Abstract

A processing device coupled to the memory device can be configured to monitor respective raw bit error rates (RBERs) corresponding to a plurality of groups of memory cells of the memory device. The processing device can also be configured to responsive to determining that an RBER corresponding to a particular group of the plurality of groups of memory cells has met a criteria, adjust a read window budget corresponding to the particular group of memory cells.
