Abstract

A bit flip count is determined for each bin in a plurality of bins, including by: (1) performing a first read on a group of solid state storage cells at a first threshold that corresponds to a lower bound for a given bin and (2) performing a second read on the group of solid state storage cells at a second threshold that corresponds to an upper bound for the given bin. A minimum is determined using the bit flip counts corresponding to the plurality of bins and the minimum is used to estimate an optimal threshold.
