Memory power management through high-speed intra-memory data transfer and dynamic memory address remapping

摘要

A method, circuit, and system are disclosed. In one embodiment, the method comprises designating a contiguous portion of the physical memory in one or more dual in-line memory modules (DIMMs) to be powered down, locking the designated portion of memory to halt memory operations between the memory and any device that requests access to the designated portion of memory, relocating any data currently residing in the designated portion of the one or more DIMMs to one or more locations in the non-designated portion of the one or more DIMMs, and powering down the designated portion of the one or more DIMMs.
