Multi-level storage algorithm to emphasize disturb conditions

Abstract

Providing systems and methods that reduce memory device read errors and improve memory device reliability by intelligently disturbing the memory cells during storage of their characteristic states. A specification component can determine a desired characteristic state for each cell of a plurality of multi-cell memory devices. A storage component can, alternatively, successively store an equivalent characteristic state in each cell of the plurality of multi-cell memory devices in stages, based on a cell's current characteristic state, or directly store the desired characteristic state of each cell of the plurality of multi-cell memory devices, based on an ordering of desired characteristic states of cells of the multi-cell memory devices. Further, a step component can gradate the equivalent characteristic state between successive storage stages. In this way, the overlap of distributions of electrical characteristics associated with different bits of one or more memory cells can be reduced.
