Equity [Abstract]
Share Repurchase Programs	Share Repurchase Programs In June 2011, the Board authorized the purchase of up to $1,000 of company stock. This program has no expiration date, although the company suspended purchases under this program in July 2012. Approximately $750 remained available under this program as of October 28, 2012. The company also repurchases shares to offset the impact of dilution from shares issued under the company’s stock compensation plans. During the three-month period ended October 28, 2012, the company repurchased approximately 480 thousand shares at a cost of $17. During the three-month period ended October 30, 2011, the company repurchased 3 million shares at a cost of $85. Of this amount, $57 was used to repurchase shares pursuant to the company’s June 2011 publicly announced share repurchase program.
