Abstract
Disclosed is a system including a memory timing calibration circuit to calibrate a strobe signal of a memory device and a method of calibrating the strobe signal. The memory timing calibration circuit includes a difference signal generator coupled to a strobe signal generator and an external control circuit. The difference signal generator is configured to generate a difference signal indicating a time difference between the strobe signal from the strobe signal generator and an external clock signal from the external control circuit. The memory timing calibration circuit further includes a delay circuit coupled to the difference signal generator and the external control circuit. The delay circuit is configured to generate a modified external clock signal by delaying the external clock signal by a delay determined based at least in part on the difference signal.
