Abstract: The application discloses a memory controller coupled between a memory module and a host controller to control accesses of the host controller to the memory module. The memory controller comprises a central buffer coupled between the memory module and the host controller via a command/address channel, wherein the central buffer is configured to receive a command/address signal from the host controller and provide the command/address signal to the memory module. The central buffer comprises: a recognition block coupled to the command/address channel to receive the command/address signal, wherein the recognition block is configured to generate access history information based on the received command/address signal; a compression block coupled to the recognition block to receive the access history information, wherein the compression block is configured to compress the access history information; and a transmission block, wherein the compressed access history information is transmitted out from the central buffer via the transmission block.
