Abstract: A level count disparity is determined based at least in part on: (1) an expected count of a plurality of cells in solid state storage and (2) an observed count of the plurality of cells in the solid state storage, where the observed count is associated with a number of cells in the solid state storage that are activated by performing a single read on the solid state storage using a previous read threshold. A next read threshold is determined, including by: determining a direction relative to the previous read threshold based at least in part on the level count disparity and independent of the second and earlier level count disparity; and determining a magnitude based at least in part on the level count disparity and the second and earlier level count disparity. Read data is obtained using the next read threshold and error correction decoding is performed.
