Abstract
Apparatus, method, and system for efficiently identifying and tracking cold memory pages are disclosed. The apparatus in one embodiment includes one or more processor cores to access memory pages stored in the memory by issuing access requests to the memory and a page index bitmap to track accesses made by the one or more processor cores to the memory pages. The tracked accesses are usable to identify infrequently-accessed memory pages, where the infrequently-accessed memory pages are removed from the memory and stored in a secondary storage.
