Abstract
A method for calibrating read data strobe gating including the steps of: (A) performing a coarse timing adjustment configured to determine a coarse delay setting that produces invalid data, (B) performing a medium timing adjustment configured to adjust a medium delay setting and the coarse delay setting until valid data is detected, (C) performing a fine timing adjustment configured to adjust the medium delay setting and a fine delay setting until valid data is detected and (D) adding one-half cycle to a gating delay determined by the coarse, the medium and the fine delay settings.
