure
	During the first and second quarters of 2014, we initiated a series of actions to restructure our debt as follows:
	Exchange Transactions
	•	In November 2013, we exchanged $440 million in aggregate principal amount of our 2027 Notes, 2031A Notes and 2031B Notes into 3.00% Convertible Senior Notes due 2043.
	Debt Conversions and Settlements
	•	In November 2013, we announced the termination of the conversion rights for our remaining 2027 Notes, effective on December 13, 2013;
	•	In November 2013, we called for the redemption of our remaining 2031A Notes on December 7, 2013; and
	•	In January 2014, we called for the redemption of our remaining 2014 Notes on March 3, 2014.
	During the first and second quarters of 2014, substantially all of the holders of these notes exercised their options to convert their notes and, in each case, we elected to settle the conversion amounts entirely in cash.
	Cash Repurchases
	•	In January 2014, we repurchased $164 million in aggregate principal amount of our 2031B Notes, 2032C Notes and 2032D Notes in privately-negotiated transactions for an aggregate of $407 million in cash.
	Issuance of Non-Convertible Notes
	•	In February 2014, we issued $600 million in principal amount of 5.875% senior notes due February 2022.
	Exchange Transactions: On November 12, 2013, in a series of separate non-cash transactions, we exchanged portions of our 2027 Notes, 2031A Notes and 2031B Notes (collectively, the "Exchanged Notes") into 3.00% Convertible Senior Notes due 2043 (the "2043G Notes") (collectively, the "Exchange Transactions"). In connection with the Exchange Transactions, which were accounted for as extinguishments, we issued to holders of the Exchanged Notes new 2043G Notes with an aggregate principal amount at issuance of $820 million, which accretes up to a principal amount at maturity of $1,025 million (see further discussion in "2043G Notes" below). The liability and equity components of the Exchanged Notes had previously been stated separately within debt and additional capital in our consolidated balance sheet. As a result, our accounting for the Exchanged Notes affected debt and equity. In connection with the Exchanged Notes, we recognized a loss of $38 million based on the difference between the carrying values and the fair values of the debt components of the Exchanged Notes (based on Level 2 fair value measurements), which was included in other non-operating expense for the first quarter of 2014. The table below summarizes the Exchange Transactions:
			Principal Amount				Carrying Value of Debt				Equity
	Amounts reduced in connection with the Exchanged Notes:
	2027 Notes		$	80			$	68			$	51
	2031A Notes		155				125				148
	2031B Notes		205				152				212
			440				345				411

	2043G Notes		1,025				627				173
	Net increase (decrease) as a result of the Exchange Transactions		$	585			$	282			$	(238	)
	Debt Conversions and Settlements: During the first and second quarters of 2014, we initiated a series of actions resulting in a number of debt conversions and settlements. Those actions included the following:
	Termination of Conversion Rights of our 2027 Notes – On November 7, 2013, we announced the termination of the conversion rights for our remaining 2027 Notes, effective on December 13, 2013. During the first and second quarters of 2014, substantially all of holders of our 2027 Notes exercised their option to convert their notes and, in each case, we elected to settle the conversion amount entirely in cash.
	Redemption of our 2031A Notes – On November 7, 2013, we called for the redemption of our remaining 2031A Notes on December 7, 2013. During the first and second quarters of 2014, substantially all of holders of our 2031A Notes exercised their option to convert their notes and, in each case, we elected to settle the conversion amount entirely in cash.
	Redemption of our 2014 Notes – On January 31, 2014, we called for the redemption of our remaining 2014 Notes on March 3, 2014. During the second quarter of 2014, substantially all of the holders of our 2014 Notes exercised their option to convert their notes and, in each case, we elected to settle the conversion amount entirely in cash.
	As a result of our elections to settle the conversion amounts in cash, each of the settlement obligations became derivative debt liabilities subject to mark-to-market accounting treatment. Under the terms of the indentures for the above notes, cash settlement amounts for these derivative debt liabilities are determined based on the shares underlying the converted notes multiplied by the volume-weighted-average price of our common stock over a period of 20 consecutive trading days, beginning three days after the holder's election to convert their notes. Therefore, we reclassified the fair values of the equity components of each of the converted notes from additional capital to derivative debt liabilities within current debt in our consolidated balance sheet. In connection with the above, we used an aggregate of $728 million in cash in the second quarter of 2014 to settle conversion activities. A summary of the conversion activities for these notes is as follows:
			Debt Principal Converted				Carrying Value of Debt Converted				Equity Component Reclassified To Debt(1)				Mark-to-Market Loss(Gain)(2)				Loss on Settlement(2)
	Quarter ended November 28, 2013:

