Abstract
Systems and methods for extending the usable lifetime of memory cells by utilizing reference-free sampled sensing. A stimulus component applies a plurality of different stimuli to a plurality of memory cells of a memory device. A sense component senses a characteristic of each memory cell of the plurality of memory cells as a function of the applied plurality of different stimuli. An analysis component determines a logic state of each memory cell of the plurality of memory cells as a function of the sensed characteristic of each memory cell of the plurality of memory cells.
