Abstract
An apparatus is provided that includes a memory cell and a control circuit coupled to the memory cell. The memory cell includes a reversible resistance-switching memory element coupled in series with a selector element that has a threshold voltage. The control circuit is configured to use a first pulse having a first polarity to first access the memory cell, use a second pulse having a second polarity opposite the first polarity to second access the memory cell, and use a third pulse having the first polarity to third access the memory cell. The third pulse is configured to reduce a rate of threshold voltage drift of the selector element.
