Abstract
Techniques are disclosed relating to determining when a data strobe signal is valid for capturing data. In one embodiment, an apparatus is disclosed that includes a memory interface circuit configured to determine an initial time value for capturing data from a memory based on a data strobe signal. In some embodiments, the memory interface circuit may determine this initial time value by reading a known value from memory. In one embodiment, the memory interface circuit further configured to determine an adjusted time value for capturing the data, where the memory interface circuit is configured to determine the adjusted time value by using the initial time value to sample the data strobe signal.
