Classifying access frequency of a memory sub-system component

Abstract:

A system detects a request for an access operation relating to an address of a component of a memory sub-system, determines a number of access operations pertaining to the particular address using at least one of a plurality of counters. The plurality of counters comprises an extended counter corresponding to an extended period of time and a recent counter corresponding to a recent period of time. The system assigns an access frequency classification to at least one of the address or the component of the memory sub-system based on the number of access operations pertaining to the particular address.
