	Organization and Summary of Significant Accounting Policies
	Organization
	These interim Condensed Consolidated Financial Statements are unaudited but reflect, in the opinion of management, all adjustments, consisting of normal recurring adjustments and accruals, necessary to present fairly the financial position of SanDisk Corporation and its subsidiaries (the “Company”) as of June 29, 2014, the Condensed Consolidated Statements of Operations and the Condensed Consolidated Statements of Comprehensive Income for the three and six months ended June 29, 2014 and June 30, 2013, and the Condensed Consolidated Statements of Cash Flows for the six months ended June 29, 2014 and June 30, 2013. Certain information and footnote disclosures normally included in financial statements prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) have been omitted in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). These Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s most recent Annual Report on Form 10-K filed with the SEC on February 21, 2014. The results of operations for the three and six months ended June 29, 2014 are not necessarily indicative of the results to be expected for the entire fiscal year.
	Basis of Presentation. The Company’s fiscal year ends on the Sunday closest to December 31 and its fiscal quarters consist of 13 weeks. The second quarters of fiscal years 2014 and 2013 ended on June 29, 2014 and June 30, 2013, respectively. For accounting and disclosure purposes, the exchange rates of 101.41, 104.94 and 99.07 at June 29, 2014, December 29, 2013 and June 30, 2013, respectively, were used to convert Japanese yen to U.S. dollars. Throughout the Notes to Condensed Consolidated Financial Statements, unless otherwise indicated, references to Net income refer to Net income attributable to common stockholders.
	Organization and Nature of Operations. The Company was incorporated in the State of Delaware on June 1, 1988. The Company designs, develops, markets and manufactures data storage solutions in a variety of form factors using its flash memory, controller, firmware and software technologies. The Company operates in one segment, flash memory storage products.
	Principles of Consolidation. The Condensed Consolidated Financial Statements include the accounts of the Company and its majority-owned subsidiaries. All intercompany balances and transactions have been eliminated. Non-controlling interest represents the minority shareholders’ proportionate share of the net assets and results of operations of the Company’s majority-owned subsidiaries. The Condensed Consolidated Financial Statements also include the results of companies acquired by the Company from the date of each acquisition.
	Use of Estimates. The preparation of Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. The estimates and judgments affect the reported amounts of assets, liabilities, revenue, expenses and related disclosure of contingent liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to customer programs and incentives, intellectual property claims, product returns, allowance for doubtful accounts, inventory valuation and related reserves, valuation and impairments of marketable securities and investments, valuation and impairments of goodwill and long-lived assets, income taxes, warranty obligations, restructurings, contingencies, share‑based compensation and litigation. The Company bases its estimates on historical experience and on other assumptions that its management believes are reasonable under the circumstances. These estimates form the basis for making judgments about the carrying value of assets and liabilities when those values are not readily apparent from other sources. Actual results could materially differ from these estimates.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued accounting guidance “Revenue from Contracts with Customers.” Under this guidance, an entity is required to recognize revenue upon transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. As such, an entity will need to use more judgment and make more estimates than under the current guidance. This standard becomes effective and will be adopted in the first quarter of fiscal year 2017 with early adoption not permitted. Under our application of the existing guidance, sales made to distributors and retailers are generally deferred until the distributors or retailers sell the merchandise to their end customer. Under the new standard, sales made to distributors and retailers may be recognized upon transfer of inventory to the distributor or retailer resulting in earlier revenue recognition than per existing guidance with additional use of estimation. In addition, the timing of our revenue relating to the licensing of our intellectual property could materially change. The Company is currently evaluating the appropriate transition method and any further impact of this guidance on its consolidated financial statements and related disclosures.
	In April 2014, the FASB issued accounting guidance “Presentation of Financial Statements and Property, Plant, and Equipment.” This new standard raises the threshold for a disposal transaction to qualify as a discontinued operation and requires additional disclosures about discontinued operations and disposals of individually significant components that do not qualify as discontinued operations. This standard is effective prospectively for all disposals of components that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted for new disposals (or new classifications as held for sale) that have not previously been reported in the financial statements. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements and related disclosures, if any, and will determine whether to adopt this guidance in the third quarter of fiscal year 2014.

	The gross unrealized loss related to these securities was due primarily to changes in interest rates. The gross unrealized loss on all available-for-sale fixed income securities at June 29, 2014 was considered temporary in nature. Factors considered in determining whether a loss is temporary include the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the investee, and the Company’s intent and ability to hold an investment for a period of time sufficient to allow for any anticipated recovery in market value. For debt security investments, the Company considered additional factors including the Company’s intent to sell the investments or whether it is “more likely than not” the Company will be required to sell the investments before the recovery of its amortized cost.

Derivative Instruments, Gain (Loss)	'
Derivative Instruments and Hedging Activities Disclosure [Text Block]	'
	Derivatives and Hedging Activities
	The Company uses derivative instruments primarily to manage exposures to foreign currency. The Company’s primary objective in holding derivative instruments is to reduce the volatility of earnings and cash flows associated with changes in foreign currency. The program is not designated for trading or speculative purposes. The Company’s derivative instruments expose the Company to credit risk to the extent that the counterparties may be unable to meet the terms of the agreement. The Company seeks to mitigate such risk by limiting its counterparties to major financial institutions and by spreading the risk across several major financial institutions. In addition, the potential risk of loss with any one counterparty resulting from this type of credit risk is monitored by the Company on an ongoing basis.
	The Company recognizes derivative instruments as either assets or liabilities on the balance sheet at fair value and provides qualitative disclosures about objectives and strategies for using derivative instruments, quantitative disclosures about fair value amounts of gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. Changes in fair value (i.e., gains or losses) of the derivatives are recorded as cost of revenue or other income (expense), or as other comprehensive income (“OCI”). Under certain provisions and conditions within agreements with counterparties to the Company’s foreign exchange forward contracts, subject to applicable requirements, the Company has the right of set-off associated with the Company’s foreign exchange forward contracts and is allowed to net settle transactions of the same currency with a single net amount payable by one party to the other. The Company does not offset or net the fair value amounts of derivative instruments in its Condensed Consolidated Balance Sheets and separately discloses the gross fair value amounts of the derivative instruments as either assets or liabilities.
	Cash Flow Hedges. The Company uses foreign exchange forward contracts designated as cash flow hedges to hedge a portion of future forecasted wafer purchases and research and development (“R&D”) expenses in Japanese yen. The gain or loss on the effective portion of a cash flow hedge is initially reported as a component of accumulated OCI (“AOCI”) and subsequently reclassified into cost of revenue or R&D expense in the same period or periods in which the cost of revenue or R&D expense are recognized, or reclassified into other income (expense) if the hedged transaction becomes probable of not occurring. Any gain or loss after a hedge is no longer designated, because it is no longer probable of occurring or it is related to an ineffective portion of a cash flow hedge, as well as any amount excluded from the Company’s hedge effectiveness, is recognized immediately as other income (expense). As of June 29, 2014, the notional amount and unrealized loss on the effective portion of the Company’s outstanding foreign exchange forward contracts to purchase Japanese yen that are designated as cash flow hedges are shown in both Japanese yen (in billions) and U.S. dollar (in thousands), based upon the exchange rate as of June 29, 2014, as follows:
		Notional Amount						Unrealized Loss
		(Japanese yen)			(U.S. dollar)			(U.S. dollar)
	Foreign exchange forward contracts	¥	48.8		$	481,350		$	(5,932	)
	As of June 29, 2014, the maturities of these contracts were 12 months or less.
	Other Derivatives. Other derivatives that are non-designated consist primarily of foreign exchange forward contracts to minimize the risk associated with the foreign exchange effects of revaluing monetary assets and liabilities. Monetary assets and liabilities denominated in foreign currencies and the associated outstanding foreign exchange forward contracts were marked-to-market at June 29, 2014 with realized and unrealized gains and losses included in other income (expense). As of June 29, 2014, the Company had foreign exchange forward contracts hedging exposures in European euros, British pounds and Japanese yen. Foreign exchange forward contracts were outstanding to buy and sell U.S. dollar-equivalents of approximately $127.5 million and $91.7 million in foreign currencies, respectively, based upon the exchange rates at June 29, 2014.
	The amounts in the tables below include fair value adjustments related to the Company’s own credit risk and counterparty credit risk.
	Fair Value of Derivative Contracts. Gross fair value of derivative contracts was as follows (in thousands):

