Accounting Policies [Abstract]	'
NOTE 1—THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	Basis of presentation
	The accompanying unaudited condensed consolidated financial statements of GSI Technology, Inc. and its subsidiaries (“GSI” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission.  Accordingly, the interim financial statements do not include all of the information and footnotes required by generally accepted accounting principles for annual financial statements.  These interim financial statements contain all adjustments (which consist of only normal, recurring adjustments) that are, in the opinion of management, necessary to state fairly the interim financial information included therein.  The Company believes that the disclosures are adequate to make the information not misleading.  However, these financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2013.
	The consolidated results of operations for the three months ended September 30, 2013 are not necessarily indicative of the results to be expected for the entire fiscal year.
	Significant accounting policies
	The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2013.
	Litigation and settlement costs
	From time to time, the Company is involved in legal actions. The Company currently is a party to pending legal proceedings which it is defending aggressively.  See Note 6 for additional information regarding this pending litigation.  There are many uncertainties associated with any litigation, and the Company may not prevail.  The litigation, regardless of its eventual outcome, will be costly and time consuming and, should the outcome be adverse to the Company, could result in the Company being required to pay significant monetary damages.  If that occurs, our business, financial condition and results of operations could be materially and adversely affected. If information becomes available that causes us to determine that a loss in any of our pending litigation, or the settlement of such litigation, is probable, and we can reasonably estimate the loss associated with such events, we will record the loss in accordance with GAAP. However, the actual liability in any such litigation may be materially different from our estimates, which could require us to record additional costs.

Income Tax Disclosure [Abstract]	'
NOTE 4—INCOME TAXES	'
	The current portion of the Company’s unrecognized tax benefits was $0 at September 30, 2013 and March 31, 2013  The long-term portion at September 30, 2013 and March 31, 2013 was $2,754,000 and $2,803,000, respectively, of which the timing of the resolution is uncertain.  As of September 30, 2013, $323,000 of unrecognized tax benefits had been recorded as a reduction to net deferred tax assets.  The unrecognized tax benefit balance of $2,895,000 as of September 30, 2013 would affect the Company’s effective tax rate if recognized.  It is possible, however, that some months or years may elapse before an uncertain position for which the Company has established a reserve is resolved.
	Management believes that it is reasonably possible that within the next twelve months the Company could have a reduction in uncertain tax benefits of up to $637,000, including interest and penalties, related to positions taken with respect to credits and loss carryforwards on previously filed tax returns.
	The Company’s policy is to include interest and penalties related to unrecognized tax benefits within the provision for income taxes in the Condensed Consolidated Statements of Operations.
	The Company is subject to taxation in the United States and various state and foreign jurisdictions.  Fiscal years 2010 through 2013 remain open to examination by federal tax authorities, and fiscal years 2009 through 2013 remain open to examination by California tax authorities.  In the three months ended June 30, 2012, the Company settled an examination by the California Franchise Tax Board.  The tax provision for the six month period ended September 30, 2012 includes a discrete benefit of $168,000 associated with the net result of the settlement and the associated tax reserves, including interest to date.
	The Company’s estimated annual effective income tax rate was approximately (3.6%) and 29.3% as of September 30, 2013 and 2012, respectively.  The differences between the effective income tax rate and the applicable statutory U.S. income tax rate in each period were primarily due to the effects of tax credits, foreign tax rate differentials and tax free interest income, offset by stock-based compensation expense.

	Fair value measurements
	Authoritative accounting guidance for fair value measurements provides a framework for measuring fair value and related disclosure.  The guidance applies to all financial assets and financial liabilities that are measured on a recurring basis.  The guidance requires fair value measurement to be classified and disclosed in one of the following three categories:
	Level 1: Valuations based on quoted prices in active markets for identical assets and liabilities.  The fair value of available-for-sale securities included in the Level 1 category is based on quoted prices that are readily and regularly available in an active market.  As of September 30, 2013, the Level 1 category included money market funds of $10.5 million, which were included in cash and cash equivalents in the Condensed Consolidated Balance Sheet.
	Level 2: Valuations based on observable inputs (other than Level 1 prices), such as quoted prices for similar assets at the measurement date; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly. The fair value of available-for-sale securities included in the Level 2 category is based on the market values obtained from an independent pricing service that were evaluated using pricing models that vary by asset class and may incorporate available trade, bid and other market information and price quotes from well established independent pricing vendors and broker-dealers. As of September 30, 2013, the Level 2 category included short-term investments of $26.1 million and long-term investments of $34.6 million, which were comprised of certificates of deposit, corporate debt securities and government and agency securities.
	Level 3: Valuations based on inputs that are unobservable and involve management judgment and the reporting entity’s own assumptions about market participants and pricing.  As of September 30, 2013, the Company had no Level 3 financial assets measured at fair value in the Condensed Consolidated Balance Sheet.
	The fair value of financial assets and liabilities measured on a recurring basis is as follows (in thousands):
				Fair Value Measurements at Reporting Date Using

