Abstract
A memory controller outputs a clock signal to first and second DRAMs disposed on a memory module, the clock signal requiring respective first and second time intervals to propagate to the first and second DRAMs. The memory controller outputs a write command to be sampled by the first and second DRAMs at times indicated by the first clock signal and outputs, in association with the write command, first and second write data to the first and second DRAMs, respectively. The memory controller further outputs first and second strobe signals respectively to the first and second DRAMs, the first strobe signal to time reception of the first and second write data therein. The memory controller adjusts respective transmission times of the first and second strobe signals to be offset from one another by a time interval that corresponds to a difference between the first and second time intervals.