	Foreign exchange forward contracts not designated	320			7,366			—			—
	Total derivatives	$	7,358		$	45,741		$	—		$	118
	As of June 29, 2014, the potential effect of rights of set-off associated with the above foreign exchange forward contracts would result in a net derivative assets balance of $1.1 million and a net derivative liabilities balance of $6.7 million. As of December 29, 2013, the potential effect of rights of set-off would result in a net derivative liabilities balance of $45.2 million and an immaterial net derivative asset balance.
	Foreign Exchange Forward Contracts Designated as Cash Flow Hedges. All designated cash flow derivative contracts were considered effective for the three and six months ended June 29, 2014 and June 30, 2013. The impact of the effective portion of designated cash flow derivative contracts on the Company’s results of operations was as follows (in thousands):

	Foreign exchange forward contracts designated as cash flow hedges relate to forecasted wafer purchases and R&D expenses in Japanese yen. Gains and losses associated with foreign exchange forward contracts designated as cash flow hedges are expected to be recorded in cost of revenue for wafer purchases or R&D expense when reclassified out of AOCI. The Company expects to realize the majority of the AOCI balance related to foreign exchange contracts within the next twelve months.

The majority of the Company’s products have a warranty of five years or less, with a small number of products having a warranty ranging up to ten years or more. For warranties ten years or greater, including lifetime warranties, the Company uses the estimated useful life of the product to calculate the warranty exposure. A provision for the estimated future cost related to warranty expense is recorded at the time of customer invoice. The Company’s warranty liability is affected by customer and consumer returns, product failures, number of units sold and repair or replacement costs incurred. Should actual product failure rates, or repair or replacement costs, differ from the Company’s estimates, increases or decreases to its warranty liability would be required.

	1.5% Convertible Senior Notes Due 2017. In August 2010, the Company issued and sold $1.0 billion in aggregate principal amount of 1.5% Convertible Senior Notes due August 15, 2017 (“1.5% Notes due 2017”) at par. The 1.5% Notes due 2017 may be converted, under certain circumstances described below, based on an initial conversion rate of 19.0931 shares of common stock per $1,000 principal amount of notes (which represents an initial conversion price of approximately $52.37 per share). The 1.5% Notes due 2017 contain provisions where the conversion rate and conversion price are adjusted if the Company pays a cash dividend or makes a distribution to all or substantially all holders of its common stock. Accordingly, as of June 29, 2014, the conversion rate was adjusted for dividends paid to date to 19.3448 shares of common stock per $1,000 principal amount of notes (which represents a conversion price of approximately $51.69 per share). The net proceeds to the Company from the sale of the 1.5% Notes due 2017 were $981.0 million.
	The Company separately accounts for the liability and equity components of the 1.5% Notes due 2017. The principal amount of the liability component of $706.0 million as of the date of issuance was recognized at the present value of its cash flows using a discount rate of 6.85%, the Company’s borrowing rate at the date of the issuance for a similar debt instrument without the conversion feature. As of June 29, 2014, after recognition of $149.1 million in Convertible short-term debt conversion obligation, the carrying value of the equity component was $144.9 million.
	The following table presents the amount of interest cost recognized relating to the contractual interest coupon, amortization of bond issuance costs and amortization of the bond discount on the liability component of the 1.5% Notes due 2017 (in thousands):
		Three months ended						Six months ended
		June 29,			June 30,			June 29,		June 30,
		2014			2013			2014		2013
	Contractual interest coupon	$	3,750		$	3,750		$	7,500	$	7,500

