ABSTRACT:
A memory system includes a memory controller that writes data to and reads data from a memory device. A write data strobe accompanying the write data indicates to the memory device when the write data is valid, whereas a read strobe accompanying data from the memory device indicates to the memory controller when the read data is valid. The memory controller adaptively controls the phase of the write strobe to compensate for timing drift at the memory device. The memory controller uses the read strobe as a measure of the drift.