	Short-term and long-term investments
	All of the Company’s short-term and long-term investments are classified as available-for-sale.  Available-for-sale debt securities with maturities greater than twelve months are classified as long-term investments when they are not intended for use in current operations.  Investments in available-for-sale securities are reported at fair value with unrecognized gains (losses), net of tax, as a component of accumulated other comprehensive income in the Condensed Consolidated Balance Sheets.  The Company had money market funds of $10.5 million and $10.4 million at September 30, 2013 and March 31, 2013, respectively, included in cash and cash equivalents in the Condensed Consolidated Balance Sheet.  The Company monitors its investments for impairment periodically and records appropriate reductions in carrying values when declines are determined to be other-than-temporary.

The Company’s investment portfolio consists of both corporate and governmental securities that have a maximum maturity of three years. All unrealized gains are due to changes in interest rates and bond yields.  Subject to normal credit risks, the Company has the ability to realize the full value of all these investments upon maturity.
As of September 30, 2013, the deferred tax asset related to unrecognized gains and losses on short-term and long-term investments was $3,000. As of March 31, 2013, the deferred tax liability related to unrecognized gains and losses on short-term and long-term investments was $14,000.
As of September 30, 2013, contractual maturities of the Company’s available-for-sale non-equity investments were as follows:

NOTE 6—COMMITMENTS AND CONTINGENCIES	'
	Indemnification obligations
	The Company is a party to a variety of agreements pursuant to which it may be obligated to indemnify the other party with respect to certain matters. Typically, these obligations arise in the context of contracts entered into by the Company, under which the Company agrees to hold the other party harmless against losses arising from a breach of representations and covenants related to such matters as title to assets sold and certain intellectual property rights. In each of these circumstances, the Company's indemnification obligations are conditioned on the other party making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge the other party’s claims. Further, the Company’s obligations under these agreements may be limited in terms of time and/or amount, and in some instances, the Company may have recourse against third parties for certain payments made by it under these agreements.
	It is not possible to predict the maximum potential amount of future payments that may be required under these or similar agreements due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material effect on its business, financial condition, cash flows or results of operations.
	Product warranties
	The Company warrants its products to be free of defects generally for a period of three years. The Company estimates its warranty costs based on historical warranty claim experience and includes such costs in cost of revenues. Warranty costs were not significant for the three months or six months ended September 30, 2013 or 2012.
	Legal proceedings
	In March 2011, Cypress Semiconductor Corporation, a semiconductor manufacturer, filed a lawsuit against the Company in the United States District Court for the District of Minnesota alleging that the Company's products, including its SigmaDDR and SigmaQuad families of Very Fast SRAMs, infringe five patents held by Cypress.  The complaint seeks unspecified damages for past infringement and a permanent injunction against future infringement.
	On June 10, 2011, Cypress filed a complaint against the Company with the United States International Trade Commission (the “ITC”).  The ITC complaint, as subsequently amended, alleged infringement by the Company of three of the five patents involved in the District Court case and one additional patent and also alleged infringement by three of our distributors and 11 of our customers who allegedly incorporate our SRAMs in their products.  The ITC complaint sought a limited exclusion order excluding the allegedly infringing SRAMs, and products containing them, from entry into the United States and permanent orders directing the Company and the other respondents to cease and desist from selling or distributing such products in the United States.  On July 21, 2011, the ITC formally instituted an investigation in response to Cypress's complaint.   On June 7, 2013, the ITC announced that the full Commission had affirmed the determination of Chief Administrative Judge Charles E. Bullock that GSI’s SRAM devices, and products containing them, do not infringe the Cypress patents and that Cypress had failed to establish existence of a domestic industry that practices the patents.  Moreover, the Commission reversed a portion of Judge Bullock’s determination with respect to the validity of the patents, finding the asserted claims of one of the patents to have been anticipated by prior art and, therefore, invalid.  The Commission ordered the investigation terminated, and Cypress did not appeal the ruling.
	The Minnesota District Court case had been stayed pending the conclusion of the ITC proceeding. Following the termination of the ITC investigation, the stay was lifted.  On May 1, 2013, Cypress filed an additional lawsuit in the United States District Court for the Northern District of California alleging infringement by our products of five additional Cypress patents.  Like the Minnesota case, the complaint in the California lawsuit seeks unspecified damages for past infringement and a permanent injunction against future infringement.  The Company filed answers in both cases denying liability and asserting affirmative defenses.  On August 7, 2013, the parties stipulated that the claims in the Minnesota case with respect to three of the asserted patents would be dismissed without prejudice and that the claims with respect to the remaining two patents would be transferred to, and consolidated with, the California case.  On August 20, 2013, the Court in the California case ordered the cases consolidated.  Discovery in the case is proceeding.
	The Company believes that it has strong defenses against Cypress’ patent infringement claims and intends to continue to defend itself vigorously. However, the litigation process is inherently uncertain, and the Company may not prevail.  Patent litigation is particularly complex and can extend for a protracted period of time, which can substantially increase the cost of such litigation.  The Company has not recorded any loss contingency during fiscal 2011, fiscal 2012 or fiscal 2013 in connection with these legal proceedings as the Company cannot predict their outcome and cannot estimate the likelihood or potential dollar amount of any adverse results.  However, an unfavorable outcome in these proceedings could have a material adverse impact on the Company's financial position, results of operations or cash flows for the period in which the outcome occurs and in future periods.

