Abstract
Systems and methods are disclosed including a processing device operatively coupled to memory device. The processing device performs operations comprising receiving a memory access command specifying a logical address; determining a physical address associated with the logical address; determining a portion of the memory device that is referenced by the physical address; determine an endurance factor associated with the portion; and increasing, by a value derived from the endurance factor, a media management metric associated with a management unit of the memory device, wherein the management unit is referenced by the physical address.
Claims17
A system comprising:
- a memory device;
- and
- a processing device, operatively coupled with the memory device, to perform operations comprising:
- receiving a memory access command specifying a logical address;
- determining a physical address associated with the logical address;
- determining a portion of the memory device that is referenced by the physical address;
- determine an endurance factor associated with the portion;
- and
- increasing a media management metric associated with the physical address based on a value generated using the endurance factor and based on a read factor associated with a weight of read operations as compared to write operations.
A method comprising:
- receiving, by a processor, a memory access command specifying a logical address;
- determining a physical address associated with the logical address;
- determining a portion of a memory device that is referenced by the physical address;
- determine an endurance factor associated with the portion;
- generating a value as a function of the endurance factor by generating a random number within a specified range and determining whether the random number exceeds another function of the random number and the endurance factor;
- and
- in response to the value satisfying a threshold criterion, increasing a media management metric associated with a management unit of the memory device, wherein the management unit is referenced by the physical address.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device operatively coupled to a memory device, performs operations comprising:
- receiving a memory access command specifying a logical address;
- determining a physical address associated with the logical address;
- determining a portion of the memory device that is referenced by the physical address;
- determine an endurance factor associated with the portion;
- and
- increasing a media management metric associated with the physical address based on a value generated using the endurance factor and based on a read factor associated with a weight of read operations as compared to write operations.