(1) Based on Level 2 fair value measurements.
(2) Included in non-operating expense.
In the third quarter of 2014, we used an aggregate of $718 million in cash to settle the remaining 2014 Notes. In connection therewith, we incurred an additional aggregate $8 million of mark-to-market and settlement losses for the 2014 Notes.
Cash Repurchases: In January 2014, we repurchased $164 million in aggregate principal amount of our 2031B Notes, 2032C Notes and 2032D Notes (collectively, the "Repurchased Notes") in privately-negotiated transactions for an aggregate of $407 million in cash. The liability and equity components of the Repurchased Notes had previously been stated separately within debt and additional capital in our consolidated balance sheet. As a result, our accounting for the Repurchased Notes reduced a component of debt and a component of equity. In connection with the Repurchased Notes, we recognized a loss of $11 million (based on Level 2 fair value measurements), which is included in other non-operating expense in the second quarter of 2014. The table below summarizes activity in the second quarter of 2014 with respect to Repurchased Notes:
		Principal Amount				Carrying Value of Debt				Equity
2031B Notes		$	26			$	19			$	43
2032C Notes		100				85				159
2032D Notes		38				31				60
		$	164			$	135			$	262
Issuance of Non-Convertible Notes: On February 5, 2014, we issued $600 million in principal amount of 5.875% Senior Notes due February 2022 (the "2022 Notes"). Issuance costs for the 2022 Notes totaled $14 million.
The 2022 Notes contain covenants that, among other things, limit, in certain circumstances, our ability and/or the ability of our domestic restricted subsidiaries (which are generally subsidiaries in the U.S. in which we own at least 80% of the voting stock) to (1) create or incur certain liens and enter into sale and lease-back transactions, (2) create, assume, incur or guarantee certain additional secured indebtedness and unsecured indebtedness of certain of our domestic restricted subsidiaries, and (3) consolidate with or merge with or into, or convey, transfer or lease all or substantially all of our assets, to another entity. These covenants are subject to a number of limitations, exceptions and qualifications.
Cash Redemption at Our Option: Prior to February 15, 2017, we may redeem the 2022 Notes, in whole or in part, at a price equal to the principal amount of the 2022 Notes to be redeemed plus a make-whole premium as described in the indenture governing the 2022 Notes, together with accrued and unpaid interest. Additionally, we may use the net cash proceeds of one or more equity offerings to redeem up to 35% of the aggregate principal amount of the 2022 Notes at a price equal to 105.875% of the principal amount together with accrued and unpaid interest. On or after February 15, 2017, we may redeem the 2022 Notes, in whole or in part, at prices above principal amount that decline over time, as specified in the indenture, together with accrued and unpaid interest.
Elpida Creditor Installment Payments
In October 2013, we made the first Elpida creditor installment payment of $534 million from funds that had been held in a current restricted cash account since the acquisition date. The remaining payments are due at the end of each calendar year from 2014 through 2019.
2043G Notes
In connection with the Exchange Transactions, on November 12, 2013, we issued $1,025 million principal amount of 2043G Convertible Senior Notes (the "2043G Notes"). Each $1,000 principal amount at maturity had an original issue price of $800. An amount equal to the difference between the original issue price and the principal amount at maturity will accrete in accordance with a schedule set forth in the indenture.  The initial conversion rate for the 2043G Notes is 34.2936 shares of common stock per $1,000 principal amount at maturity, equivalent to an initial conversion price of approximately $29.16 per share of common stock.
Upon issuance of the 2043G Notes, we recorded $627 million of debt, $173 million of additional capital and $5 million of deferred debt issuance costs (included in other noncurrent assets). The amount recorded as debt was based on the fair value of the debt component as a standalone instrument and was determined using an average interest rate for similar nonconvertible debt issued by entities with credit ratings comparable to ours at the time of issuance (Level 2 fair value measurements). We recorded a debt discount of $398 million for the difference between the debt recorded at inception and the principal amount at maturity. Holders of the 2043G Notes have the right to require us to repurchase all or a portion of their notes on November 15, 2028 at the accreted principal amount, which is scheduled to be $917 million at such date. We have the option to pay cash, issue shares of common stock or any combination thereof, for the aggregate amount due upon conversion. It is our current intent to settle in cash the principal amount of the 2043G Notes upon conversion. As a result, the dilutive effect of the 2043G Notes in earnings per share is computed under the treasury stock method.
