Abstract
A group of cells in solid state storage is sampled in order to obtain a sampled distribution associated with the group of cells. An axis of symmetry is determined using the sampled distribution. At least some portion of a conditional distribution is determined based at least in part on: (1) the sampled distribution and (2) the axis of symmetry. An optimal read threshold is estimated using the sampled distribution and the conditional distribution.
