Abstract
A method, non-transitory computer readable medium and circuit for gating a strobe (DQS) signal are disclosed. The method sends a read command to a memory, sends a strobe clock signal after the read command is sent and before the DQS signal is received from the memory, wherein the strobe clock signal comprises a duration equal to a duration of the DQS signal, gates the DQS signal based on the strobe clock signal to generate a positively gated strobe signal for indicating a rising edge of the DQS signal, wherein the gating is performed during a pre-amble of the DQS signal and generates a negatively gated strobe signal based on the positively gated strobe signal for indicating a falling edge of the DQS signal.
