Abstract

Official abstract text for this publication.

A memory may include two electrodes and phase change material having an amorphous reset state and a partially crystalized set state, coupled between the two electrodes. The phase change material in the set state may have a highly nonlinear current-voltage response in a subthreshold voltage region. The phase change material may be an alloy of indium, antimony, and tellurium.
