APPARATUS HAVING INDICATIONS OF MEMORY CELL DENSITY AND METHODS OF THEIR DETERMINATION AND USE

摘要

Methods and apparatus utilizing indications of memory cell density facilitate management of memory density of a memory device. By permitting each of a plurality of portions of a memory array of the memory device to be assigned a corresponding memory cell density determined through an evaluation of those portions of the memory array, better performing portions of the memory array may not be hindered by lesser performing portions of the memory array.
