Abstract:
1. A method for memory command throttling in a partitioned memory subsystem, comprising: accepting, by a master memory controller included in multiple memory controllers, a synchronization command, wherein the synchronization command includes command data that includes an associated synchronization indication for each of the multiple memory controllers, and wherein each of the multiple memory controllers controls a respective partition of the partitioned memory subsystem; in response to receiving the synchronization command, forwarding, by the master memory controller, the synchronization command to the multiple memory controllers; in response to receiving the forwarded synchronization command, de-asserting, by each of the multiple memory controllers, an associated status bit; in response to receiving the forwarded synchronization command, determining, by each of the multiple memory controllers, whether the associated synchronization indication is asserted; and transmitting, from each of the multiple memory controllers with the asserted associated synchronization indication, the forwarded synchronization command to associated power control logic.
