Zusammenfassung:Circuitry and methods of operating the same to strobe a DQ signal with a gated DQS signal are described. Some aspects are directed to a gating scheme to selectively pass a received strobe signal such as a DQS strobe signal based on a state of a drive enable (DE) signal in a drive circuit in the ATE, such that edges generated by the drive circuit are prevented from mistakenly strobing a received data signal such as a DQ signal.
