Abstract
A storage device with a memory may utilize an optimized read retry operation. A read retry table includes a number of read retry cases with updated read thresholds. The read thresholds in the read retry table may be used to avoid errors caused by shifting of charge levels. The optimization of read retry includes weighting or reordering of the read retry cases in the read retry table. The selection of a read retry case (and corresponding read thresholds) are determined based on the weighting or reordering.
