摘要：A system that calibrates timing relationships between signals involved in
performing write operations is described. This system includes a memory controllerwhich is coupled to a set of memory chips, wherein each memory chip includes a phasedetector configured to calibrate a phase relationship between a data-strobe signal and aclock signal received at the memory chip from the memory controller during a writeoperation. Furthermore, the memory controller is configured to perform one or morewrite-read-validate operations to calibrate a clock-cycle relationship between the data-strobe signal and the clock signal, wherein the write-read-validate operations involvevarying a delay on the data-strobe signal relative to the clock signal by a multiple of aclock period.
