Abstract
A memory controller includes an interface to receive a data strobe signal and corresponding read data. The data strobe signal and the read data correspond to a read command issued by the memory controller, and the read data is received in accordance with the data strobe signal and an enable signal. A circuit in the memory controller is to dynamically adjust a timing offset between the enable signal and the data strobe signal, and control logic is to issue a supplemental read command in accordance with a determination that a time interval since a last read command issued by the memory controller exceeds a predetermined value.
