Abstract
Methods, systems, and devices for predictive media management for read disturb are described. A read disturbance manager can monitor a bit error rate for a block of a memory die. The read disturbance manager can detect that a degradation of the bit error rate satisfies a degradation threshold specific to the memory die. In some cases, the read disturbance manager can perform a write operation to write data from the block of the memory die to a second block of the memory die based on detecting that the degradation of the bit error rate satisfies the degradation threshold.
Claims20
A method, comprising:
- monitoring a bit error rate for a block of a memory die of a memory sub-system;
- determining, based at least in part on the monitoring, that a degradation of the bit error rate for the block of the memory die satisfies a degradation threshold specific to the memory die, the degradation threshold associated with read operations performed on the block of the memory die;
- and
- performing a write operation to write data from the block of the memory die to a second block of the memory die based at least in part on determining that the bit error rate satisfies the degradation threshold.
A system comprising:
- a plurality of memory components;
- and
- a processing device, operatively coupled with the plurality of memory components, to:
- detect that a bit error rate degradation for a block of a memory die satisfies a degradation threshold specific to the memory die, the degradation threshold associated with data recovery for the memory die;
- and
- write data from the block of the memory die to a second block of the memory die based at least in part on detecting that the bit error rate degradation satisfies the degradation threshold.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:
- monitor a bit error rate for a block of a memory die of a memory sub-system;
- determine, based at least in part on the monitoring, that a degradation of the bit error rate for the block of the memory die satisfies a degradation threshold specific to the memory die, the degradation threshold associated with read operations performed on the block of the memory die;
- and
- perform a write operation to write data from the block of the memory die to a second block of the memory die based at least in part on determining that the bit error rate satisfies the degradation threshold.
