Abstract
A memory controller for strobe-based memory systems is disclosed. The memory controller includes a circuit to generate a control signal having a predetermined timing relationship with respect to a first clock signal, a circuit to receive the control signal, and a receiver to sample the read data in response to the qualified read strobe signal. The receiving circuit includes an input to receive an external read strobe signal transmitted by a semiconductor memory device, circuitry to synchronize the control signal and the received read strobe signal to have a common timing relationship with respect to each other, and circuitry to gate the read strobe signal based on the synchronized control signal.
