The Company and Basis of Presentation	'
	THE COMPANY AND BASIS OF PRESENTATION
	QuickLogic Corporation, referenced herein as QuickLogic or the Company, was founded in 1988 and reincorporated in Delaware in 1999. The Company develops and markets low power programmable solutions that enable customers to add differentiated features and capabilities to their mobile, consumer and industrial products. The Company is a fabless semiconductor company that designs, markets, and supports Customer Specific Standard Products, or CSSPs, Field Programmable Gate Arrays, or FPGAs, application solutions, associated design software and programming hardware.
	QuickLogic Corporation's fiscal year ends on the Sunday closest to December 31. Fiscal years 2013, 2012 and 2011 ended on December 29, 2013, December 30, 2012 and January 1, 2012, respectively.
	Liquidity
	The Company has financed its operations and capital investments through sales of common stock, capital and operating leases, and bank lines of credit. As of December 29, 2013, the Company's principal sources of liquidity consisted of its cash and cash equivalents of $37.4 million and $5.0 million in available credit under its revolving line of credit with Silicon Valley Bank which expires on June 27, 2014.
	The Company currently uses its cash to fund its capital expenditures and operating losses. Based on past performance and current expectations, the Company believes that its existing cash and cash equivalents, together with available financial resources from the revolving line of credit with Silicon Valley Bank will be sufficient to fund its operations and capital expenditures and provide adequate working capital for the next twelve months.
	Over the longer term, based on current expectations regarding revenue growth and margin improvement, the Company believes that its existing cash and cash equivalents, together with financial resources from its revolving line of credit with Silicon Valley Bank and its ability to sell additional shares to capital markets will be sufficient to satisfy its operations and capital expenditures.
	The Company's liquidity is affected by many factors including, among others: the level of revenue and gross profit as a result of the cyclicality of the semiconductor industry; the conversion of design opportunities into revenue; market acceptance of existing and new products including CSSPs based on its ArcticLink® and PolarPro® solution platforms; fluctuations in revenue as a result of product end-of-life; fluctuations in revenue as a result of the stage in the product life cycle of its customers' products; costs of securing access to and availability of adequate manufacturing capacity; levels of inventories; wafer purchase commitments; customer credit terms; the amount and timing of research and development expenditures; the timing of new product introductions; production volumes; product quality; sales and marketing efforts; the value and liquidity of its investment portfolio; changes in operating assets and liabilities; the ability to obtain or renew debt financing and to remain in compliance with the terms of existing credit facilities; the ability to raise funds from the sale of equity in the Company; the issuance and exercise of stock options and participation in the Company's employee stock purchase plan; and other factors related to the uncertainties of the industry and global economics. Accordingly, there can be no assurance that events in the future will not require the Company to seek additional capital or, if so required, that such capital will be available on terms acceptable to the Company.
	Principles of Consolidation
	The consolidated financial statements include the accounts of QuickLogic and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated.
	Foreign Currency
	The functional currency of the Company's non-U.S. operations is the U.S. dollar. Accordingly, all monetary assets and liabilities of these foreign operations are translated into U.S. dollars at current period-end exchange rates and non-monetary assets and related elements of expense are translated using historical exchange rates. Income and expense elements are translated to U.S. dollars using the average exchange rates in effect during the period. Gains and losses from the foreign currency transactions of these subsidiaries are recorded as interest income and other expense, net in the statements of operations.
	Use of Estimates
	The preparation of these consolidated financial statements in conformity with generally accepted accounting principles, or GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates, particularly in relation to revenue recognition, the allowance for doubtful accounts, sales returns, valuation of investments, valuation of long-lived assets, valuation of inventories including identification of excess quantities, market value and obsolescence, measurement of stock-based compensation awards, accounting for income taxes and estimating accrued liabilities.
	Concentration of Risk
	The Company's accounts receivable are denominated in U.S. dollars and are derived primarily from sales to customers located in North America, Asia Pacific, and Europe. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. See Note 13 for information regarding concentrations associated with accounts receivable.
	For the twelve months ended December 29, 2013, the Company generated 56% of its total revenue from shipments to a tier one customer, Samsung Electronics Co., Ltd. ("Samsung"). See Note 13 for information regarding concentrations associated with customers and distributors.

Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]	'
Significant Accounting Policies	'
	SIGNIFICANT ACCOUNTING POLICIES
	Cash Equivalents
	All highly liquid investments purchased with a remaining maturity of ninety days or less are considered cash equivalents. The Company's investment portfolio included in cash equivalents is generally comprised of investments that meet high credit quality standards. The Company's investment portfolio consists of money market funds, which are precluded from investing in auction rate securities. These funds invest in U.S. government obligations and repurchase agreements secured by U.S. Treasury obligations and U.S. government agency obligations. The fair value of this portfolio is based on market prices for securities with active secondary and resale markets.
	Fair Value
	The guidance for the fair value option for financial assets and financial liabilities provides companies the irrevocable option to measure many financial assets and liabilities at fair value with changes in fair value recognized in earnings or equity. The Company has not elected to measure any financial assets or liabilities at fair value that were not previously required to be measured at fair value.
	Foreign Currency Transactions
	All of the Company's sales and cost of manufacturing are transacted in U.S. dollars. The Company conducts a portion of its research and development activities in Canada and India and has sales and marketing activities in various countries outside of the United States. Most of these international expenses are incurred in local currency. Foreign currency transaction gains and losses, which are not significant, are included in interest income and other expense, net, as they occur. Operating expenses denominated in foreign currencies were approximately 19%, 19%, and 16% of total operating expenses in 2013, 2012, and 2011, respectively. The Company incurred a majority of these foreign currency expenses in Japan and Canada. The Company has not used derivative financial instruments to hedge its exposure to fluctuations in foreign currency and, therefore, is susceptible to fluctuations in foreign exchange gains or losses in its results of operations in future reporting periods.