Conversion Rights: Holders may convert their 2043G Notes under the following circumstances: (1) if the 2043G Notes are called for redemption; (2) during any calendar quarter if the closing price of our common stock for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is more than 130% of the conversion price (approximately $37.91 per share) of the 2043G Notes; (3) if the trading price of the 2043G Notes is less than 98% of the product of the closing price of our common stock and the conversion rate of the 2043G Notes during the periods specified in the indenture; (4) if specified distributions or corporate events occur, as set forth in the indenture; or (5) at any time after August 15, 2043.
Cash Redemption at Our Option: Prior to November 20, 2018, we may redeem for cash the 2043G Notes if the closing price of our common stock is more than 130% of the conversion price for at least 20 trading days in the 30 consecutive trading days ending within five trading days prior to the date on which we provide notice of redemption. The redemption price would equal the principal amount at maturity plus accrued and unpaid interest. On or after November 20, 2018, we may redeem for cash the 2043G Notes without regard to the closing price of our common stock. The redemption price would equal the accreted principal amount plus accrued and unpaid interest. If we redeem the 2043G Notes prior to November 20, 2018, we are required to pay in cash a make-whole premium as specified in the indenture.
Cash Repurchase at the Option of the Holder: Holders of the 2043G Notes may require us to repurchase for cash all or a portion of the 2043G Notes on November 15, 2028. The repurchase price is equal to the accreted principal amount at such date plus accrued and unpaid interest. Holders of the 2043G Notes may also require us to repurchase for cash all or a portion of their 2043G Notes at a repurchase price equal to the accreted principal amount plus accrued and unpaid interest upon a change in control or a termination of trading, as defined in the indenture.
2019 Notes
On December 20, 2013, we issued $462 million in principal amount of 1.258% Secured Notes due January 2019 (the "2019 Notes"). The 2019 Notes mature on January 15, 2019 and are collateralized by certain equipment which had a carrying value of $240 million as of February 27, 2014. The principal amount of the 2019 Notes is payable in 10 consecutive semi-annual installments payable in January and July of each year, commencing in July 2014. The Export-Import Bank of the United States ("Ex-Im Bank") guaranteed payment of all regularly scheduled installment payments of principal of, and interest on, the 2019 Notes. We paid $23 million to Ex-Im Bank for its guarantee upon issuance of the 2019 Notes.
The 2019 Notes contains covenants which are customary for financings of this type, including negative covenants that limit or restrict our ability to create liens or dispose of the equipment securing the 2019 Notes. Events of default also include, among others, the occurrence of any event or circumstance that, in the reasonable judgment of Ex-Im Bank, is likely materially and adversely to affect our ability to perform any payment obligation, or any of our other material obligations under the indenture, the 2019 Notes or under any other related transaction documents to which Ex-Im Bank is a party.
Cash Redemption at Our Option: At any time prior to the maturity date of the 2019 Notes, we may redeem the 2019 Notes, in whole or in part, at a price equal to the principal amount of the 2019 Notes to be redeemed plus a make-whole premium as described in the indenture, together with accrued and unpaid interest.
Other Notes Payable
On February 27, 2014, in connection with our acquisition of an additional 9.87% interest in MMT, we recorded a $127 million note payable to the seller in monthly installments, without interest, from March 2014 through December 2014.
Convertible Notes With Debt and Equity Components
Accounting standards for convertible debt instruments that may be fully or partially settled in cash upon conversion require the debt and equity components to be separately accounted for in a manner that reflects a nonconvertible borrowing rate when interest expense is recognized in subsequent periods. The amount initially recorded as debt is based on the fair value of the debt component as a standalone instrument, determined using an average interest rate for similar nonconvertible debt issued by entities credit ratings similar to ours at the time of issuance. The difference between the debt recorded at inception and its principal amount is accreted to principal through interest expense through the estimated life of the note.
The terms of certain of our convertible notes give holders the right to require us to repurchase all or a portion of their notes at a date or dates earlier than the contractual maturity of the notes or upon the occurrence of certain events or circumstances. In these cases, we amortize any initial debt discount or imputed interest over the period from issuance of the notes through the earliest date that holders can require us to repurchase all or a portion of their notes. As a result, the period of amortization can be significantly shorter than the contractual maturity. (See "Holder Put Date" in the table below.)
As of February 27, 2014, the trading price of our common stock was higher than the initial conversion prices of all of our outstanding convertible notes, except for the 2043G Notes. As a result, the conversion values were in excess of principal amounts for such notes. The following table sets forth, as of February 27, 2014, a summary of certain features of our convertible notes:

