Abstract
A value of a temporal metric associated with valid data stored at a victim management unit (MU) is identified. The temporal metric reflects at least one of: a time after programming associated with the valid data, a number of valid accesses of the victim MU, a frequency of accesses of the valid data, a number of times the valid data has been written, or a timestamp indicating a most recent access of the valid data. A target cursor associated with the value of the temporal metric is identified. The valid data is associated with the target cursor.
Claims20
A system comprising:
- a memory device;
- and
- a processing device, operatively coupled to the memory device, to perform operations comprising:
- identifying a value of a temporal metric associated with valid data stored at a victim management unit (MU), wherein the temporal metric reflects at least one of:
- a time after programming associated with the valid data, a number of valid accesses of the victim MU, a frequency of accesses of the valid data, a number of times the valid data has been written, or a timestamp indicating a most recent access of the valid data;
- identifying a target cursor associated with the value of the temporal metric;
- and
- associating the valid data with the target cursor.
A method comprising:
- identifying a value of a temporal metric associated with valid data stored at a victim management unit (MU), wherein the temporal metric reflects at least one of:
- a time after programming associated with the valid data, a number of valid accesses of the victim MU, a frequency of accesses of the valid data, a number of times the valid data has been written, or a timestamp indicating a most recent access of the valid data;
- identifying a target cursor associated with the value of the temporal metric;
- and
- associating the valid data with the target cursor.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
- identifying a value of a temporal metric associated with valid data stored at a victim management unit (MU), wherein the temporal metric reflects at least one of:
- a time after programming associated with the valid data, a number of valid accesses of the victim MU, a frequency of accesses of the valid data, a number of times the valid data has been written, or a timestamp indicating a most recent access of the valid data;
- identifying a target cursor associated with the value of the temporal metric;
- and
- associating the valid data with the target cursor.