	Inventories
	Inventories are stated at the lower of standard cost or net realizable value. Standard cost approximates actual cost on a first-in, first-out basis. The Company routinely evaluates quantities and values of its inventories in light of current market conditions and market trends and records reserves for quantities in excess of demand and product obsolescence. The evaluation, which inherently involves judgments as to assumptions about expected future demand and the impact of market conditions on these assumptions, takes into consideration historic usage, expected demand, anticipated sales price, the stage in the product life cycle of its customers' products, new product development schedules, the effect new products might have on the sale of existing products, product obsolescence, customer design activity, customer concentrations, product merchantability and other factors. Market conditions are subject to change. Actual consumption of inventories could differ from forecast demand, and this difference could have a material impact on the Company's gross margin and inventory balances based on additional provisions for excess or obsolete inventories or a benefit from inventories previously written down. The Company also regularly reviews the cost of inventories against estimated market value and records a lower of cost or market reserve for inventories that have a cost in excess of estimated market value, which could have a material impact on the Company's gross margin and inventory balances based on additional write-downs to net realizable value or a benefit from inventories previously written down.
	The Company's semiconductor products have historically had an unusually long product life cycle and obsolescence has not been a significant factor in the valuation of inventories. However, as the Company pursues opportunities in the mobile market and continues to develop new CSSPs and products, the Company believes its product life cycle will be shorter and increase the potential for obsolescence. A significant decrease in demand could result in an increase in the amount of excess inventory on hand. Although the Company makes every effort to ensure the accuracy of its forecasts of future product demand, any significant unanticipated changes in demand or frequent new product developments could have a significant impact on the value of its inventory and its results of operations.
	Property and Equipment
	Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets, generally one to seven years. Amortization of leasehold improvements and capital leases is computed on a straight-line basis over the shorter of the lease term or the estimated useful lives of the assets, generally one to seven years.
	Long-Lived Assets
	The Company reviews the recoverability of its long-lived assets, such as property and equipment, and investments, annually and when events or changes in circumstances occur that indicate that the carrying value of the asset or asset group may not be recoverable. The assessment of possible impairment is based on the Company's ability to recover the carrying value of the asset or asset group from the expected future pre-tax cash flows, undiscounted and without interest charges, of the related operations. If these cash flows are less than the carrying value of the asset or asset group, an impairment loss is recognized for the difference between the estimated fair value and the carrying value, and the carrying value of the related assets is reduced by this difference. The measurement of impairment requires management to estimate future cash flows and the fair value of long-lived assets. During 2013, 2012 and 2011, the Company wrote-off equipment with a net book value of $96,000, $25,000, and $102,000, respectively.
	Licensed Intellectual Property
	The Company licenses intellectual property that is incorporated into its products. Costs incurred under license agreements prior to the establishment of technological feasibility are included in research and development expense as incurred. Costs incurred for intellectual property once technological feasibility has been established and that can be used in multiple products are capitalized as a long-term asset. Once a product incorporating licensed intellectual property has production sales, the amount is amortized over the estimated useful life of the asset, generally up to five years.
	Revenue Recognition
	The Company supplies standard products which must be programmed before they can be used in an application. The Company's products may be programmed by us, distributors, end-customers or third parties.
	The Company recognizes revenue as products are shipped if evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, collection of the resulting receivable is reasonably assured and product returns are reasonably estimable. Revenue is recognized upon shipment of programmed and unprogrammed parts to both OEM customers and distributors, provided that legal title and risk of ownership have transferred. Parts held by distributors may be returned for quality reasons only under its standard warranty policy.
	Warranty Costs
	The Company warrants finished goods against defects in material and workmanship under normal use for twelve months from the date of shipment. The Company does not have significant product warranty related costs or liabilities.
	Advertising
	Costs related to advertising and promotion expenditures are charged to “Selling, general and administrative” expense as incurred. To date, costs related to advertising and promotion expenditures have not been material.
	Stock-Based Compensation
	The Company adopted the provisions to record stock-based compensation beginning fiscal year 2006. The Company accounts for stock-based compensation under the provisions of the amended authoritative guidance, and related interpretations which require the measurement and recognition of expense related to the fair value of stock-based compensation awards. The fair value of stock-based compensation awards is measured at the grant date and re-measured upon modification, as appropriate. The Company uses the Black-Scholes option pricing model to estimate the fair value of employee stock options and rights to purchase shares under the Company's 1999 Employee Stock Purchase Plan, or ESPP, consistent with the provisions of the amended authoritative guidance. The fair value of restricted stock awards, or RSAs, and restricted stock units, or RSUs, is based on the closing price of the Company's common stock on the date of grant. Equity compensation awards which vest with service are expensed on a straight-line basis over the requisite service period. Performance based awards that are expected to vest are expensed on a straight-line basis over the vesting period. The Company regularly reviews the assumptions used to compute the fair value of its stock-based awards and it will revise its assumptions as appropriate. In the event that assumptions used to compute the fair value of its stock-based awards are later determined to be inaccurate or if the Company changes its assumptions significantly in future periods, stock-based compensation expense and the results of operations could be materially impacted. See Note 11.
	Accounting for Income Taxes
	As part of the process of preparing the Company's financial statements, its required to estimate its income taxes in each of the jurisdictions in which the Company operates. This process involves estimating the Company's actual current tax exposure together with assessing temporary differences resulting from different tax and accounting treatment of items, such as deferred revenue, allowance for doubtful accounts, the impact of equity awards, depreciation and amortization and employee related accruals. These differences result in deferred tax assets and liabilities, which are included on the Company's balance sheets. The Company must then assess the likelihood that its deferred tax assets will be recovered from future taxable income and to the extent the Company believes that recovery is not more likely than not, it must establish a valuation allowance. To the extent the Company establishs a valuation allowance or increase this allowance in a period, it must include an expense within the tax provision in the statements of operations.