	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.
	Rambus
	On May 5, 2004, Rambus, Inc. ("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.
	We were engaged in litigation with Rambus relating to certain of Rambus' patents and certain of our claims and defenses. Our lawsuits with Rambus related to patent matters were 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.
	In December 2013, we settled all pending litigation between us and Rambus, including all antitrust and patent matters.  We also entered into a 7-year term patent cross-license agreement with Rambus that allows us to avoid costs of patent-related litigation during the term.  We agreed to pay Rambus up to $10 million per quarter over seven years, for a total of $280 million, beginning in the second quarter of 2014.  The primary benefits we received from these arrangements were (1) the settlement and termination of all existing litigation, (2) the avoidance of future litigation expenses and (3) the avoidance of future management and customer disruptions.  As a result, other operating expense for the first quarter of 2014 included a $233 million charge to accrue a liability, which reflects the discounted value of amounts due under this arrangement.
	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.
	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, including Elpida Memory, Inc. and Elpida Memory (USA) Inc. (collectively “Elpida”).  On August 22, 2013, the plaintiffs filed a third amended complaint. The third amended complaint alleges that certain of our DRAM and image sensor products infringe four U.S. patents and that certain Elpida DRAM products infringe two U.S. patents and seeks damages, attorneys' fees, and costs. Trial currently is scheduled for February 8, 2016. On March 23, 2012, Elpida filed a Notice of Filing and Hearing on Petition Under Chapter 15 of the U.S. Bankruptcy Code and Issuance of Provisional Relief that included an order of the U.S. Bankruptcy Court for the District of Delaware staying judicial proceedings against Elpida. Accordingly, the plaintiffs' case against Elpida is stayed.
	On December 5, 2011, the Board of Trustees for the University of Illinois (the "University") 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 Patent Trial and Appeal Board (“PTAB”) held a hearing in connection with the three petitions on December 9, 2013. On March 10, 2014, the PTAB issued written decisions finding that each and every claim in the three patents in suit is invalid, and cancelled all claims. The University has a right to appeal the PTAB rulings to the U.S. Court of Appeals for the Federal Circuit.
	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. On September 24, 2013, the Court entered an order staying our case pending the resolution of co-pending cases brought by Semcon Tech, LLC against Applied Materials and Ebara Technologies, Inc. Subsequently these cases were resolved, and on February 21, 2014, the Court lifted the stay of the case against us. Trial currently is for August 21, 2015.
	On December 7, 2007, Tessera, Inc. filed a patent infringement against Elpida Memory, Inc., Elpida Memory (USA) Inc. (collectively "Elpida"), and numerous other defendants, in the United States District Court for the Eastern District of Texas. The complaint alleges that certain Elpida products infringe four U.S. patents and seeks injunctive relief, damages, attorneys' fees, and costs. Prior to answering the complaint, Elpida and other defendants filed motions to stay the case pending final resolution of a case before the International Trade Commission ("ITC") against Elpida and other respondents, alleging infringement of the same patents asserted in the Eastern District of Texas case (In The Matter of Certain Semiconductor Chips with Minimized Chip Package Size and Products Containing Same (III), ITC No. 337-TA-630 (the "ITC Action")). On February 25, 2008, the Eastern District of Texas Court granted the defendants' motion to stay the action. On December 29, 2009, the ITC issued a Notice of Final Determination in the ITC Action finding no violation by Elpida. Tessera Inc. subsequently appealed the matter to the U.S. Court of Appeals for the Federal Circuit. On May 23, 2011, the Federal Circuit affirmed the ITC's Final Determination. The Eastern District of Texas case currently remains stayed.
	Among other things, the above lawsuits pertain to certain of our DDR, DDR2, DDR3, SDR SDRAM, PSRAM, RLDRAM, LPSDR, NAND Flash, image sensor products and certain other memory products we manufacture, 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
	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 were 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. We paid the full amount into an escrow account by the end of the first quarter of 2013 in accordance with the settlement agreement.
	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 above discussion of the U.S. indirect purchaser cases. 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.
	Securities Matters
	On July 12, 2013, seven former shareholders of Elpida Memory, Inc. ("Elpida") filed a complaint against Messrs. Sakamoto, Adachi, Gomi, Shirai, Tsay-Jiu, Wataki, Kinoshita, and Takahasi in their capacity as members of the board of directors of Elpida as of February 2013. The complaint alleges that the defendants engaged in various acts and misrepresentations to hide the financial condition of Elpida and deceive shareholders prior to Elpida filing a petition for corporate reorganization on February 27, 2013. The plaintiffs seek joint and several damages equal to the market value of shares owned by each of the plaintiffs on February 23, 2013, along with attorneys’ fees and interest. At a hearing on September 25, 2013, the plaintiffs withdrew the complaint against Mr. Tsay-Jiu.
	We are unable to predict the outcome of this matter and therefore cannot estimate the range of possible loss.  The final resolution of this matter could result in significant liability and could have a material adverse effect on our business, results of operations or financial condition.
	Qimonda
	On January 20, 2011, Dr. Michael Jaffé, administrator for Qimonda AG ("Qimonda") insolvency proceedings, filed suit against Micron Technology, Inc. (“Micron Technology”) and Micron Semiconductor B.V., our Netherlands subsidiary (“Micron B.V.”), 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 Micron B.V. and Qimonda signed in fall 2008 pursuant to which Micron B.V. purchased substantially all of Qimonda's shares of Inotera Memories, Inc. (the “Inotera Shares”) and seeks an order requiring us to retransfer those shares to the Qimonda estate. The complaint also seeks, among other things, to recover damages for the alleged value of the joint venture relationship with Inotera and 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.
	Following a series of hearings with pleadings, arguments and witnesses on behalf of the Qimonda estate, on March 13, 2014, the Court issued judgments:  (i) ordering Micron B.V. to pay approximately $1 million in respect of certain Inotera shares sold in connection with the original share purchase; (ii) ordering Micron B.V. to disclose certain information with respect to any Inotera Shares sold by it to third parties; (iii) ordering Micron B.V. to disclose the benefits derived by it from ownership of the Inotera Shares, including in particular, any profits distributed on such shares and all other benefits; (iv) denying Qimonda’s claims against Micron Technology for any damages relating to the joint venture relationship with Inotera; and (v) determining that Qimonda's obligations under the patent cross-license agreement are cancelled. In addition, the Court issued interlocutory judgments ordering, among other things:  (i) that Micron B.V. transfer to the Qimonda estate the Inotera Shares still owned by it and pay to the Qimonda estate compensation in an amount to be specified for any Inotera Shares sold to third parties; and (ii) that Micron B.V. pay the Qimonda estate as compensation an amount to be specified for benefits derived by it from ownership of the Inotera Shares. The interlocutory judgments have no immediate, enforceable effect on us, and, accordingly, we expect to be able to continue to operate with full control of the Inotera Shares subject to further developments in the case. All of these judgments are immediately appealable, and we have until April 28, 2014 to file a notice of appeal.
	We are unable to predict the outcome of the matter 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, unspecified damages based on the benefits derived by Micron B.V. from the ownership of the Inotera Shares, and/or 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 February 27, 2014, the Inotera Shares had a carrying value for purposes of our financial reporting of $312 million and a market value of $1,002 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.

