Abstract
A memory manager of a processor identifies a block of data for eviction from a first memory module to a second memory module. In response, the processor copies only those portions of the data block that have been identified as modified portions to the second memory module. The amount of data to be copied is thereby reduced, improving memory management efficiency and reducing processor power consumption.
