METHOD AND APPARATUS TO PERFORM CYCLIC REDUNDANCY CHECK TRAINING IN A MEMORY MODULE

Abstract:

A differential Data Strobe (DQS) signal is used to transmit and receive Cyclic Redundancy Check (CRC) between a host memory controller and a memory module. The differential DQS strobe signal is trained before it is used for transactions. The training is performed by sending and receiving a CRC pattern on the differential DQS strobe signal between the host memory controller and a buffer in the memory module.
