Abstract
Systems and methods for improving memory cell sensing margins by utilizing an optimal reference stimulus. A stimulus component applies a plurality of different reference 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 serially applied plurality of different reference stimuli. An analysis component computes an optimal reference stimulus by selecting one of the plurality of different reference stimuli, the one of the plurality of different reference stimuli associated with an absolute minima of number of memory cell characteristics that changed state as a function of the applied plurality of different reference stimuli.