	Significant management judgment is required in determining the Company's provision for income taxes, the Company's deferred tax assets and liabilities and any valuation allowance recorded against the Company's net deferred tax assets. The Company's deferred tax assets, consisting primarily of net operating loss carryforwards, amounted to $63.6 million as of the end of 2013. The Company has also recorded a valuation allowance of $63.5 million as of the end of 2013 due to uncertainties related to the Company's ability to utilize its U.S. deferred tax assets before they expire. The valuation allowance is based on the uncertainty of the Company's estimates of taxable income and the period over which it expects to recover its deferred tax assets.
	The Company accounts for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that it anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes.
	Concentration of Credit and Suppliers
	Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash and cash equivalents and accounts receivable. Cash and cash equivalents are maintained with high quality institutions. The Company's accounts receivable are denominated in U.S. dollars and are derived primarily from sales to customers located in North America, Europe and Asia Pacific. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. See Note 13 for information regarding concentrations associated with accounts receivable.
	The Company depends on a limited number of contract manufacturers, subcontractors, and suppliers for wafer fabrication, assembly, programming and test of its devices, and for the supply of programming equipment, and these services are typically provided by one supplier for each of the Company's devices. The Company generally purchases these single or limited source services through standard purchase orders. Because the Company relies on independent subcontractors to perform these services, it cannot directly control its product delivery schedules, costs or quality levels. The Company's future success also depends on the financial viability of its independent subcontractors.
	Comprehensive Income (Loss)
	Comprehensive income (loss) includes all temporary changes in equity (net assets) during a period from non-owner sources. Comprehensive income (loss) includes unrealized holding gains or (losses) related to the TowerJazz ordinary shares. See Note 4.
	New Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board, or FASB, issued guidance on disclosure requirements for items reclassified out of Accumulated Other Comprehensive Income (“AOCI”). This new guidance requires entities to present (either on the face of the income statement or in the notes) the effects on the line items of the income statement for amounts reclassified out of AOCI. The new guidance became effective for the Company beginning December 15, 2012. The Company adopted this guidance prospectively in its interim period ended March 31, 2013 (see Note 12).
	In March 2013, the FASB issued guidance on a parent's accounting for the cumulative translation adjustment upon derecognition of a subsidiary or group of assets within a foreign entity. This new guidance requires that the parent release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The Company will adopt the new guidance in its interim period ending March 30, 2014. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.
	In July 2013, the FASB issued guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward exists. Under this guidance, an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward. This guidance is effective for the Company beginning after December 15, 2013. Other than the change in presentation within the Consolidated Balance Sheet, this new guidance will not have an impact on the consolidated financial statements.

Net Income (Loss) Per Share	'
	NET INCOME (LOSS) PER SHARE
	Basic net income (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share was computed using the weighted average number of common shares outstanding during the period plus potentially dilutive common shares outstanding during the period under the treasury stock method. In computing diluted net income (loss) per share, the weighted average stock price for the period is used in determining the number of shares assumed to be purchased from the exercise of stock options and warrants.
	For 2013, 2012, and 2011, 8.0 million shares, 7.6 million shares, and 8.0 million shares respectively, associated with equity awards outstanding and the estimated number of shares to be purchased under the current offering period of the 2009 Employee Stock Purchase Plan were not included in the calculation of diluted net income (loss) per share, as they were considered antidilutive due to the net loss the Company experienced during those years.

	FAIR VALUE MEASUREMENTS
	Pursuant to the accounting guidance for fair value measurements and its subsequent updates, fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market and it considers assumptions that market participants would use when pricing the asset or liability.
	The accounting guidance for fair value measurement also specifies a hierarchy of valuation techniques based upon whether the inputs to those valuation techniques reflect assumptions other market participants would use based upon market data obtained from independent sources (observable inputs) or reflect the company's own assumption of market participant valuation (unobservable inputs). The fair value hierarchy consists of the following three levels:
	•	Level 1 – Inputs are quoted prices in active markets for identical assets or liabilities.
	•	Level 2 – Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.
	•	Level 3 – Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.
	The following table presents the Company's financial assets that are measured at fair value on a recurring basis as of December 29, 2013 and December 30, 2012, consistent with the fair value hierarchy provisions of the authoritative guidance (in thousands):

	As of December 29, 2013, the Company had net operating loss carryforwards of approximately $113.0 million for federal and $54.4 million for state income tax purposes. If not utilized, these carryforwards will begin to expire beginning in 2014 for federal and state purposes. Included in the net operating loss carryforwards amount is $8.1 million for federal and $5.0 million for state income tax purposes, which, when recognized, will result in a credit to stockholders' equity.
	The Company has research credit carryforwards of approximately $2.8 million for federal and $3.8 million for state income tax purposes. If not utilized, the federal carryforwards will expire in various amounts beginning in 2018. The California credit can be carried forward indefinitely.
	Under the Tax Reform Act of 1986, the amount of and the benefit from net operating loss carryforwards and credit carryforwards may be impaired or limited in certain circumstances. Events which may restrict utilization of a company's net operating loss and credit carryforwards include, but are not limited to, certain ownership change limitations as defined in Internal Revenue Code Section 382 and similar state provisions. In the event the Company has had a change of ownership, utilization of carryforwards could be restricted to an annual limitation. The annual limitation may result in the expiration of net operating loss carryforwards and credit carryforwards before utilization.
	U.S. income taxes and foreign withholding taxes associated with the repatriation of earnings of foreign subsidiaries were not provided for on a cumulative total of $1.0 million of undistributed earnings for certain foreign subsidiaries as of the end of fiscal 2013. The Company intends to reinvest these earnings indefinitely in the Company's foreign subsidiaries. If these earnings were distributed to the United States in the form of dividends or otherwise, or if the shares of the relevant foreign subsidiaries were sold or otherwise transferred, the Company would be subject to additional U.S. income taxes (subject to an adjustment for foreign tax credits) and foreign withholding taxes. Determination of the amount of unrecognized deferred income tax liability related to these earnings is not practicable.
