Abstract: A chip select signal is trained where the chip select signal is delayed to centrally align its pulses with a positive edge of a memory device's clock cycle. Over repeated iterations, the memory device stops its clock for an interval and a delayed pulse of the chip select signal is generated. The pulse delay is incrementally changed with each iteration. When the delay results in the trailing edge of the delayed pulse aligning with the positive edge of the last cycle before the stoppage interval, the memory device captures the contents of a computer bus, thus detecting a trailing edge delay value. When the delay results in the leading edge of the delayed pulse aligning with the positive edge of the last cycle, the device no longer captures the contents, thus detecting a leading edge delay value. A value between these values is then set as the optimal delay.