	Amortization of bond discount	10,498			9,802			20,690		19,321
	Total interest cost recognized	$	14,914		$	14,218		$	29,523	$	28,154
	The effective interest rate on the liability component of the 1.5% Notes due 2017 was 6.85% for each of the three and six months ended June 29, 2014 and June 30, 2013. The remaining unamortized bond discount of $149.1 million as of June 29, 2014 will be amortized over the remaining life of the 1.5% Notes due 2017, which is approximately 3.1 years.
	The conversion provision of the 1.5% Notes due 2017 allows the holders the option to convert their notes during the following calendar quarter if the Company’s stock price exceeds 130% of the conversion price of the 1.5% Notes due 2017 for at least 20 trading days during the last 30 consecutive trading days of the current calendar quarter. The conversion threshold was met during the calendar quarter ended June 30, 2014 and the 1.5% Notes due 2017 are convertible at the holders’ option beginning on July 1, 2014 and ending September 30, 2014. As such, the carrying value of the 1.5% Notes due 2017 was classified as a current liability and the difference between the principal amount payable in cash upon conversion and the carrying value of the 1.5% Notes due 2017 was reclassified from Stockholders’ equity to Convertible short-term debt conversion obligation on the Company’s Condensed Consolidated Balance Sheet as of June 29, 2014, and will remain so while the notes are convertible. The determination of whether or not the 1.5% Notes due 2017 are convertible must continue to be performed on a calendar-quarter basis. Consequently, the 1.5% Notes due 2017 may be reclassified as long-term debt if the conversion threshold is not met in future quarters. Upon conversion of any of the 1.5% Notes due 2017, the Company will deliver cash up to the principal amount of the 1.5% Notes due 2017 and shares of the Company’s common stock with respect to any conversion value greater than the principal amount of the 1.5% Notes due 2017. Based on the closing price of the Company’s common stock of $102.74 on June 29, 2014, if all of the 1.5% Notes due 2017 were converted, it would result in 9.6 million shares being distributed to the holders. As of June 29, 2014, no 1.5% Notes due 2017 had been converted.
	Concurrent with the issuance of the 1.5% Notes due 2017, the Company entered into a convertible bond hedge transaction in which counterparties initially agreed to sell to the Company up to approximately 19.1 million shares of the Company’s common stock, which is the number of shares initially issuable upon conversion of the 1.5% Notes due 2017 in full, at a price of $52.37 per share. The 1.5% Notes due 2017 contain provisions where the number of shares to be sold under the convertible bond hedge transaction and the conversion price will be adjusted if the Company pays a cash dividend or makes a distribution to all or substantially all holders of its common stock. After adjusting for the dividends paid through June 29, 2014, the counterparties may acquire up to approximately 19.3 million shares of the Company’s common stock, which is the number of shares issuable upon conversion of the 1.5% Notes due 2017 in full, at a price of $51.69 per share. This convertible bond hedge transaction will be settled in net shares and will terminate upon the earlier of the maturity date of the 1.5% Notes due 2017 or the first day that none of the 1.5% Notes due 2017 remain outstanding due to conversion or otherwise. As of June 29, 2014, the Company had not purchased any shares under this convertible bond hedge agreement. Settlement of the convertible bond hedge in net shares, based on the number of shares issuable upon conversion of the 1.5% Notes due 2017, on the expiration date would result in the Company receiving net shares equivalent to the number of shares issuable by the Company upon conversion of the 1.5% Notes due 2017.
	In addition, concurrent with the issuance of the 1.5% Notes due 2017, the Company sold warrants to acquire up to approximately 19.1 million shares of its common stock at an exercise price of $73.3250 per share. The 1.5% Notes due 2017 contain provisions whereby the number of shares to be acquired under the warrants and the strike price are adjusted if the Company pays a cash dividend or makes a distribution to all or substantially all holders of its common stock. After adjusting for the dividends paid through June 29, 2014, holders of the warrants may acquire up to approximately 19.3 million shares of the Company’s common stock at a strike price of $72.3712 per share. The warrants mature on 40 different dates from November 13, 2017 through January 10, 2018 and are exercisable at the maturity date. At each maturity date, the Company may, at its option, elect to settle the warrants on a net share basis. As of June 29, 2014, the warrants had not been exercised and remain outstanding.
	0.5% Convertible Senior Notes Due 2020. In October 2013, the Company issued and sold $1.5 billion in aggregate principal amount of 0.5% Convertible Senior Notes due October 15, 2020 (the “0.5% Notes due 2020”) at par. The 0.5% Notes due 2020 may be converted, under certain circumstances described below, based on an initial conversion rate of 10.8470 shares of common stock per $1,000 principal amount of notes (which represents an initial conversion price of approximately $92.19 per share). The 0.5% Notes due 2020 contain provisions where the conversion rate and conversion price are adjusted if the Company pays a cash dividend greater than a regular quarterly cash dividend of $0.225 per share or makes a distribution to all or substantially all holders of its common stock. As of June 29, 2014, no adjustment has been made to the conversion rate or the conversion price. The net proceeds to the Company from the sale of the 0.5% Notes due 2020 were approximately $1.48 billion.
	The Company separately accounts for the liability and equity components of the 0.5% Notes due 2020. The principal amount of the liability component of $1.15 billion as of the date of issuance was recognized at the present value of its cash flows using a discount rate of 4.43%, the Company’s borrowing rate at the date of the issuance for a similar debt instrument without the conversion feature. As of June 29, 2014, the carrying value of the equity component of $352.0 million was unchanged from the date of issuance.
	The following table presents the amount of interest cost recognized relating to the contractual interest coupon, amortization of bond issuance costs and amortization of the bond discount on the liability component of the 0.5% Notes due 2020 (in thousands):
		Three months ended			Six months ended
		June 29, 2014			June 29, 2014

	Amortization of bond discount	10,627			21,398
	Total interest cost recognized	$	13,140		$	26,445
	The effective interest rate on the liability component of the 0.5% Notes due 2020 was 4.43% for the three and six months ended June 29, 2014. The remaining unamortized bond discount of $322.7 million as of June 29, 2014 will be amortized over the remaining life of the 0.5% Notes due 2020, which is approximately 6.3 years.
	Concurrent with the issuance of the 0.5% Notes due 2020, the Company entered into a convertible bond hedge transaction in which counterparties agreed to sell to the Company up to approximately 16.3 million shares of the Company’s common stock, which is the number of shares issuable upon conversion of the 0.5% Notes due 2020 in full, at a price of $92.19 per share. The 0.5% Notes due 2020 contain provisions where the number of shares to be sold under the convertible bond hedge transaction and the conversion price will be adjusted if the Company pays a cash dividend greater than a regular quarterly cash dividend of $0.225 per share or makes a distribution to all or substantially all holders of its common stock. This convertible bond hedge transaction will be settled in net shares and will terminate upon the earlier of the maturity date of the 0.5% Notes due 2020 or the first day that none of the 0.5% Notes due 2020 remain outstanding due to conversion or otherwise.

	In addition, concurrent with the issuance of the 0.5% Notes due 2020, the Company sold warrants to acquire up to approximately 16.3 million shares of its common stock at an exercise price of $122.9220 per share. The 0.5% Notes due 2020 contain provisions whereby the number of shares to be acquired under the warrants and the strike price are adjusted if the Company pays a cash dividend greater than a regular quarterly cash dividend of $0.225 per share or makes a distribution to all or substantially all holders of its common stock. The warrants mature on 40 different dates from January 13, 2021 through March 11, 2021 and are exercisable at the maturity date. At each maturity date, the Company may, at its option, elect to settle the warrants on a net share basis. As of June 29, 2014, the warrants had not been exercised and remain outstanding.

	Share Repurchases
	In July 2013, the Company’s Board of Directors authorized a program to repurchase up to $2.5 billion of the Company’s common stock. As of June 29, 2014, the remaining authorization for share repurchases under the program was $1.59 billion. The share repurchase program will remain in effect until the available funds have been expended or the Company’s Board of Directors terminates the program. The Company’s prior share repurchase program, which was initially announced in October 2011 and authorized the repurchase over a five-year period of up to $1.25 billion, as increased by the Company’s Board of Directors in December 2012, was completed in the third quarter of fiscal year 2013.
	Under the Company’s share repurchase program, shares repurchased are recorded as a reduction to Capital in excess of par value and Retained earnings in the Company’s Condensed Consolidated Balance Sheets. The repurchases will be made from time to time in privately negotiated or open market transactions, including under plans complying with Rule 10b5-1 of the Securities Exchange Act, or in structured share repurchase programs, and may be made in one or more repurchases, in compliance with Rule 10b-18 of the Securities Exchange Act. Share repurchases are subject to market conditions, applicable legal requirements and other factors. The share repurchase program does not obligate the Company to acquire any specific number of common stock, or any shares at all, and may be suspended at any time at the Company’s discretion. As part of the share repurchase program, the Company has entered into, and may continue to enter into, structured share repurchase transactions with financial institutions. These agreements generally require that the Company make an up-front payment in exchange for the right to receive a fixed number of shares of its common stock upon execution of the agreement, with a potential increase or decrease in the number of shares at the end of the term of the agreement.
	In the third quarter of fiscal year 2013, under the Company’s share repurchase program, the Company entered into an accelerated share repurchase (“ASR”) agreement with a financial institution to purchase $1.0 billion of the Company’s common stock. In exchange for an up-front payment of $1.0 billion, the financial institution committed to deliver shares during the ASR’s purchase period, which ended on April 8, 2014. During the third quarter of fiscal year 2013, 14.5 million shares were initially delivered to the Company under this ASR agreement. The up-front payment of $1.0 billion was accounted for as a reduction to Stockholders’ equity in the Company’s Condensed Consolidated Balance Sheet. In April 2014, the ASR was settled and the Company received an additional 0.6 million shares from the financial institution for a total of 15.1 million shares, which resulted in a volume-weighted-average price of $66.07 per share.
	The Company reflected the ASR as a repurchase of common stock for purposes of calculating earnings per share and as a forward contract indexed to its own common stock. The forward contract met all of the applicable criteria for equity classification, and therefore, was not accounted for as a derivative instrument.
	Under the Company’s share repurchase program, since the fourth quarter of fiscal year 2011 through June 29, 2014, the Company spent an aggregate $2.16 billion to repurchase 35.0 million shares. Included in the aggregate repurchase activity are 4.0 million shares that were repurchased for an aggregate amount of $341.5 million during the six months ended June 29, 2014. In addition to repurchases under the Company’s share repurchase program, during the six months ended June 29, 2014, the Company spent $29.9 million to settle employee tax withholding obligations due upon the vesting of restricted stock units (“RSUs”) and withheld an equivalent value of shares from the shares provided to the employees upon vesting.

