Abstract
It is determined whether a write disturb capability associated with a first location of a memory device satisfies a threshold criterion. Responsive to determining that the write disturb capability associated with the first location of the memory device satisfies the threshold criterion, a plurality of memory units is remapped to a second location of the memory device, wherein a write disturb capability associated with the second location of the memory device does not satisfy the threshold criterion.
Claims20
A system comprising:
- a memory device;
- and
- a processing device, operatively coupled with the memory device, to perform operations comprising:
- determining that a write disturb capability associated with a first location of the memory device satisfies a threshold criterion;
- and
- responsive to determining that the write disturb capability associated with the first location of the memory device satisfies the threshold criterion, remapping a plurality of memory units residing in the first location to a second location of the memory device, wherein a write disturb capability associated with the second location of the memory device does not satisfy the threshold criterion.
A method comprising:
- determining that a write disturb capability associated with a first location of a memory device satisfies a threshold criterion;
- and
- responsive to determining that the write disturb capability associated with the first location of the memory device satisfies the threshold criterion, remapping a plurality of memory units residing in the first location to a second location of the memory device, wherein a write disturb capability associated with the second location of the memory device does not satisfy the threshold criterion.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
- determining that a write disturb capability associated with a first location of a memory device satisfies a threshold criterion;
- and
- responsive to determining that the write disturb capability associated with the first location of the memory device satisfies the threshold criterion, remapping a plurality of memory units residing in the first location to a second location of the memory device, wherein a write disturb capability associated with the second location of the memory device does not satisfy the threshold criterion.
