Abstract
Methods and integrated circuit devices for accelerating memory page classification 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. Classification of memory pages as hot or cold pages may be performed by an integrated circuit device that reads counter values that count transactions to corresponding memory pages. A distribution of counter values may be determined, and memory pages may be identified as hot or cold memory pages based on thresholds applied to the distribution.