Share-Based Compensation	'
	Share-based Benefit Plans
	Share-based Plans. The Company has a share-based compensation program that provides its Board of Directors with broad discretion in creating equity incentives for employees, officers, non-employee board members and non-employee service providers. This program includes incentive and non-statutory stock option awards, stock appreciation rights (“SARs”), RSUs, performance-based cash bonus awards for Section 16 executive officers and an automatic grant program for non-employee board members pursuant to which such individuals will receive option grants or other stock awards at designated intervals over their period of board service. These awards are granted under various programs, all of which are stockholder approved. Stock option awards generally vest as follows: 25% of the shares vest on the first anniversary of the vesting commencement date and the remaining 75% vest proportionately each quarter over the next 12 quarters of continued service. RSUs generally vest in equal annual installments over a four-year period. Initial grants to non-employee board members under the automatic grant program vest in equal annual installments over a four-year period and subsequent grants to non-employee board members generally vest over a one-year period in accordance with the specific vesting provisions set forth in that program. Additionally, the Company has an Employee Stock Purchase Plan (“ESPP”) that allows employees to purchase shares of common stock at 85% of the fair market value at the subscription date or the date of purchase, whichever is lower.

	Stock Options and SARs. A summary of stock option and SARs activities under all of the Company’s share-based compensation plans as of June 29, 2014 and changes during the six months ended June 29, 2014 are presented below (in thousands, except for weighted-average exercise price and remaining contractual term):
		Shares			Weighted-Average Exercise Price				Weighted-Average Remaining Contractual Term (Years)		Aggregate Intrinsic Value

	Options and SARs exercisable at June 29, 2014	1,849			35.62				3.2		124,068
	At June 29, 2014, the total unrecognized compensation cost related to stock options, net of estimated forfeitures, was approximately $47.5 million, and this amount is expected to be recognized over a weighted-average period of approximately 2.4 years. As of June 29, 2014, the Company had fully expensed all of its SARs awards.
	Restricted Stock Units. RSUs are settled in shares of the Company’s common stock upon vesting on a one-for-one basis. Typically, vesting of RSUs is subject to the employee’s continuing service to the Company. The cost of these awards is determined using the fair value of the Company’s common stock on the date of grant, and compensation is recognized on a straight-line basis over the requisite vesting period.
	A summary of the changes in RSUs outstanding under the Company’s share-based compensation plans during the six months ended June 29, 2014 is presented below (in thousands, except for weighted-average grant date fair value):

	Provision for Income Taxes
	The following table presents the provision for income taxes and the effective tax rate (in thousands, except percentages):
		Three months ended						Six months ended
		June 29,			June 30,			June 29,			June 30,
		2014			2013			2014			2013
	Provision for income taxes	$	129,131		$	121,668		$	269,722		$	189,333
	Effective tax rate	32		%	31.7		%	33.2		%	30.7		%
	The provision for income taxes for the three and six months ended June 29, 2014 differs from the U.S. statutory tax rate of 35% due primarily to the tax impact of earnings from foreign operations, state taxes, non-deductibility of certain share-based compensation and tax-exempt interest income. Earnings and taxes resulting from foreign operations are largely attributable to the Company’s Irish, Chinese, Israeli and Japanese entities. Earnings in these countries where tax rates are lower than the U.S. notional rate contributed to the majority of the difference between the rate of the Company’s tax provision and the U.S. statutory tax rate. The higher effective tax rate for the six months ended June 29, 2014, compared to the same period in fiscal year 2013, is attributable to the federal R&D tax credit not being extended as of June 29, 2014, while the June 30, 2013 effective tax rate includes both the 2013 federal R&D credit and retroactive inclusion of the 2012 federal R&D tax credit, and changes in the composition of operating income by tax jurisdiction. As of June 29, 2014, the Company believes that most of its deferred tax assets are more likely than not to be realized, except for certain loss and credit carry forwards in certain U.S. and foreign tax jurisdictions.
	Unrecognized tax benefits were $185.0 million and $185.3 million as of June 29, 2014 and December 29, 2013, respectively. Unrecognized tax benefits that would impact the effective tax rate in the future were approximately $85.4 million at June 29, 2014. Interest and penalties included in the income tax expense for the three and six months ended June 29, 2014 and June 30, 2013 were immaterial. It is reasonably possible that within the next 12 months, unrecognized tax benefits could decrease by up to $80.0 million as a result of potential settlements of tax authority examinations and could decrease by up to $10.2 million as a result of the expiration of statutes of limitation.
	The Company is subject to U.S. federal income tax as well as income taxes in multiple state and foreign jurisdictions. In February 2012, the Internal Revenue Service (“IRS”) completed its field audit of the Company’s federal income tax returns for fiscal years 2005 through 2008 and issued the Revenue Agent’s Report. The most significant proposed adjustments are comprised of related party transactions between SanDisk Corporation and its foreign subsidiaries. The Company is contesting these adjustments through the IRS Appeals Office and cannot predict when a resolution will be reached.
	The Company strongly believes the IRS’s position regarding the intercompany transactions is inconsistent with applicable tax laws, judicial precedents and existing Treasury regulations, and that the Company’s previously reported income tax provisions for the years in question are appropriate. The Company believes that an adequate provision has been made for the adjustments from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner that is not consistent with management’s expectations, the Company could be required to adjust its provision for income tax in the period such resolution occurs.
	The IRS recently initiated an examination of the Company’s federal income tax returns for fiscal years 2009 through 2011. The Company does not expect a resolution of this audit to be reached during the next twelve months. In addition, the Company is currently under audit by various state and international tax authorities. The Company cannot reasonably estimate the outcome of these examinations, or provide assurance that the outcome of these examinations will not materially harm the Company’s financial position, results of operations or liquidity.

