Abstract
Bit errors affecting cells of a solid-state, non-volatile memory are assigned to at least a first or a second category based on a relative amount of voltage shift that caused the respective bit errors in the respective cells. A reference voltage used to access the respective cells is adjusted to manage the respective bit errors of the first category. Additional corrective measures are taken to manage the respective bit errors of the second category.
