Systems and Methods for Monitoring and Managing Memory Blocks to Improve Power Savings

摘要

Systems and methods are provided for placing a portion of a memory into a low power mode. A system includes a hot spot region creator configured to determine an activity level for each of a plurality of regions of a memory, where certain of the regions are determined to be active regions, and where certain of the regions are determined to be inactive regions and rearrange the data to position the active region data in a contiguous active portion of memory and to position the inactive regions data in a contiguous inactive portion of memory. A memory controller is configured to place the contiguous inactive portion of memory into a low power mode.
