Claim 12:
13. A method for controlling access of a host controller to a memory module, the method comprising:
receiving, by a central buffer, a command/address signal from the host controller;
determining, by the central buffer, whether the command/address signal conforms to an authority management rule and configuring a buffer control command based on the determination result, so that the buffer control command indicates whether to restrict access of the host controller to the memory module; and
selectively restricting, by a data buffer, access of the host controller to the memory module based on the buffer control command;
wherein the buffer control command includes a plurality of time-sequenced fields, and a second field or a field after the second field of the plurality of time-sequenced fields in the buffer control command is configured by the central buffer based on the determination result.
