Abstract
A data structure that identifies a characteristic of a region that is located between programming distributions of the memory device and that corresponds to read level thresholds at the region is determined. An estimator type is selected from a plurality of estimator types corresponding with the data structure. A read level threshold of the read level thresholds is estimated using the selected estimator type. A read operation is performed at the memory device using the read level threshold estimated using the selected estimator type.
Claims20
A system comprising:
- a memory device;
- and
- a processing device, operatively coupled with the memory device, to perform operations comprising:
- determining a data structure that identifies a characteristic of a region that is located between programming distributions of the memory device and that corresponds to a plurality of read level thresholds at the region;
- selecting an estimator type from a plurality of estimator types corresponding with the data structure;
- estimating a read level threshold of the plurality of read level thresholds using the selected estimator type;
- and
- performing a read operation at the memory device using the read level threshold estimated using the selected estimator type.
A method, comprising:
- determining, by a processing device, a data structure that identifies a characteristic of a region that is located between programming distributions of a memory device and that corresponds to a plurality of read level thresholds at the region;
- selecting an estimator type from a plurality of estimator types corresponding with the data structure;
- estimating a read level threshold of the plurality of read level thresholds using the selected estimator type;
- and
- performing a read operation at the memory device using the read level threshold estimated using the selected estimator type.
A non-transitory computer-readable medium comprising instructions that, responsive to execution by a processing device, cause the processing device to perform operations comprising:
- determining a data structure that identifies a characteristic of a region that is located between programming distributions of a memory device and that corresponds to a plurality of read level thresholds at the region;
- selecting an estimator type from a plurality of estimator types corresponding with the data structure;
- estimating a read level threshold of the plurality of read level thresholds using the selected estimator type;
- and
- performing a read operation at the memory device using the read level threshold estimated using the selected estimator type.
