WebThe present invention generally provides for adjusting a delay of the read data strobe signal DQS to approximately center the read data strobe signal DQS in the valid data eye window. For example, when the delay is too short, the read data strobe signal DQS is generally earlier than a minimum boundary of the valid data eye window (e.g., trace 140).
