Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective tax rate decreased to 21.7% for the three months ended November 30, 2019 from 23.3% for the three months ended November 24, 2018 primarily due to an increase in estimated research and development tax credits and excess tax benefits related to stock-based compensation in Fiscal 2020. We file a U.S. Federal tax return, as well as returns in various international and state jurisdictions. As of November 30, 2019, our federal returns from Fiscal 2016 to present are subject to review by the Internal Revenue Service. With limited exception, state returns from Fiscal 2015 to present continue to be subject to review by state taxing jurisdictions. We are currently under review by certain U.S. state tax authorities for Fiscal 2015 through 2018. We believe we have adequately reserved for our exposure to additional payments for uncertain tax positions in our liability for unrecognized tax benefits.
