Abstract
Parameters indicative of resistance variance of the memory elements are tracked. The resistance variance affects values of data stored in the resistance-based memory elements. A hash function is performed for each memory element. The hash function returns a reference to one of a plurality of counter elements. A value of each counter element is modified in response to the tracked parameter data of the associated memory element. Read operations affecting the memory elements are adjusted based on the values for the associated counter elements.
