Abstract
In a training mode, per-bit de-skew (PBDS) values for a datamask signal in a synchronous dynamic random access memory are iteratively adjusted in conjunction with writing test patterns to the memory and reading back test patterns from the memory until optimum datamask PBDS values are determined.