	Redeemable Convertible Notes
	Under the terms of the indentures of the 2031B and 2033E and 2033F Notes, upon conversion, we would be required to pay cash equal to the lesser of (1) the aggregate principal amount or (2) the conversion value of the notes being converted (we could pay cash, shares of common stock or a combination thereof, at our option, for the remainder, if any, of our conversion obligation). Therefore, the 2031B, 2033E and 2033F Notes were classified as current debt. Since these notes were convertible at the option of the holder and the principal amount of any converted notes would be required to be paid in cash, the aggregate difference of $91 million between the principal amount and the carrying value was classified as redeemable convertible notes in the mezzanine section of the accompanying consolidated balance sheet as of February 27, 2014.

	IMFT
	Since its inception in 2006 through February 27, 2014, we have owned 51% of IMFT, a venture between us and Intel to manufacture NAND Flash memory products and 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 cumulative 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 to us, 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.
	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 R&D cost of certain emerging memory technologies. Our R&D expenses were reduced by reimbursements from Intel of $35 million and $64 million for the second quarter and first six months of 2014, respectively, and $34 million and $66 million for the second quarter and first six months of 2013, respectively.
	We sell a portion of our products to Intel through our IMFT joint venture at long-term negotiated prices approximating cost. Sales of NAND Flash products to Intel under this arrangement were $104 million and $205 million for the second quarter and first six months of 2014, respectively, and $91 million and $190 million for the second quarter and first six months of 2013, respectively. Receivables from Intel for IMFT sales of NAND Flash products as of February 27, 2014 and August 29, 2013, were $62 million and $68 million, respectively.