	A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):
		December 29, 2013			December 30, 2012			January 1, 2012

	Ending balance of unrecognized tax benefits	$	79		$	79		$	77
	The amount of unrecognized tax benefits that would affect our effective tax rate if recognized is $79,000 as of December 29, 2013. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. As of December 29, 2013 and December 30, 2012 the Company had approximately $40,000 and $33,000 of accrued interest and penalties related to uncertain tax positions.
	The Company is subject to U.S. federal income tax as well as income taxes in many U.S. states and foreign jurisdictions in which the Company operates. As of December 29, 2013, fiscal years 2009 onward remain open to examination by the U.S. taxing authorities and fiscal years 2005 onward remain open to examination in Canada. The U.S. federal and U.S. state taxing authorities may choose to audit tax returns for tax years beyond the statute of limitation period due to significant tax attribute carryforwards from prior years, making adjustments only to carryforward attributes. The Company estimates that its unrecognized tax benefits will not change significantly within the next twelve months.

	Issuance of Common Stock
	On July 31, 2013, the Company filed a shelf registration statement on Form S-3 under which the Company may, from time to time, sell securities in one or more offerings up to a total dollar amount of $40.0 million. The Company's shelf registration statement was declared effective on August 30, 2013 and expires in August 2016.
	In November 2013, the Company issued an aggregate of 8,740,000 shares of common stock, $0.001 par value, in an underwritten public offering at a price of $2.90 per share. The Company received net proceeds from the offering of $23.1 million, net of underwriter's commission and other offering expenses of 2.2 million.
	On June 1, 2012, the Company filed a registration statement on Form S-3 MEF to increase the amount of securities that may be sold under the shelf registration statement by $3.4 million.
	In June 2012, the Company issued an aggregate of 5,122,000 shares of common stock and warrants to purchase up to an aggregate of 2,304,900 shares of common stock in a confidentially marketed underwritten offering. The common stock and warrants were issued in units (the “Units”), with each Unit consisting of (i) one share of common stock and (ii) a warrant to purchase 0.45 of a share of common stock, at a price of $2.50 per Unit. The Company received total net proceeds from the offering of $11.9 million, net of underwriting discounts and other offering expenses of $929,000.
	The warrants are exercisable any time for a period of 60 months from the date of issuance on June 6, 2012, and are exercisable at a price of $2.98 per share. The Company allocated the proceeds between the common stock and the warrants based on the relative fair value of each on the date of issuance. The estimated grant date fair value was $0.97 per warrant and was calculated based on the following assumptions used in the Black-Scholes model: expected term of 5 years, risk-free interest rate of 0.89%, expected volatility of 62.18% and expected dividend of zero.

	1999 Stock Plan
	The 1999 Stock Plan, or 1999 Plan, provided for the issuance of incentive and nonqualified options, restricted stock units and restricted stock. Equity awards granted under the 1999 Plan have a term of up to ten years. Options typically vest at a rate of 25% one year after the vesting commencement date, and one forty-eighth for each month of service thereafter. In March 2009, the Board adopted the 2009 Stock Plan which was approved by the Company's stockholders on April 22, 2009. Effective April 22, 2009, no further stock options may be granted under the 1999 Plan.
	2009 Stock Plan
	The 2009 Stock Plan, or 2009 Plan, was amended and restated by the Board of Directors in March 2011 and approved by the Company's stockholders on April 28, 2011 to, among other things, reserve an additional 1.5 million shares of common stock for issuance under the Plan. As of December 29, 2013, approximately 7.0 million shares were reserved for issuance under the 2009 Plan. Equity awards that are cancelled, forfeited or repurchased under the 1999 Plan become available for grant under the 2009 Plan, up to a maximum of an additional 7.5 million shares. Equity awards granted under the 2009 Plan have a term of up to ten years. Options typically vest at a rate of 25% one year after the vesting commencement date, and one forty-eighth for each month of service thereafter. The Company may implement different vesting schedules in the future with respect to any new equity awards.
	Employee Stock Purchase Plan
	The 2009 Employee Stock Purchase Plan, or 2009 ESPP, was adopted in March 2009. The Company has reserved 2.3 million shares for issuance under the 2009 ESPP. The 2009 ESPP provides for six month offering periods. Participants purchase shares through payroll deductions of up to 20% of an employee's total compensation (maximum of 20,000 shares per offering period). The 2009 ESPP permits the Board of Directors to determine, prior to each offering period, whether participants purchase shares at: (i) 85% of the fair market value of the common stock at the end of the offering period; or (ii) 85% of the lower of the fair market value of the common stock at the beginning or the end of an offering period. The Board of Directors has determined that, until further notice, future offering periods will be made at 85% of the lower of the fair market value of the common stock at the beginning or the end of an offering period.

Stock-Based Compensation	'
	STOCK-BASED COMPENSATION
	The Company's equity incentive program is a broad-based, long-term retention program intended to attract, motivate, and retain talented employees as well as align stockholder and employee interests. The Company provides stock-based incentive compensation, or awards, to eligible employees and non-employee directors. Awards that may be granted under the program include non-qualified and incentive stock options, restricted stock units, or RSUs, performance-based restricted stock units, or PRSUs, and stock bonus units. To date, awards granted under the program consist of stock options, RSUs and PRSUs. The majority of stock-based awards granted under the program vest over four years. Stock options granted under the program have a maximum contractual term of ten years.
