    Abstract: A memory device is provided that includes a memory array having a plurality of reversible resistance-switching memory cells, and a memory controller coupled to the memory array. The memory controller is adapted to program a first reversible resistance-switching memory cell in the memory array to a predetermined data state, determine a program loop count associated with the program step, and retire the first reversible resistance-switching memory cell from further use for host data storage based on the associated program loop count.