	Flash Ventures
	Flash Ventures, the Company’s business ventures with Toshiba Corporation (“Toshiba”), consists of three separate legal entities: Flash Partners Ltd., Flash Alliance Ltd. and Flash Forward Ltd. The Company has a 49.9% ownership interest in each of these entities and Toshiba owns 50.1% of each of these entities. Through these ventures, the Company and Toshiba have collaborated in the development and manufacture of NAND flash memory products which are manufactured by Toshiba at its wafer fabrication facility located in Yokkaichi, Japan, using semiconductor manufacturing equipment owned or leased by Flash Ventures. Flash Ventures purchase wafers from Toshiba at cost and then resell those wafers to the Company and Toshiba at cost plus a markup. The Company accounts for its ownership position in each Flash Ventures entity under the equity method of accounting. The Company is committed to purchase its provided three-month forecast of Flash Ventures’ NAND wafer supply, which generally equals 50% of Flash Ventures’ output. The Company is not able to estimate its total wafer purchase commitment obligation beyond its rolling three-month purchase commitment because the price is determined by reference to the future cost of producing the semiconductor wafers. In addition, the Company is committed to fund 49.9% of Flash Ventures’ costs to the extent that Flash Ventures’ revenue from wafer sales to the Company and Toshiba are insufficient to cover these costs.
	Flash Partners. Flash Partners Ltd. (“Flash Partners”) was formed in fiscal year 2004. NAND flash memory products provided to the Company by this venture are manufactured by Toshiba at its 300-millimeter wafer fabrication facility (“Fab 3”) located in Yokkaichi, Japan. As of June 29, 2014, the Company had notes receivable from Flash Partners of $29.6 million, denominated in Japanese yen. These notes are secured by the equipment purchased by Flash Partners with the note proceeds. The Company also has guarantee obligations to Flash Partners; see “Off-Balance Sheet Liabilities.” At June 29, 2014 and December 29, 2013, the Company had an equity investment in Flash Partners of $197.4 million and $190.7 million, respectively, denominated in Japanese yen, adjusted by $24.0 million and $17.3 million, respectively, of cumulative translation adjustments recorded in AOCI. The Company records basis adjustments to its equity in earnings from Flash Partners that relate to the difference between the basis in the Company’s equity investment compared to the historical basis of the assets recorded by Flash Partners. In the three and six months ended June 29, 2014, the Company recorded no basis adjustments to its equity in earnings from Flash Partners. In the three and six months ended June 30, 2013, the Company recorded a basis adjustment of $0.3 million and $0.6 million, respectively, to its equity earnings from Flash Partners. Flash Partners’ share of the Fab 3 fabrication facility is fully equipped.
	Flash Alliance. Flash Alliance Ltd. (“Flash Alliance”) was formed in fiscal year 2006. NAND flash memory products provided to the Company by this venture are manufactured by Toshiba at its 300-millimeter wafer fabrication facility (“Fab 4”) located in Yokkaichi, Japan. As of June 29, 2014, the Company had notes receivable from Flash Alliance of $320.5 million, denominated in Japanese yen. These notes are secured by the equipment purchased by Flash Alliance with the note proceeds. The Company also has guarantee obligations to Flash Alliance; see “Off-Balance Sheet Liabilities.” At June 29, 2014 and December 29, 2013, the Company had an equity investment in Flash Alliance of $294.7 million and $284.0 million, respectively, denominated in Japanese yen, adjusted by $1.2 million and ($8.7) million, respectively, of cumulative translation adjustments recorded in AOCI. The Company records basis adjustments to its equity in earnings from Flash Alliance that relate to the difference between the basis in the Company’s equity investment compared to the historical basis of the assets recorded by Flash Alliance. In the three and six months ended June 29, 2014, the Company recorded no basis adjustments to its equity in earnings from Flash Alliance. In the three and six months ended June 30, 2013, the Company recorded a basis adjustment of $2.1 million and $5.0 million, respectively, to its equity earnings from Flash Alliance. Flash Alliance’s share of the Fab 4 fabrication facility is fully equipped.
	Flash Forward. Flash Forward Ltd. (“Flash Forward”) was formed in fiscal year 2010. NAND flash memory products provided to the Company by this venture are manufactured by Toshiba at its 300-millimeter wafer fabrication facility (“Fab 5”) located in Yokkaichi, Japan. Fab 5 is to be built in two phases. Within the second half of fiscal year 2014, Phase 1 of the building is expected to be fully utilized with the addition of equipment including 1Y‑nanometer technology transition tools, development tools for 3D NAND, and tools for a planned increase in Flash Ventures wafer capacity of less than 5%. The Company and Toshiba each retain some flexibility as to the extent and timing of each party’s respective fab capacity ramps. The Phase 2 shell of the Fab 5 wafer fabrication facility is nearly complete and equipment installation will begin in the third quarter of fiscal year 2014. The Phase 2 shell is currently intended to be used primarily for technology transition of the existing Flash Ventures wafer capacity to 1Y‑nanometer and 1Z‑nanometer technology nodes and for a 3‑dimensional NAND (“3D NAND”) pilot line.
	As of June 29, 2014, the Company had notes receivable from Flash Forward of $239.1 million, denominated in Japanese yen. These notes are secured by the equipment purchased by Flash Forward with the note proceeds. The Company also has guarantee obligations to Flash Forward; see “Off-Balance Sheet Liabilities.” At June 29, 2014 and December 29, 2013, the Company had an equity investment in Flash Forward of $93.8 million and $66.7 million, respectively, denominated in Japanese yen, adjusted by ($13.5) million and ($16.2) million, respectively, of cumulative translation adjustments recorded in AOCI.
	Inventory Purchase Commitments with Flash Ventures. Purchase orders placed under Flash Ventures for up to three months are binding and cannot be canceled. These outstanding purchase commitments are included as part of the total “Noncancelable production purchase commitments” in the “Contractual Obligations” table.
	Off-Balance Sheet Liabilities
	Flash Ventures. Flash Ventures sell and lease back from a consortium of financial institutions (“lessors”) a portion of their tools and have entered into equipment master lease agreements totaling 191.2 billion Japanese yen, or approximately $1.89 billion based upon the exchange rate at June 29, 2014. As of June 29, 2014, the total amount outstanding from these master leases was 118.9 billion Japanese yen, or approximately $1.17 billion based upon the exchange rate at June 29, 2014, of which the amount of the Company’s guarantee obligation of the Flash Ventures’ master lease agreements, which reflects future payments and any lease adjustments, was 59.4 billion Japanese yen, or approximately $586 million based upon the exchange rate at June 29, 2014.
	The master lease agreements contain customary covenants for Japanese lease facilities. In addition to containing customary events of default related to Flash Ventures that could result in an acceleration of Flash Ventures’ obligations, the master lease agreements contain an acceleration clause for certain events of default related to the Company as guarantor, including, among other things, the Company’s failure to maintain a minimum stockholders’ equity of at least $1.51 billion. As of June 29, 2014, Flash Ventures was in compliance with all of its master lease covenants, including the shareholders’ equity covenant with the Company’s stockholders’ equity at $7.15 billion as of June 29, 2014. If the Company’s stockholders’ equity falls below $1.51 billion, or other events of default occur, Flash Ventures would become non-compliant under its master equipment lease agreements and would be required to negotiate a resolution to the non-compliance to avoid acceleration of the obligations under such agreements. Such resolution could include, among other things, supplementary security to be supplied by the Company, as guarantor, or increased interest rates or waiver fees, should the lessors decide they need additional collateral or financial consideration under the circumstances. If a non-compliance event were to occur and if the Company failed to reach a resolution, the Company could be required to pay a portion or the entire outstanding lease obligations covered by its guarantees under such Flash Ventures master lease agreements.
	The following table details the Company’s portion of the remaining guarantee obligations under each of Flash Ventures’ master lease facilities (both initial and refinanced leases) in both Japanese yen (in billions) and U.S. dollar-equivalent (in thousands) based upon the exchange rate at June 29, 2014:

