Abstract
A data structure is generated that identifies a shape of a valley that is located between programming distributions of the memory component. The data structure identifies read level thresholds at the valley associated with a logical page type of the memory component. For each of the read level thresholds the data structure associates a respective error count. A read level threshold is estimated using the data structure. A read operation is performed at the memory component using the read level threshold identified using the data structure.
