Abstract

A method of operating a memory controller is disclosed. The method includes transmitting data signals to a memory device over each one of at least two parallel data links. A timing signal is sent to the memory device on a first dedicated link. The timing signal has a fixed phase relationship with the data signals. A data strobe signal is driven to the memory device on a second dedicated link. Phase information is received from the memory device. The phase information being generated internal to the memory device and based on a comparison between the timing signal and a version of the data strobe signal internally distributed within the memory device. A phase of the data strobe signal is adjusted relative to the timing signal based on the received phase information.
