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.
Claims20
A method, comprising:
- detecting a request for an access operation relating to an address of a component of a memory sub-system;
- determining, by a processing device, a number of access operations pertaining to the particular address using at least one of a plurality of counters, wherein the plurality of counters comprises an extended counter corresponding to a first number of access operations pertaining to the particular address over an extended period of time and a recent counter corresponding to a second number of access operations pertaining to the particular address over a recent period of time;
- and
- assigning 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.
A system, comprising:
- a memory device;
- and
- a processing device coupled to the memory device, to perform operations comprising:
- detecting a request for an access operation relating to an address of a component of a memory sub-system;
- determining a number of access operations pertaining to the particular address using at least one of a plurality of counters, wherein the plurality of counters comprises an extended counter corresponding to a first number of access operations pertaining to the particular address over an extended period of time and a recent counter corresponding to a second number of access operations pertaining to the particular address over a recent period of time;
- and
- assigning 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.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
- detecting a request for an access operation relating to an address of a component of a memory sub-system;
- determining a number of access operations pertaining to the particular address using at least one of a plurality of counters, wherein the plurality of counters comprises an extended counter corresponding to a first number of access operations pertaining to the particular address over an extended period of time and a recent counter corresponding to a second number of access operations pertaining to the particular address over a recent period of time;
- and
- assigning 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.