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 February 27, 2014, we owned 50.01% and Photronics owned 49.99% of MP Mask. 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 $16 million and $19 million as of February 27, 2014 and August 29, 2013, respectively, related to this agreement. We purchase a substantial majority of the reticles produced by MP Mask pursuant to a supply arrangement.

Creditors of MP Mask have recourse only to the assets of MP Mask and do not have recourse to any other of our assets.
MMT
As a result of the acquisition of Elpida and MMT on July 31, 2013, noncontrolling interests in subsidiaries in our consolidated balance sheet included an approximate 11.11% ownership interest in MMT. In the second quarter of 2014, we purchased an additional 9.87% of MMT's outstanding common stock for $136 million. The purchase of substantially all of the shares was financed with a short-term loan from a seller. (See "Debt – Other Notes Payable" note.) As a result of the purchase of MMT shares, noncontrolling interest decreased by $167 million and additional capital increased by $31 million in the second quarter of 2014.

Derivative Financial Instruments	'
	Derivative Instruments
	We use derivative instruments to manage a portion of our exposure to changes in currency exchange rates and variable interest rates.  We also have convertible note settlement obligations which became derivative instruments as a result of our elections to settle conversions in cash. We do not use derivative instruments for speculative purpose.
	Derivative Instruments without Hedge Accounting Designation
	Currency Derivatives: We use derivative instruments to manage a portion of our exposure to changes in currency exchange rates from 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.
	To hedge our exposures to monetary assets and liabilities, we generally utilize a rolling hedge strategy with currency forward contracts that mature within 35 days.  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 (Level 2 fair value measurements). In connection with the currency exchange rate risk associated with our acquisition of Elpida and the MMT shares in July 2013, we entered into currency exchange transactions (the "Elpida Acquisition Hedges"). The Elpida Acquisition Hedges were not designated for hedge accounting and were remeasured at fair value each period. We recorded losses from the Elpida Acquisition Hedges of $120 million and $178 million in the second quarter and first six months of 2013, respectively. To mitigate the risk that increases in exchange rates have on Elpida creditor installment payments due in December 2014 and December 2015, we entered into forward contracts to purchase 20 billion yen on November 28, 2014 and 10 billion yen on November 27, 2015.
	Realized and unrealized gains and losses on currency derivatives without hedge accounting designation as well as the change in the underlying monetary assets and liabilities due to changes in currency exchange rates are included in other non-operating income (expense).
	Interest Rate Swaps: We are party to interest rate swap contracts that mature in August 2017 to hedge against the variability of future interest payments due on floating-rate debt, which effectively converts the floating-rate debt to fixed-rate debt. Our primary objective of entering into interest rate swap contracts is to reduce the volatility that changes in interest rates on floating-rate debt have on interest expense. As of February 27, 2014, the principle balance on the floating-rate debt was $273 million. We designated 80% of the swaps as cash flow hedges and the remaining 20% were not designated for hedge accounting treatment. The fair values of the interest rate swaps are calculated by discounting the expected future cash flows based on inputs that are readily available in publicly quoted markets (Level 2 fair value measurements). Changes in the fair value of the undesignated portion are included in interest expense.
	Convertible Notes Settlement Obligations: In connection with our debt restructure activities in the first six months of 2014, our settlement obligations for the 2014 Notes, 2027 Notes and 2031A Notes became derivative instruments for an approximate 30-day period ending on their respective settlement dates. The settlement dates varied through the first, second and third quarters of 2014. The fair values of the underlying conversion options were initially determined using the Black-Scholes option valuation model (Level 2 fair value measurements). The Black-Scholes model requires the input of assumptions, including the stock price, expected stock-price volatility, estimated option life, risk-free interest rate and dividend rate. Subsequent measurements of our convertible notes settlement obligations were based on the volume-weighted-average stock price (Level 1 fair value measurements). Changes in fair values of the derivative settlement obligations were included in other non-operating income (expense).
	Total gross notional amounts and fair values for derivative instruments without hedge accounting designation were as follows:

	Derivative Instruments with Cash Flow Hedge Accounting Designation
	Currency Derivatives: 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 (Level 2 fair value measurements).  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, maturity, volatility and credit-risk spread (Level 2 fair value measurements).
	Interest Rate Swaps: As noted above in “Derivative Instruments without Hedge Designation – Interest Rate Swaps,” we are party to interest rate swap contracts that mature in August 2017 to hedge against the variability in future interest payments due on $273 million of floating-rate debt and we designated 80% of the swaps as cash flow hedges.
	For derivative instruments designated as cash flow hedges, the effective portion of the realized and unrealized gain or loss on the derivatives is included as a component of accumulated other comprehensive income (loss).  For derivative instruments designated as cash flow hedges, the amounts in accumulated other comprehensive income (loss) 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. The ineffective or excluded portion of the realized and unrealized gain or loss is included in other non-operating income (expense).  Total gross notional amounts and fair values for derivative instruments with cash flow hedge accounting designation were as follows:
			Notional Amount			Fair Value of Current Liabilities (1)

	As of February 27, 2014

	Interest swap contracts		250			—

	(1)	Included in accounts payable and accrued expenses – other.
	For the first six months of 2014, we recognized $2 million of net pre-tax losses in accumulated other comprehensive income (loss) from the effective portion of cash flow hedges.  For the second quarter and first six months of 2013, we recognized $6 million and $10 million, respectively, of net pre-tax losses 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 non-operating income (expense) were not significant for the second quarters and first six months of 2014 and 2013.  The amounts reclassified from accumulated other comprehensive income (loss) for the second quarters and first six months of 2014 and 2013 were not significant. As of February 27, 2014, the amount of pre-tax net cash flow hedge gains included in accumulated other comprehensive income (loss) expected to be reclassified into earnings in the next 12 months was $7 million.
Derivative Counterparty Credit Risk and Master Netting Arrangements
Our derivative instruments expose us to credit risk to the extent the counterparties may be unable to meet the terms of the derivative instrument.  As of February 27, 2014, our maximum exposure to loss due to credit risk if counterparties fail completely to perform according to the terms of the contracts was generally 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 also seek to enter into master netting arrangements with our counterparties to mitigate credit risk in derivative hedge transactions. These master netting arrangements allow us and our counterparties to net settle amounts owed to each other. Derivative assets and liabilities that can be net settled under these arrangements have been presented in our consolidated balance sheet on a net basis. As of February 27, 2014, amounts netted were not significant.

Fair Value Measurements	'
	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	February 27, 2014								August 29, 2013

	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 February 27, 2014, no adjustments were made to such pricing information.
	Fair Value Measurements on a Nonrecurring Basis
	In connection with the Exchange Transactions, we determined the fair value for the debt component of the Exchanged Notes as if it were a stand-alone instrument using an interest rate for similar nonconvertible debt issued by entities with credit ratings comparable to ours at the time of issuance.
	In connection with the debt conversions and settlements in the first and second quarters of 2014, substantially all of the holders elected to convert their then outstanding 2014, 2031A and 2027 Notes. As a result of our elections to settle the conversion amounts in cash, each of the settlement obligations became derivative debt liabilities subject to mark-to-market accounting treatment for a period of approximately 30 days beginning on the date we notified the holder of our intention to settle the obligation in cash through the settlement date. The fair values of the underlying derivative settlement obligations were initially determined using the Black-Scholes option valuation model (Level 2 fair value measurements). The Black-Scholes model requires the input of assumptions, including the stock price, expected stock-price volatility, estimated option life, risk-free interest rate and dividend rate. The subsequent measurements and final settlement amounts of our convertible notes settlement obligations were based on the value-weighted average stock price (Level 1 fair value measurements). Changes in fair values of the derivative settlement obligations were included in other non-operating income (expense), net.
	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	February 27, 2014				August 29, 2013
		Fair		Carrying		Fair		Carrying
		Value		Value		Value		Value
	Convertible notes	$	5,693	$	2,658	$	4,167	$	2,506
	Elpida creditor installment payments and other notes	2,907		2,843		2,269		2,279
	The fair values of our convertible debt instruments were 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).