	Total guarantee obligations		$	424,387			$	161,679			$	586,066
	Guarantees
	Indemnification Agreements. The Company has agreed to indemnify suppliers and customers for alleged intellectual property infringement. The scope of such indemnity varies, but may, in some instances, include indemnification for damages and expenses, including attorneys’ fees. The Company may periodically engage in litigation as a result of these indemnification obligations. The Company’s insurance policies exclude coverage for third-party claims for patent infringement. Although the liability is not remote, the nature of the patent infringement indemnification obligations prevents the Company from making a reasonable estimate of the maximum potential amount it could be required to pay to its suppliers and customers. Historically, the Company has not made any significant indemnification payments under any such agreements. As of June 29, 2014, no amounts had been accrued in the accompanying Condensed Consolidated Financial Statements with respect to these indemnification guarantees.
	As permitted under Delaware law and the Company’s certificate of incorporation and bylaws, the Company has agreements, or has assumed agreements in connection with its acquisitions, whereby it indemnifies certain of its officers and employees, and each of its directors for certain events or occurrences while the officer, employee or director is, or was, serving at the Company’s or the acquired company’s request in such capacity. The term of the indemnification period is for the officer’s, employee’s or director’s lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is generally unlimited; however, the Company has a Director and Officer insurance policy that may reduce its exposure and enable it to recover all or a portion of any future amounts paid. As a result of its insurance coverage, the Company believes the estimated fair value of these indemnification agreements is minimal. The Company has no liabilities recorded for these agreements as of June 29, 2014 or December 29, 2013, as these liabilities are not reasonably estimable even though liabilities under these agreements are not remote.
	The Company and Toshiba have agreed to mutually contribute to, and indemnify each other and Flash Ventures for, environmental remediation costs or liability resulting from Flash Ventures’ manufacturing operations in certain circumstances. The Company and Toshiba have also entered into a Patent Indemnification Agreement under which, in many cases, the Company will share in the expenses associated with the defense and cost of settlement associated with such claims. This agreement provides limited protection for the Company against third-party claims that NAND flash memory products manufactured and sold by Flash Ventures infringe third-party patents. The Company has not made any indemnification payments under any such agreements. As of June 29, 2014, no amounts have been accrued in the Company’s Condensed Consolidated Financial Statements with respect to these indemnification guarantees.
	Contractual Obligations and Off-Balance Sheet Arrangements
	The following tables summarize the Company’s contractual cash obligations, commitments and off-balance sheet arrangements at June 29, 2014, and the effect such obligations are expected to have on its liquidity and cash flows in future periods.

	(1)	Includes reimbursement for depreciation and lease payments on owned and committed equipment, funding commitments for loans and equity investments and reimbursement for other committed expenses. Funding commitments assume no additional operating lease guarantees; new operating lease guarantees can reduce funding commitments.
	(2)	In August 2010, the Company issued and sold $1.0 billion in aggregate principal amount of 1.5% Notes due 2017. The Company will pay cash interest on the outstanding notes at an annual rate of 1.5%, payable semi-annually on August 15 and February 15 of each year until August 15, 2017.
	(3)	In October 2013, the Company issued and sold $1.5 billion in aggregate principal amount of 0.5% Notes due 2020. The Company will pay cash interest on the outstanding notes at an annual rate of 0.5%, payable semi-annually on April 15 and October 15 of each year until October 15, 2020.
(4)	Includes Flash Ventures, related party vendors and other silicon source vendor purchase commitments.
(5)	Includes amounts denominated in a currency other than the U.S. dollar, which are subject to fluctuation in exchange rates prior to payment and have been translated using the exchange rate at June 29, 2014.
(6)	Excludes amounts related to the master lease agreements’ purchase option exercise price at final lease term.
The Company has excluded $198.9 million of unrecognized tax benefits (which includes penalties and interest) from the contractual obligation table above due to the uncertainty with respect to the timing of associated future cash flows at June 29, 2014. The Company is unable to make reasonably reliable estimates of the period of cash settlement with the respective taxing authorities.

	Flash Ventures with Toshiba. The Company owns 49.9% of each entity within Flash Ventures and accounts for its ownership position under the equity method of accounting. The Company’s obligations with respect to the Flash Ventures master lease agreements, take-or-pay supply arrangements and R&D cost sharing are described in Note 11, “Commitments, Contingencies and Guarantees.” The financial and other support provided by the Company in all periods presented was either contractually required or the result of a joint decision to expand wafer capacity, transition to new technologies or refinance existing equipment lease commitments. Flash Ventures are variable interest entities (“VIEs”). The Company evaluated whether it is the primary beneficiary of any of the entities within Flash Ventures for all periods presented and determined that it is not the primary beneficiary of any of the entities within Flash Ventures because it does not have a controlling financial interest in any of those entities. In determining whether the Company is the primary beneficiary, the Company analyzed the primary purpose and design of Flash Ventures, the activities that most significantly impact Flash Ventures’ economic performance, and whether the Company had the power to direct those activities. The Company concluded, based upon its 49.9% ownership in Flash Ventures, the voting structure of Flash Ventures and the manner in which the day-to-day operations of Flash Ventures are conducted that the Company lacked the power to direct most of the activities that most significantly impact Flash Ventures’ economic performance.
	The Company purchased NAND flash memory wafers from Flash Ventures and made prepayments, investments and loans to Flash Ventures totaling $504.5 million and $964.7 million during the three and six months ended June 29, 2014, respectively. The Company received loan repayments from Flash Ventures of $87.9 million and $112.3 million during the three and six months ended June 29, 2014, respectively. The Company purchased NAND flash memory wafers from Flash Ventures and made prepayments, investments and loans to Flash Ventures totaling $455.4 million and $934.3 million during the three and six months ended June 30, 2013, respectively. The Company received loan repayments from Flash Ventures of $19.8 million and $73.4 million during the three and six months ended June 30, 2013, respectively. At June 29, 2014 and December 29, 2013, the Company had accounts payable balances due to Flash Ventures of $151.2 million and $146.0 million, respectively.
	The Company’s maximum reasonably estimable loss exposure (excluding lost profits), based upon the exchange rate at each respective balance sheet date, as a result of its involvement with Flash Ventures, is presented below (in millions).

