Abstract
A method for calibrating a data valid window including the steps of: (A) setting a base delay of one or more datapaths to a predetermined value, (B) determining an optimum offset delay value for each of the one or more datapaths based upon actual memory accesses and (C) delaying a read data strobe signal based upon the base delay and the optimum offset delay value for each of the one or more datapaths.
