Abstract
A level count disparity is determined based at least in part on an expected count of a plurality of cells in a solid state storage and an observed count of the plurality of cells in the solid state storage, where the observed count is obtained from a read performed on the solid state storage using a previous read threshold. A next read threshold is determined based at least in part on the level count disparity. A read is performed on the solid state storage using the next read threshold to obtain read data and error correction decoding is performed on the read data.
