Abstract: Systems, apparatuses, and methods for accessing and managing memories are disclosed herein. In one embodiment, a system includes at least first and second processors and first and second memories. The first processor maintains a request log with entries identifying requests that have been made to pages stored in the second memory. The first processor generates an indication for the second processor to process the request log when the number of entries in the request log reaches a programmable threshold. The second processor dynamically adjusts the programmable threshold based on one or more first conditions. The second processor also processes the request log responsive to detecting the indication. Additionally, the second processor determines whether to migrate pages from the second memory to the first memory based on one or more second conditions.