	Stock-based compensation expense is recognized in the Company's consolidated statements of operations and includes compensation expense for the stock-based compensation awards granted or modified subsequent to January 1, 2006, based on the grant date fair value estimated in accordance with the provisions of the amended authoritative guidance. The impact on the Company's results of operations of recording stock-based compensation expense for fiscal years 2013, 2012 and 2011 was as follows (in thousands):
		Fiscal Years
		2013			2012				2011

	Research and development	666			455				458
	Selling, general and administrative	1,081			1,369				1,087
	Total costs and expenses	$	1,979		$	2,003			$	1,676
	In 2013, the Company granted restricted stock units, or RSUs, to employees with vesting terms from fully vested to 12 months vesting. Total stock-based compensation related to RSUs was $590,000 in 2013. The Company issued net shares for the vested RSUs, withholding shares in settlement of employee tax withholding obligations. In 2013, the Company also granted performance-based restricted stock units, or PRSUs, to new employees and the stock-based compensation related to PRSUs was $64,000.
	The amount of stock-based compensation included in inventories at the end of 2013, 2012 and 2011 was not significant.
	Valuation Assumptions
	The Company uses the Black-Scholes option pricing model to estimate the fair value of employee stock options and rights to purchase shares under the Company's 2009 ESPP. Using the Black-Scholes pricing model requires the Company to develop highly subjective assumptions including the expected term of awards, expected volatility of its stock, expected risk-free interest rate and expected dividend rate over the term of the award. The Company's expected term of awards assumption is based primarily on its historical experience with similar grants. The Company's expected stock price volatility assumption for both stock options and ESPP shares is based on the historical volatility of the Company's stock, using the daily average of the opening and closing prices and measured using historical data appropriate for the expected term. The risk-free interest rate assumption approximates the risk-free interest rate of a Treasury Constant Maturity bond with a maturity approximately equal to the expected term of the stock option or ESPP shares. This fair value is expensed over the requisite service period of the award. The fair value of RSUs and PRSUs is based on the closing price of the Company's common stock on the date of grant. Equity compensation awards which vest with service are expensed using the straight-line attribution method over the requisite service period.
	In addition to the assumptions used in the Black-Scholes pricing model, the amended authoritative guidance requires that the Company recognize expense for awards ultimately expected to vest; therefore the Company is required to develop an estimate of the number of awards expected to be forfeited prior to vesting, or forfeiture rate. The forfeiture rate is estimated based on historical pre-vest cancellation experience and is applied to all share-based awards.
	The following weighted average assumptions are included in the estimated fair value calculations for stock option grants:
		Fiscal Years
		2013		2012			2011
	Expected term (years)	6.1		6.3			5.7
	Risk-free interest rate	1.74	%	0.98	%		1.16	%
	Expected volatility	59	%	61	%		61	%
	Expected dividend	—		—			—
	The methodologies for determining the above values were as follows:
	•	Expected term: The expected term represents the period that the Company's stock-based awards are expected to be outstanding and is estimated based on historical experience.
	•	Risk-free interest rate: The risk-free interest rate assumption is based upon the risk-free rate of a Treasury Constant Maturity bond with a maturity appropriate for the expected term of the Company's employee stock options.
	•	Expected volatility: The Company determines expected volatility based on historical volatility of the Company's common stock according to the expected term of the options.
	•	Expected dividend: The expected dividend assumption is based on the Company's intent not to issue a dividend under its dividend policy.
	The weighted average estimated fair value for options granted during 2013, 2012 and 2011 was $1.82, $1.36, and $1.53 per option, respectively. As of the end of 2013, the fair value of unvested stock options, net of expected forfeitures, was approximately $2.7 million. This unrecognized stock-based compensation expense is expected to be recorded over a weighted average period of 2.61 years.

	The aggregate intrinsic value in the table above represents the total pretax intrinsic value, based on the Company's closing stock price of $3.86 as of the end of the Company's current reporting period, which would have been received by the option holders had all option holders exercised their options as of that date.
	The total intrinsic value of options exercised during 2013, 2012 and 2011 was $139,000, $343,000 and $1.8 million, respectively. Total cash received from employees as a result of employee stock option exercises during 2013, 2012 and 2011 was approximately $365,000, $711,000 and $1.6 million, respectively. The Company settles employee stock option exercises with newly issued common shares. In connection with these exercises, there was no tax benefit realized by the Company due to the Company's current loss position. Total stock-based compensation related to stock options was $1.1 million, $1.4 million, and $1.5 million for 2013, 2012, and 2011, respectively.

Restricted Stock Units
RSUs entitle the holder to receive, at no cost, one common share for each restricted stock unit on the vesting date as it vests. The Company withholds shares in settlement of employee tax withholding obligations upon the vesting of restricted stock units. The stock-based compensation related to grants of vested RSUs was $590,000 in 2013. In 2013, the Company also granted PRSUs, to new employees and the stock-based compensation related to PRSUs was $64,000.

Employee Stock Purchase Plan
The weighted average estimated fair value, as defined by the amended authoritative guidance, of rights issued pursuant to the Company's ESPP during 2013, 2012 and 2011 was $0.71, $0.74 and $0.84, respectively. Sales under the ESPP were 357,000 shares of common stock at an average price of $1.74 for 2013, 270,000 shares of common stock at an average price of $1.95 for 2012, and 171,000 shares of common stock at an average price of $2.47 for 2011.
Under the 2009 ESPP, the Company issued 357,000 shares at a price of $1.74 per share during 2013. As of December 29, 2013, 1.2 million shares under the 2009 ESPP remained available for issuance. For 2013, the Company recorded compensation expense related to the ESPP of $203,000.
The fair value of rights issued pursuant to the Company's ESPP was estimated on the commencement date of each offering period using the following weighted average assumptions:
	Fiscal Years
	2013		2012			2011
Expected life (months)	6.1		6			6.1
Risk-free interest rate	0.09	%	0.14	%		0.08	%
Volatility	39	%	56	%		56	%
Dividend yield	—		—			—
The methodologies for determining the above values were as follows:
•	Expected term: The expected term represents the length of the purchase period contained in the ESPP.
