Abstract
Systems and methods for timing read operations with a memory device are provided. A timing signal is received from the memory device at a gating circuit. The timing signal is passed through as a filtered timing signal during a gating window. The gating window is configured to open the gating window based on a control signal and to close the gating window based on a falling edge of the timing signal. The falling edge is determined based on a counter that is triggered to begin counting by the control signal. The control signal is generated at a timing control circuit after receiving a read request from a memory controller. The timing control circuit is configured to delay generation of the control signal to cause the gating window to open during a preamble portion of the timing signal.
