Patent ID: 8897084

Claim:
An apparatus, comprising: a memory interface circuit configured to determine an initial time value for capturing data from a memory based on a data strobe signal, wherein the memory interface circuit is configured to determine the initial time value by: issuing a single request for performance of a read operation in which a known value is to be retrieved from the memory; performing a plurality of data captures at different respective time offsets during the read operation; comparing the plurality of data captures with a copy of the known value; and based on the comparing, selecting one of the different respective time offsets as the determined initial time value; and wherein the memory interface circuit is configured to determine an adjusted time value for capturing the data, wherein the memory interface circuit is configured to determine the adjusted time value by using the initial time value to sample the data strobe signal, and the memory interface circuit is further configured to determine the adjusted time value without performance of a read operation in which a known value is retrieved from the memory.
