ESTIMATION OF READ LEVEL THRESHOLDS USING A DATA STRUCTURE

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.
