Abstract:
Disclosed is a system that comprises a memory device and a processing device, operatively coupled with the memory device, to perform operations that include, responsive to detecting a triggering event, selecting a family of memory blocks of the memory device, the selected family being associated with a set of bins, each bin associated with a plurality of read voltage offsets to be applied to base read voltages during read operations. The operations performed by the processing device further include calibration operations to determine data state metric values characterizing application of read voltage offsets of various bins. The operations performed by the processing device further include identifying, based on the determined data state metrics, a target bin and associating the selected family with the target bin.
