Abstract
A memory circuit includes a delay module receiving a strobe signal and producing a delayed strobe signal therefrom. The memory circuit also includes a calibration module that initiates recalibration of the delay module when the calibration module discerns that the delayed strobe signal is within a predetermined proximity of an edge of a reference signal. The memory circuit can be included in a memory interface. Furthermore, in some embodiments, a strobe signal can be used as the reference signal.
