ADAPTIVE APPLICATION OF VOLTAGE PULSES TO STABILIZE MEMORY CELL VOLTAGE LEVELS

Abstract:

A method is disclosed that includes causing a first set of a plurality of voltage pulses to be applied to memory cells of a memory device, a voltage pulse of the first set of the voltage pulses placing the memory cells of the memory device at a voltage level associated with a defined voltage state. The method also includes determining a set of bit error rates associated with the memory cells of the memory device in view of a data mapping pattern for the memory cells of the memory device, wherein the data mapping pattern assigns a voltage level associated with a reset state to at least a portion of the memory cells of the memory device. The method further includes determining whether to apply one or more second sets of the voltage pulses to the memory cells of the memory device in view of a comparison between the set of bit error rates for the memory cells and a previously measured set of bit error rates for the memory cells.
