Abstract:
Systems and methods are provided for timing read operations with a memory device. A system for timing read operations with a memory device includes a gating circuit configured to receive a timing signal from the memory device. The gating circuit is further configured to pass through the timing signal as a filtered timing signal during a gating window. The gating window is generated by the gating circuit based on a control signal. The system further includes a timing control circuit configured to generate the control signal after receiving a read request from a memory controller. The timing control circuit is further configured to adjust the control signal to account for temporal variations in the timing signal from the memory device.
