Abstract

A nonvolatile memory device and methods of manufacturing the same has one electrode with a higher work function and a second electrode with a lower work function. The nonvolatile memory device further comprises one or more resistive random access memory (RRAM) cells. The RRAM cells comprise a semiconductor layer with a bandgap of at least four electron volts and a barrier layer between the semiconductor layer and one of the electrodes.