	Litigation
	From time to time, the Company is involved in various litigation matters, including those described below, among others. The litigation proceedings in which the Company is involved from time to time may include matters such as intellectual property, antitrust, commercial, labor, class action and insurance disputes. The semiconductor industry is characterized by significant litigation seeking to enforce patent and other intellectual property rights. The Company has enforced, and likely will continue to enforce, its own intellectual property rights through litigation and related proceedings.
	In each case listed below where the Company is the defendant, the Company intends to vigorously defend the action. At this time, the Company does not believe it is reasonably possible that losses related to the litigation described below have occurred beyond the amounts, if any, which have been accrued. However, legal discovery and litigation is highly unpredictable and future legal developments may cause current estimates to change in future periods.
	Patent Infringement and Antitrust Litigation With Round Rock Research LLC. On October 27, 2011, in response to infringement allegations by Round Rock Research LLC (“Round Rock”), the Company filed a lawsuit against Round Rock in the U.S. District Court for the Northern District of California. The lawsuit seeks a declaratory judgment that twelve Round Rock patents are invalid and/or not infringed by flash memory products sold by the Company. Round Rock has since withdrawn its infringement allegations as to eight of the patents. The parties filed several motions for summary judgment directed to various claims and defenses. On June 13, 2014, the Company won multiple summary judgment motions, which included a ruling that it did not infringe two of the remaining four patents based on patent exhaustion because its memories were purchased from an authorized licensee and other rulings limiting the potential damages from the other two patents. On July 3, 2014, Round Rock dismissed the two remaining patents in the case in order to appeal the court’s summary judgment rulings. The court entered final judgment on July 3, 2014. On July 23, 2014, Round Rock filed a notice of appeal.
	On May 3, 2012, Round Rock filed an action in the U.S. District Court for the District of Delaware alleging that the Company infringed eleven patents, and subsequently filed an amended complaint alleging that the Company’s infringement was willful. The parties agreed to dismiss one patent from this Delaware lawsuit that was also being litigated in the California case described above. Trial is currently scheduled to begin on January 20, 2015.
	On March 19, 2014, the Company filed an action against Round Rock in the U.S. District Court for the District of Delaware for antitrust violations arising from Round Rock's acquisition of patents from Micron Technology, Inc. (“Micron”) and demand for royalties that are not reasonable and non-discriminatory for alleged infringement of patents that Round Rock claims are standards-essential. The Company alleges that Round Rock violated the antitrust laws by conspiring with Micron and violating commitments that Micron made to the standards-setting organization, JEDEC Solid State Technology Association. The antitrust case has been stayed until after the January 2015 trial in the patent case.
	Ritz Camera Federal Antitrust Class Action. On June 25, 2010, Ritz Camera & Image, LLC (“Ritz”) filed a complaint in the U.S. District Court for the Northern District of California (the “District Court”), alleging that the Company violated federal antitrust law by conspiring to monopolize and monopolizing the market for flash memory products. The lawsuit captioned Ritz Camera & Image, LLC v. SanDisk Corporation, Inc. and Eliyahou Harari, purports to be on behalf of direct purchasers of flash memory products sold by the Company and joint ventures controlled by the Company from June 25, 2006 through the present. The complaint alleges that the Company created and maintained a monopoly by fraudulently obtaining patents and using them to restrain competition and by allegedly converting other patents for its competitive use. On February 24, 2011, the District Court issued an Order granting in part and denying in part the Company’s motion to dismiss, which resulted in Dr. Harari being dismissed as a defendant. On September 19, 2011, the Company filed a petition for permission to file an interlocutory appeal in the U.S. Court of Appeals for the Federal Circuit (the “Federal Circuit”) for the portion of the District Court’s Order denying the Company’s motion to dismiss based on Ritz’s lack of standing to pursue Walker Process antitrust claims. On October 27, 2011, the District Court administratively closed the case pending the Federal Circuit’s ruling on the Company’s petition. On November 20, 2012, the Federal Circuit affirmed the District Court’s order denying SanDisk’s motion to dismiss. On December 2, 2012, the Federal Circuit issued its mandate returning the case to the District Court. Discovery is now open in the District Court. On February 20, 2013, Ritz filed a motion requesting that Albert Giuliano, the Chapter 7 Trustee of the Ritz bankruptcy estate, be substituted as the plaintiff in this case, which the District Court granted on July 5, 2013. On October 1, 2013, the District Court granted the Trustee’s motion for leave to file a third amended complaint, which adds CPM Electronics Inc. and E.S.E. Electronics, Inc. as named plaintiffs. Ritz has sought leave to file a fourth amended complaint, which would add a cause of action for attempted monopolization, add another named plaintiff and extend the class period to July 1997. The Company has filed a motion to dismiss the third amended complaint. The District Court has taken all of the motions under submission. The hearing on class certification is scheduled for November 14, 2014.
	Samsung Federal Antitrust Action Against Panasonic and SD‑3C. On July 15, 2010, Samsung Electronics Co., Ltd. (“Samsung”) filed an action in the U.S. District Court for the Northern District of California (the “District Court”) alleging various claims against Panasonic Corporation and Panasonic Corporation of North America (collectively, “Panasonic”) and SD‑3C, LLC (“SD‑3C”) under federal antitrust law pursuant to Sections 1 and 2 of the Sherman Act, and under California antitrust and unfair competition laws relating to the licensing practices and operations of SD‑3C. The complaint seeks an injunction against collection of Secure Digital (“SD”) card royalties, treble damages, restitution, pre- and post-judgment interest, costs, and attorneys’ fees, as well as a declaration that Panasonic and SD-3C engaged in patent misuse and that the patents subject to such alleged misuse should be held unenforceable. The Company is not named as a defendant in this case, but it established SD‑3C along with Panasonic and Toshiba, and the complaint includes various factual allegations concerning the Company. As a member of SD‑3C, the Company may be responsible for a portion of any monetary award. Other requested relief, including an injunction or declaration of patent misuse, could result in a loss of revenue to the Company. Defendants filed a motion to dismiss on September 24, 2010, and Samsung filed a First Amended Complaint (“FAC”) on October 14, 2010. On August 25, 2011, the District Court dismissed the patent misuse claim with prejudice but gave Samsung leave to amend its other claims. On January 3, 2012, the District Court granted defendants’ motion to dismiss Samsung’s complaint without leave to amend. Samsung appealed. On April 4, 2014, the U.S. Court of Appeals for the Ninth Circuit (the “Appeals Court”) issued a decision reversing the District Court’s dismissal on statute of limitations grounds and remanding the case to the District Court for further proceedings. The Appeals Court has denied defendants’ petition for rehearing.
	Federal Antitrust Class Action Against SanDisk, et al. On March 15, 2011, a putative class action captioned Oliver v. SD‑3C LLC, et al was filed in the U.S. District Court for the Northern District of California (the “District Court”) on behalf of a nationwide class of indirect purchasers of SD cards alleging various claims against the Company, SD‑3C, LLC (“SD‑3C”), Panasonic Corporation, Panasonic Corporation of North America, Toshiba and Toshiba America Electronic Components, Inc. under federal antitrust law pursuant to Section 1 of the Sherman Act, California antitrust and unfair competition laws, and common law. The complaint seeks an injunction of the challenged conduct, dissolution of “the cooperation agreements, joint ventures and/or cross-licenses alleged herein,” treble damages, restitution, disgorgement, pre- and post-judgment interest, costs, and attorneys’ fees. Plaintiffs allege that the Company (along with the other members of SD‑3C) conspired to artificially inflate the royalty costs associated with manufacturing SD cards in violation of federal and California antitrust and unfair competition laws, which in turn allegedly caused plaintiffs to pay higher prices for SD cards. The allegations are similar to, and incorporate by reference the complaint in the Samsung Electronics Co., Ltd. v. Panasonic Corporation; Panasonic Corporation of North America; and SD‑3C LLC described above. On May 21, 2012, the District Court granted Defendants’ motion to dismiss the complaint with prejudice. Plaintiffs appealed. On May 14, 2014, the appeals court issued a decision reversing the District Court’s dismissal on statute of limitations grounds and remanding the case to the District Court for further proceedings. Defendants timely filed a petition for rehearing with the appeals court. The parties are awaiting a ruling on the petition.
	Trade Secret Litigation Against SK Hynix, et al. On March 13, 2014, the Company filed a civil action in Santa Clara Superior Court in California against SK Hynix, Inc. (“SK Hynix”) and certain related entities (collectively, “defendants”) for trade secret misappropriation arising from the theft of trade secrets by a former employee of the Company and defendants’ wrongful receipt and use of such information. The lawsuit seeks damages, an injunction and other remedies. Additionally, in March 2014, SanDisk submitted a criminal complaint to the Tokyo Metropolitan Police Department against the former employee. On April 3, 2014, the former employee was indicted by the Tokyo District Public Prosecutor’s Office for theft of trade secrets.
	In June 2014, the Company moved for a preliminary injunction requiring SK Hynix to stop using any of the Company’s information received from the former employee and to return stolen Company material. On July 1, 2014, the court issued a preliminary injunction prohibiting SK Hynix from using or disclosing trade secret information that originated from materials taken by the former employee and ordering SK Hynix to provide certain information to the Company’s counsel to facilitate the identification of those documents taken by the former employee that are in SK Hynix’s possession. The order does not preclude SK Hynix from continuing to sell NAND flash products that it has already qualified for commercial sale. SK Hynix has filed a notice of appeal of the court’s preliminary injunction and also moved to stay enforcement of the order pending the appeal. On July 16, 2014, the court denied SK Hynix’s motion with respect to the portion of the order prohibiting use or disclosure of the trade secret information, but granted the motion to stay with respect to the other portion of the order.
	Federal Securities Class Action Against Fusion-io et al. Beginning on November 19, 2013, Fusion-io and certain of its officers (the “defendants”) were named in three putative class action lawsuits filed in the United States District Court for the Northern District of California (Denenberg v. Fusion-io, Inc. et al.; Miami Police Relief & Pension Fund v. Fusion-io, Inc. et al.; Marriott v. Fusion-io, Inc. et al.). Two of the complaints are allegedly brought on behalf of a class of purchasers of Fusion-io’s common stock between August 10, 2012 and October 23, 2013, and one is brought on behalf of a purported class of purchasers between January 25, 2012 and October 23, 2013. The complaints generally allege violations of the federal securities laws arising out of alleged misstatements or omissions by the defendants during the alleged class periods. The complaints seek, among other things, compensatory damages and attorneys’ fees and costs on behalf of the putative class. On June 10, 2014, the Court consolidated the cases, appointed a lead plaintiff, and ordered plaintiffs to file an amended consolidated complaint.

