Tracking accesses to a memory using a ring-buffer structure

Abstract

In some implementations, a memory system controller may receive, from a host system, a memory-access request. The memory system controller may store an identifier associated with the memory-access request in a ring-buffer structure. The memory system controller may determine whether a data structure includes an entry associated with the identifier. The memory system controller may perform one of: updating a memory-access counter stored at the entry when the data structure does include the entry, or creating the entry in the data structure and initializing the memory-access counter stored at the entry when the data structure does not include the entry. The memory system controller may receive, from the host system, a request to read the data structure and/or may transmit, to the host system and based on the request, an indication of a respective identifier and a respective memory-access counter for each entry having a respective flag set.