	Total		$	563			$	560			$	1,128			$	1,122
	As stock-based compensation expense recognized in the Condensed Consolidated Statement of Operations is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures in accordance with authoritative guidance.  The Company estimates forfeitures at the time of grant and revises the original estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
	The Company recognized related income tax benefits of $29,000 and $26,000, respectively, for the three months ended September 30, 2013 and 2012, and of $46,000 and $116,000, respectively, for the six months ended September 30, 2013 and 2012.  Windfall tax benefits realized from exercised stock options were $226,000 and $1,000, respectively, for the three months ended September 30, 2013 and 2012 and $403,000 and $7,000, respectively, for the six months ended September 30, 2013 and 2012.  Compensation cost capitalized within inventory at September 30, 2013 was insignificant. As of September 30, 2013, the Company’s total unrecognized compensation cost was $4.2 million, which will be recognized over a weighted average period of 2.19 years.  The Company calculated the fair value of stock-based awards in the periods presented using the Black-Scholes option pricing model and the following weighted average assumptions:

Accounting Policies [Abstract]	'
Basis of presenation	'
	Basis of presentation
	The accompanying unaudited condensed consolidated financial statements of GSI Technology, Inc. and its subsidiaries (“GSI” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission.  Accordingly, the interim financial statements do not include all of the information and footnotes required by generally accepted accounting principles for annual financial statements.  These interim financial statements contain all adjustments (which consist of only normal, recurring adjustments) that are, in the opinion of management, necessary to state fairly the interim financial information included therein.  The Company believes that the disclosures are adequate to make the information not misleading.  However, these financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2013.
	The consolidated results of operations for the three months ended September 30, 2013 are not necessarily indicative of the results to be expected for the entire fiscal year.

Litigation and settlement costs	'
	Litigation and settlement costs
	From time to time, the Company is involved in legal actions. The Company currently is a party to pending legal proceedings which it is defending aggressively.  See Note 6 for additional information regarding this pending litigation.  There are many uncertainties associated with any litigation, and the Company may not prevail.  The litigation, regardless of its eventual outcome, will be costly and time consuming and, should the outcome be adverse to the Company, could result in the Company being required to pay significant monetary damages.  If that occurs, our business, financial condition and results of operations could be materially and adversely affected. If information becomes available that causes us to determine that a loss in any of our pending litigation, or the settlement of such litigation, is probable, and we can reasonably estimate the loss associated with such events, we will record the loss in accordance with GAAP. However, the actual liability in any such litigation may be materially different from our estimates, which could require us to record additional costs.