•	Risk-free interest rate: The risk-free interest rate assumption is based upon the risk-free rate of a Treasury Constant Maturity bond with a maturity appropriate for the term of the purchase period.
•	Volatility: The Company determines expected volatility based on historical volatility of the Company's common stock for the term of the purchase period.
•	Dividend Yield: The expected dividend assumption is based on the Company's intent not to issue a
dividend under its dividend policy.
As of the end of 2013, the unrecognized stock-based compensation expense relating to the Company's ESPP is $89,000 and was expected to be recognized over a weighted average period of approximately 4.5 months.

Shelf Registration Statement	'
	SHELF REGISTRATION STATEMENT
	On July 31, 2013, the Company filed a shelf registration statement on Form S-3 under which the Company may, from time to time, sell securities in one or more offerings up to a total dollar amount of $40.0 million. The Company's shelf registration statement was declared effective on August 30, 2013 and expires in August 2016.
	In November 2013, the Company issued an aggregate of 8,740,000 shares of common stock, $0.001 par value, in an underwritten public offering at a price of $2.90 per share. The Company received net proceeds from the offering of $23.1 million, net of underwriter's commission and other offering expenses of $2.2 million.
	On June 1, 2012, the Company filed a registration statement on Form S-3 MEF to increase the amount of securities that may be sold under the shelf registration statement by $3.4 million.
	In June 2012, the Company issued an aggregate of 5,122,000 shares of common stock and warrants to purchase up to an aggregate of 2,304,900 shares of common stock in a confidentially marketed underwritten offering. The common stock and warrants were issued in units (the “Units”), with each Unit consisting of (i) one share of common stock and (ii) a warrant to purchase 0.45 of a share of common stock, at a price of $2.50 per Unit. The Company received total net proceeds from the offering of $11.9 million, net of underwriting discounts and other offering expenses of $929,000.
	The warrants are exercisable any time for a period of 60 months from the date of issuance on June 6, 2012 and are exercisable at a price of $2.98 per share. The Company allocated the proceeds between the common stock and the warrants based on the relative fair value of each on the date of issuance. The estimated grant date fair value was $0.97 per warrant and was calculated based on the following assumptions used in the Black-Scholes model: expected term of 5 years, risk-free interest rate of 0.89%, expected volatility of 62.18% and expected dividend of zero.

Liquidity	'
	Liquidity
	The Company has financed its operations and capital investments through sales of common stock, capital and operating leases, and bank lines of credit. As of December 29, 2013, the Company's principal sources of liquidity consisted of its cash and cash equivalents of $37.4 million and $5.0 million in available credit under its revolving line of credit with Silicon Valley Bank which expires on June 27, 2014.
	The Company currently uses its cash to fund its capital expenditures and operating losses. Based on past performance and current expectations, the Company believes that its existing cash and cash equivalents, together with available financial resources from the revolving line of credit with Silicon Valley Bank will be sufficient to fund its operations and capital expenditures and provide adequate working capital for the next twelve months.
	Over the longer term, based on current expectations regarding revenue growth and margin improvement, the Company believes that its existing cash and cash equivalents, together with financial resources from its revolving line of credit with Silicon Valley Bank and its ability to sell additional shares to capital markets will be sufficient to satisfy its operations and capital expenditures.
	The Company's liquidity is affected by many factors including, among others: the level of revenue and gross profit as a result of the cyclicality of the semiconductor industry; the conversion of design opportunities into revenue; market acceptance of existing and new products including CSSPs based on its ArcticLink® and PolarPro® solution platforms; fluctuations in revenue as a result of product end-of-life; fluctuations in revenue as a result of the stage in the product life cycle of its customers' products; costs of securing access to and availability of adequate manufacturing capacity; levels of inventories; wafer purchase commitments; customer credit terms; the amount and timing of research and development expenditures; the timing of new product introductions; production volumes; product quality; sales and marketing efforts; the value and liquidity of its investment portfolio; changes in operating assets and liabilities; the ability to obtain or renew debt financing and to remain in compliance with the terms of existing credit facilities; the ability to raise funds from the sale of equity in the Company; the issuance and exercise of stock options and participation in the Company's employee stock purchase plan; and other factors related to the uncertainties of the industry and global economics. Accordingly, there can be no assurance that events in the future will not require the Company to seek additional capital or, if so required, that such capital will be available on terms acceptable to the Company.
Principles of Consolidation	'
	Principles of Consolidation
	The consolidated financial statements include the accounts of QuickLogic and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated.
Use of Estimates	'
	Use of Estimates
	The preparation of these consolidated financial statements in conformity with generally accepted accounting principles, or GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates, particularly in relation to revenue recognition, the allowance for doubtful accounts, sales returns, valuation of investments, valuation of long-lived assets, valuation of inventories including identification of excess quantities, market value and obsolescence, measurement of stock-based compensation awards, accounting for income taxes and estimating accrued liabilities.
Cash Equivalents	'
	Cash Equivalents
	All highly liquid investments purchased with a remaining maturity of ninety days or less are considered cash equivalents. The Company's investment portfolio included in cash equivalents is generally comprised of investments that meet high credit quality standards. The Company's investment portfolio consists of money market funds, which are precluded from investing in auction rate securities. These funds invest in U.S. government obligations and repurchase agreements secured by U.S. Treasury obligations and U.S. government agency obligations. The fair value of this portfolio is based on market prices for securities with active secondary and resale markets.
Fair Value	'
	Fair Value
	The guidance for the fair value option for financial assets and financial liabilities provides companies the irrevocable option to measure many financial assets and liabilities at fair value with changes in fair value recognized in earnings or equity. The Company has not elected to measure any financial assets or liabilities at fair value that were not previously required to be measured at fair value.
