Abstract
Disclosed are techniques for a memory buffer to track access to paged regions of a memory system at a configurable granularity finer than the size of the paged regions to provide more detailed statistics on memory access. The memory buffer may advertise its capabilities for fine-grained cold page tracking. The memory buffer may receive from the host information to configure a granularity of sub-regions of a paged region and a size of counters used to track access to the sub-regions. The memory buffer may track access requests to the sub-regions using the counters and to provide information on sub-region tracking to the host to identify individual hot or cold sub-regions. The host may make migration decisions for the paged regions with more granular information such as compaction of sub-regions to create a cold page or to treat each sub-region as a separately compressible entity to compress a mostly cold page.
