Abstract
A memory controller identifies a predominant type of error of a memory unit of solid state memory cells. An error type differential is calculated. The error type differential is a difference between a number of charge loss errors and a number of charge gain errors of the memory unit. A Voffset error differential is calculated. The Voffset error differential is a difference between a number of errors of the predominant type at a first Voffset and a number of errors of the predominant type at a second Voffset. A Voffset is determined using a ratio of the error type differential and the Voffset error differential.