Foreign Currency Transactions	'
	Foreign Currency
	The functional currency of the Company's non-U.S. operations is the U.S. dollar. Accordingly, all monetary assets and liabilities of these foreign operations are translated into U.S. dollars at current period-end exchange rates and non-monetary assets and related elements of expense are translated using historical exchange rates. Income and expense elements are translated to U.S. dollars using the average exchange rates in effect during the period. Gains and losses from the foreign currency transactions of these subsidiaries are recorded as interest income and other expense, net in the statements of operations.
	Foreign Currency Transactions
	All of the Company's sales and cost of manufacturing are transacted in U.S. dollars. The Company conducts a portion of its research and development activities in Canada and India and has sales and marketing activities in various countries outside of the United States. Most of these international expenses are incurred in local currency. Foreign currency transaction gains and losses, which are not significant, are included in interest income and other expense, net, as they occur. Operating expenses denominated in foreign currencies were approximately 19%, 19%, and 16% of total operating expenses in 2013, 2012, and 2011, respectively. The Company incurred a majority of these foreign currency expenses in Japan and Canada. The Company has not used derivative financial instruments to hedge its exposure to fluctuations in foreign currency and, therefore, is susceptible to fluctuations in foreign exchange gains or losses in its results of operations in future reporting periods.
Inventories	'
	Inventories
	Inventories are stated at the lower of standard cost or net realizable value. Standard cost approximates actual cost on a first-in, first-out basis. The Company routinely evaluates quantities and values of its inventories in light of current market conditions and market trends and records reserves for quantities in excess of demand and product obsolescence. The evaluation, which inherently involves judgments as to assumptions about expected future demand and the impact of market conditions on these assumptions, takes into consideration historic usage, expected demand, anticipated sales price, the stage in the product life cycle of its customers' products, new product development schedules, the effect new products might have on the sale of existing products, product obsolescence, customer design activity, customer concentrations, product merchantability and other factors. Market conditions are subject to change. Actual consumption of inventories could differ from forecast demand, and this difference could have a material impact on the Company's gross margin and inventory balances based on additional provisions for excess or obsolete inventories or a benefit from inventories previously written down. The Company also regularly reviews the cost of inventories against estimated market value and records a lower of cost or market reserve for inventories that have a cost in excess of estimated market value, which could have a material impact on the Company's gross margin and inventory balances based on additional write-downs to net realizable value or a benefit from inventories previously written down.
	The Company's semiconductor products have historically had an unusually long product life cycle and obsolescence has not been a significant factor in the valuation of inventories. However, as the Company pursues opportunities in the mobile market and continues to develop new CSSPs and products, the Company believes its product life cycle will be shorter and increase the potential for obsolescence. A significant decrease in demand could result in an increase in the amount of excess inventory on hand. Although the Company makes every effort to ensure the accuracy of its forecasts of future product demand, any significant unanticipated changes in demand or frequent new product developments could have a significant impact on the value of its inventory and its results of operations.
Property Plant and Equipment and Long-Lived Assets	'
	Property and Equipment
	Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets, generally one to seven years. Amortization of leasehold improvements and capital leases is computed on a straight-line basis over the shorter of the lease term or the estimated useful lives of the assets, generally one to seven years.
	Long-Lived Assets
	The Company reviews the recoverability of its long-lived assets, such as property and equipment, and investments, annually and when events or changes in circumstances occur that indicate that the carrying value of the asset or asset group may not be recoverable. The assessment of possible impairment is based on the Company's ability to recover the carrying value of the asset or asset group from the expected future pre-tax cash flows, undiscounted and without interest charges, of the related operations. If these cash flows are less than the carrying value of the asset or asset group, an impairment loss is recognized for the difference between the estimated fair value and the carrying value, and the carrying value of the related assets is reduced by this difference. The measurement of impairment requires management to estimate future cash flows and the fair value of long-lived assets. During 2013, 2012 and 2011, the Company wrote-off equipment with a net book value of $96,000, $25,000, and $102,000, respectively.
Licensed Intellectual Property	'
	Licensed Intellectual Property
	The Company licenses intellectual property that is incorporated into its products. Costs incurred under license agreements prior to the establishment of technological feasibility are included in research and development expense as incurred. Costs incurred for intellectual property once technological feasibility has been established and that can be used in multiple products are capitalized as a long-term asset. Once a product incorporating licensed intellectual property has production sales, the amount is amortized over the estimated useful life of the asset, generally up to five years.
Revenue Recognition	'
	Revenue Recognition
	The Company supplies standard products which must be programmed before they can be used in an application. The Company's products may be programmed by us, distributors, end-customers or third parties.
	The Company recognizes revenue as products are shipped if evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, collection of the resulting receivable is reasonably assured and product returns are reasonably estimable. Revenue is recognized upon shipment of programmed and unprogrammed parts to both OEM customers and distributors, provided that legal title and risk of ownership have transferred. Parts held by distributors may be returned for quality reasons only under its standard warranty policy.
Warranty Costs	'
	Warranty Costs
	The Company warrants finished goods against defects in material and workmanship under normal use for twelve months from the date of shipment. The Company does not have significant product warranty related costs or liabilities.
Advertising	'
	Advertising
	Costs related to advertising and promotion expenditures are charged to “Selling, general and administrative” expense as incurred. To date, costs related to advertising and promotion expenditures have not been material.
