Abstract

A system for providing system level sleep state power savings includes a plurality of memory channels and corresponding plurality of memories coupled to respective memory channels. The system includes one or more processors operative to receive information indicating that a system level sleep state is to be entered and in response to receiving the system level sleep indication, moves data stored in at least a first of the plurality of memories to at least a second of the plurality of memories. In some implementations, in response to moving the data to the second memory, the processor causes power management logic to shut off power to: at least the first memory, to a corresponding first physical layer device operatively coupled to the first memory and to a first memory controller operatively coupled to the first memory and place the second memory in a self-refresh mode of operation.
