Abstract
A resistive-switching random access memory device includes a memory cell disposed between a bit line and a word line, the memory cell having a resistive-switching element () and a Schottky diode (). The Schottky diode () and the resistive-switching element () are connected in series. The Schottky diode () includes a metal layer and a semiconductor layer contacting each other. An interface between the metal layer and the semiconductor layer has a non-planar shape.