Stock-Based Compensation	'
	Stock-Based Compensation
	The Company adopted the provisions to record stock-based compensation beginning fiscal year 2006. The Company accounts for stock-based compensation under the provisions of the amended authoritative guidance, and related interpretations which require the measurement and recognition of expense related to the fair value of stock-based compensation awards. The fair value of stock-based compensation awards is measured at the grant date and re-measured upon modification, as appropriate. The Company uses the Black-Scholes option pricing model to estimate the fair value of employee stock options and rights to purchase shares under the Company's 1999 Employee Stock Purchase Plan, or ESPP, consistent with the provisions of the amended authoritative guidance. The fair value of restricted stock awards, or RSAs, and restricted stock units, or RSUs, is based on the closing price of the Company's common stock on the date of grant. Equity compensation awards which vest with service are expensed on a straight-line basis over the requisite service period. Performance based awards that are expected to vest are expensed on a straight-line basis over the vesting period. The Company regularly reviews the assumptions used to compute the fair value of its stock-based awards and it will revise its assumptions as appropriate. In the event that assumptions used to compute the fair value of its stock-based awards are later determined to be inaccurate or if the Company changes its assumptions significantly in future periods, stock-based compensation expense and the results of operations could be materially impacted. See Note 11.
	Valuation Assumptions
	The Company uses the Black-Scholes option pricing model to estimate the fair value of employee stock options and rights to purchase shares under the Company's 2009 ESPP. Using the Black-Scholes pricing model requires the Company to develop highly subjective assumptions including the expected term of awards, expected volatility of its stock, expected risk-free interest rate and expected dividend rate over the term of the award. The Company's expected term of awards assumption is based primarily on its historical experience with similar grants. The Company's expected stock price volatility assumption for both stock options and ESPP shares is based on the historical volatility of the Company's stock, using the daily average of the opening and closing prices and measured using historical data appropriate for the expected term. The risk-free interest rate assumption approximates the risk-free interest rate of a Treasury Constant Maturity bond with a maturity approximately equal to the expected term of the stock option or ESPP shares. This fair value is expensed over the requisite service period of the award. The fair value of RSUs and PRSUs is based on the closing price of the Company's common stock on the date of grant. Equity compensation awards which vest with service are expensed using the straight-line attribution method over the requisite service period.
Accounting for Income Taxes	'
	Accounting for Income Taxes
	As part of the process of preparing the Company's financial statements, its required to estimate its income taxes in each of the jurisdictions in which the Company operates. This process involves estimating the Company's actual current tax exposure together with assessing temporary differences resulting from different tax and accounting treatment of items, such as deferred revenue, allowance for doubtful accounts, the impact of equity awards, depreciation and amortization and employee related accruals. These differences result in deferred tax assets and liabilities, which are included on the Company's balance sheets. The Company must then assess the likelihood that its deferred tax assets will be recovered from future taxable income and to the extent the Company believes that recovery is not more likely than not, it must establish a valuation allowance. To the extent the Company establishs a valuation allowance or increase this allowance in a period, it must include an expense within the tax provision in the statements of operations.
	Significant management judgment is required in determining the Company's provision for income taxes, the Company's deferred tax assets and liabilities and any valuation allowance recorded against the Company's net deferred tax assets. The Company's deferred tax assets, consisting primarily of net operating loss carryforwards, amounted to $63.6 million as of the end of 2013. The Company has also recorded a valuation allowance of $63.5 million as of the end of 2013 due to uncertainties related to the Company's ability to utilize its U.S. deferred tax assets before they expire. The valuation allowance is based on the uncertainty of the Company's estimates of taxable income and the period over which it expects to recover its deferred tax assets.
	The Company accounts for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that it anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes.
Concentration Risk	'
	Concentration of Risk
	The Company's accounts receivable are denominated in U.S. dollars and are derived primarily from sales to customers located in North America, Asia Pacific, and Europe. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. See Note 13 for information regarding concentrations associated with accounts receivable.
	Concentration of Credit and Suppliers
	Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash and cash equivalents and accounts receivable. Cash and cash equivalents are maintained with high quality institutions. The Company's accounts receivable are denominated in U.S. dollars and are derived primarily from sales to customers located in North America, Europe and Asia Pacific. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. See Note 13 for information regarding concentrations associated with accounts receivable.
	The Company depends on a limited number of contract manufacturers, subcontractors, and suppliers for wafer fabrication, assembly, programming and test of its devices, and for the supply of programming equipment, and these services are typically provided by one supplier for each of the Company's devices. The Company generally purchases these single or limited source services through standard purchase orders. Because the Company relies on independent subcontractors to perform these services, it cannot directly control its product delivery schedules, costs or quality levels. The Company's future success also depends on the financial viability of its independent subcontractors.
Comprehensive Income (Loss)	'
	Comprehensive Income (Loss)
	Comprehensive income (loss) includes all temporary changes in equity (net assets) during a period from non-owner sources. Comprehensive income (loss) includes unrealized holding gains or (losses) related to the TowerJazz ordinary shares. See Note 4.
New Accounting Pronouncements	'
	New Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board, or FASB, issued guidance on disclosure requirements for items reclassified out of Accumulated Other Comprehensive Income (“AOCI”). This new guidance requires entities to present (either on the face of the income statement or in the notes) the effects on the line items of the income statement for amounts reclassified out of AOCI. The new guidance became effective for the Company beginning December 15, 2012. The Company adopted this guidance prospectively in its interim period ended March 31, 2013 (see Note 12).
	In March 2013, the FASB issued guidance on a parent's accounting for the cumulative translation adjustment upon derecognition of a subsidiary or group of assets within a foreign entity. This new guidance requires that the parent release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The Company will adopt the new guidance in its interim period ending March 30, 2014. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.
	In July 2013, the FASB issued guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward exists. Under this guidance, an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward. This guidance is effective for the Company beginning after December 15, 2013. Other than the change in presentation within the Consolidated Balance Sheet, this new guidance will not have an impact on the consolidated financial statements.
Earnings Per Share	'
	Basic net income (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share was computed using the weighted average number of common shares outstanding during the period plus potentially dilutive common shares outstanding during the period under the treasury stock method. In computing diluted net income (loss) per share, the weighted average stock price for the period is used in determining the number of shares assumed to be purchased from the exercise of stock options and warrants
