Disclosed is a system including a memory device having a plurality of physical cells and a processing device, operatively coupled with the memory device. The processing device maintains association of block families with a first (second, etc.) bin of a plurality of bins, each of the plurality of bins associated with one or more read voltage offsets. The read voltage offsets are used to compensate for a temporal read voltage shift caused by a charge loss by memory cells of the block families. Responsive to an occurrence of a power event, the processing device performs diagnostics of one or more blocks of various block families and determines whether to maintain association of the block families with current bins of the respective block families or to associate the block families with different bins.