	As of February 27, 2014, we had an aggregate of 123 million shares of common stock reserved for the issuance of stock options and restricted stock awards, of which 66 million shares were subject to outstanding awards and 57 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 9 million and 11 million stock options during the second quarter and first six months of 2014, respectively, with weighted-average grant-date fair values per share of $9.58 and $9.17, respectively. We granted 13 million and 17 million stock options during the second quarter and first six months of 2013, respectively, with weighted-average grant-date fair values per share of $3.35 and $3.27, 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:

	On May 3, 2013, we sold MIT, a wholly-owned subsidiary, including its 200mm wafer fabrication facility assets in Avezzano, Italy, to LFoundry. In exchange for the shares of MIT, we received consideration from LFoundry valued at $35 million, substantially all of which was under a 7-year, non-interest bearing term note. Under the terms of the agreements, we assigned to LFoundry our supply agreement with Aptina for CMOS image sensors manufactured at the Avezzano facility. In the second quarter of 2013, we recorded an impairment loss of $62 million to write down the assets and liabilities to their estimated fair values in connection with the sale of MIT.
	Since the second quarter of 2010, we have held an equity method investment in Transform Solar Pty Ltd.

	Income taxes for the second quarter and first six months of 2014 included $55 million and $128 million, respectively, related to the utilization of deferred tax assets as a result of Elpida's operations.  Income taxes for the second quarter of 2013 included tax benefits related to two non-U.S. jurisdictions of $10 million for the favorable resolution of certain prior year tax matters, which was previously reserved as an uncertain tax position, and $9 million for a favorable change in tax law applicable to prior years.  Remaining taxes for the second quarters and first six months of 2014 and 2013 primarily reflect taxes on our non-U.S. operations. We have a full valuation allowance for our net deferred tax asset associated with our U.S. operations.  The provision (benefit) for taxes on U.S. operations for the second quarters and first six months of 2014 and 2013 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 for the second quarter and first six months of 2014 by $68 million ($0.06 per diluted share) and by $144 million ($0.12 per diluted share), respectively.

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 judgments.

	(1) We have the obligation or option to pay cash for the aggregate amount due upon conversion for all of our convertible notes. Since it is our current intent to settle in cash the principal amount of all of our convertible notes upon conversion, the dilutive effect of such notes on earnings per share is computed under the treasury stock method.
	(2) Since the closing price of our common stock for at least 20 trading days in the 30 trading day period ending on December 31, 2013 exceeded 130% of the initial conversion price per share, holders have the right to convert their notes at any time during the calendar quarter ended March 31, 2014.
	(3) As a result of these notes being convertible at the option of the holder through March 31, 2014, and because the terms of these notes would require us to pay cash for the principal amount of any converted notes, amounts are classified as current.

(1) We have the obligation or option to pay cash for the aggregate amount due upon conversion for all of our convertible notes. Since it is our current intent to settle in cash the principal amount of all of our convertible notes upon conversion, the dilutive effect of such notes on earnings per share is computed under the treasury stock method.

[2]

(3) As a result of these notes being convertible at the option of the holder through March 31, 2014, and because the terms of these notes would require us to pay cash for the principal amount of any converted notes, amounts are classified as current.

[3]

(2) Since the closing price of our common stock for at least 20 trading days in the 30 trading day period ending on December 31, 2013 exceeded 130% of the initial conversion price per share, holders have the right to convert their notes at any time during the calendar quarter ended March 31, 2014.

[4]

(3)B The original principal amount of $820 million accretes up to $917 million in November 2028 and $1,025 million at maturity in 2043.

[5]

(1)B Holders have the right to convert all or a portion of their notes at a date or dates earlier than the contractual maturity if, during any calendar quarter, the closing price of our common stock for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is more than 130% of the initial conversion price.

[6]

(2)B Based on our closing share price of $24.19 as of FebruaryB 27, 2014.

[1]	Settlement in cash on the respective expiration dates would result in us receiving an amount ranging from zero, if the market price per share of our common stock is at or below the respective low strike price, to the respective maximum amount if the market price per share of our common stock is at or above the respective high cap price. If share settlement were elected, the number of shares repurchased would be determined by the value of the capped calls at the time of settlement divided by the share price on the settlement date. Settlement of the capped calls prior to the expiration dates may be for an amount less than the maximum value at expiration.
[2]	Initial strike prices are subject to certain adjustments.
