SYSTEMS AND METHODS FOR DQS GATING

摘要

Systems and methods for timing read operations with a memory device are provided. A timing signal from the memory device is received at a gating circuit. The timing signal is passed through as a filtered timing signal during a gating window. The gating circuit is configured to open the gating window based on a control signal. The gating circuit is further configured to close the gating window based on a first edge of the timing signal. The first edge is determined based on a counter that is triggered to begin counting by the control signal. At a timing control circuit, the control signal is generated based on i) a count signal from the counter, and ii) a second edge of the timing signal that precedes the first edge in time.
