Method and apparatus for refresh management of memory modules

摘要

One embodiment sets forth an interface circuit configured to manage refresh command sequences that includes a system interface adapted to receive a refresh command from a memory controller, dock frequency detection circuitry configured to determine the timing for issuing staggered refresh commands to two or more memory devices coupled to the interface circuit based on the refresh command received from the memory controller. and at least two refresh command sequence outputs configured to generate the staggered refresh commands for the two or more memory devices