Organization and Nature of Operations	'
	Organization and Nature of Operations. The Company was incorporated in the State of Delaware on June 1, 1988. The Company designs, develops, markets and manufactures data storage solutions in a variety of form factors using its flash memory, controller, firmware and software technologies. The Company operates in one segment, flash memory storage products.
Basis of Presentation	'
	Basis of Presentation. The Company’s fiscal year ends on the Sunday closest to December 31 and its fiscal quarters consist of 13 weeks. The second quarters of fiscal years 2014 and 2013 ended on June 29, 2014 and June 30, 2013, respectively. For accounting and disclosure purposes, the exchange rates of 101.41, 104.94 and 99.07 at June 29, 2014, December 29, 2013 and June 30, 2013, respectively, were used to convert Japanese yen to U.S. dollars. Throughout the Notes to Condensed Consolidated Financial Statements, unless otherwise indicated, references to Net income refer to Net income attributable to common stockholders.
Consolidation, Policy	'
	Principles of Consolidation. The Condensed Consolidated Financial Statements include the accounts of the Company and its majority-owned subsidiaries. All intercompany balances and transactions have been eliminated. Non-controlling interest represents the minority shareholders’ proportionate share of the net assets and results of operations of the Company’s majority-owned subsidiaries. The Condensed Consolidated Financial Statements also include the results of companies acquired by the Company from the date of each acquisition.
Use of Estimates	'
	Use of Estimates. The preparation of Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. The estimates and judgments affect the reported amounts of assets, liabilities, revenue, expenses and related disclosure of contingent liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to customer programs and incentives, intellectual property claims, product returns, allowance for doubtful accounts, inventory valuation and related reserves, valuation and impairments of marketable securities and investments, valuation and impairments of goodwill and long-lived assets, income taxes, warranty obligations, restructurings, contingencies, share‑based compensation and litigation. The Company bases its estimates on historical experience and on other assumptions that its management believes are reasonable under the circumstances. These estimates form the basis for making judgments about the carrying value of assets and liabilities when those values are not readily apparent from other sources. Actual results could materially differ from these estimates.

	The Company recognizes derivative instruments as either assets or liabilities on the balance sheet at fair value and provides qualitative disclosures about objectives and strategies for using derivative instruments, quantitative disclosures about fair value amounts of gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. Changes in fair value (i.e., gains or losses) of the derivatives are recorded as cost of revenue or other income (expense), or as other comprehensive income (“OCI”). Under certain provisions and conditions within agreements with counterparties to the Company’s foreign exchange forward contracts, subject to applicable requirements, the Company has the right of set-off associated with the Company’s foreign exchange forward contracts and is allowed to net settle transactions of the same currency with a single net amount payable by one party to the other. The Company does not offset or net the fair value amounts of derivative instruments in its Condensed Consolidated Balance Sheets and separately discloses the gross fair value amounts of the derivative instruments as either assets or liabilities.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]	'
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	'
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued accounting guidance “Revenue from Contracts with Customers.” Under this guidance, an entity is required to recognize revenue upon transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. As such, an entity will need to use more judgment and make more estimates than under the current guidance. This standard becomes effective and will be adopted in the first quarter of fiscal year 2017 with early adoption not permitted. Under our application of the existing guidance, sales made to distributors and retailers are generally deferred until the distributors or retailers sell the merchandise to their end customer. Under the new standard, sales made to distributors and retailers may be recognized upon transfer of inventory to the distributor or retailer resulting in earlier revenue recognition than per existing guidance with additional use of estimation. In addition, the timing of our revenue relating to the licensing of our intellectual property could materially change. The Company is currently evaluating the appropriate transition method and any further impact of this guidance on its consolidated financial statements and related disclosures.
	In April 2014, the FASB issued accounting guidance “Presentation of Financial Statements and Property, Plant, and Equipment.” This new standard raises the threshold for a disposal transaction to qualify as a discontinued operation and requires additional disclosures about discontinued operations and disposals of individually significant components that do not qualify as discontinued operations. This standard is effective prospectively for all disposals of components that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted for new disposals (or new classifications as held for sale) that have not previously been reported in the financial statements. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements and related disclosures, if any, and will determine whether to adopt this guidance in the third quarter of fiscal year 2014.
