Notes to financial statements [Abstract]
Stockholders' Equity	Note 15 - Stockholders' Equity Stock Repurchase Program Our Board of Directors has authorized us, subject to certain specifications, to repurchase shares of our common stock up to an aggregate maximum amount of $2.7 billion through May 2013. The repurchases will be made from time to time in the open market, in privately negotiated transactions, or in structured stock repurchase programs, and may be made in one or more larger repurchases, in compliance with Rule 10b-18 of the Securities Exchange Act, subject to market conditions, applicable legal requirements, and other factors. The program does not obligate NVIDIA to acquire any particular amount of common stock and the program may be suspended at any time at our discretion. As part of our share repurchase program, we have entered into, and we may continue to enter into, structured share repurchase transactions with financial institutions. These agreements generally require that we make an up-front payment in exchange for the right to receive a fixed number of shares of our common stock upon execution of the agreement, and a potential incremental number of shares of our common stock, within a pre-determined range, at the end of the term of the agreement. We did not enter into any structured share repurchase transactions or otherwise purchase any shares of our common stock during the three and six months ended July 31, 2011. Through July 31, 2011, we have repurchased an aggregate of 90.9 million shares under our stock repurchase program for a total cost of $1.46 billion. As of July 31, 2011, we are authorized, subject to certain specifications, to repurchase shares of our common stock up to $1.24 billion through May 2013. Convertible Preferred Stock As of July 31, 2011 and January 30, 2011, there were no shares of preferred stock outstanding. Common Stock We are authorized to issue up to 2,000,000,000 shares of our common stock at $0.001 per share par value.
