Abstract
Methods and integrated circuit devices for recording memory-side page activity are provided. Memory systems typically have a combination of faster memory devices and slower memory devices. Frequently accessed memory pages (hot pages) should be maintained in the faster memory devices while less frequently accessed memory pages (cold pages) should be maintained in the slower memory devices. To determine the memory pages that should be moved between the faster memory devices and the slower memory devices, counters may be implemented to count transactions to the memory pages. The counter values may be periodically checked to identify memory pages that can be moved from faster memory devices to slower memory devices, and vice-versa.
