Patent ID: 8754391

Claim:
A nonvolatile memory device, comprising: a first interlayer insulating film; a second interlayer insulating film on the first interlayer insulating film, the first and second interlayer insulating films separated from each other; a first electrode penetrating through or extending adjacent to the first interlayer insulating film and the second interlayer insulating film; a resistance change film on a top surface of the first interlayer insulating film and a bottom surface of the second interlayer insulating film and adjacent a side surface of the first electrode; a second electrode between the first interlayer insulating film and the second interlayer insulating film; and a two-way diode between the first electrode and the second electrode, wherein the diode is on the top surface of the first interlayer insulating film and the bottom surface of the second interlayer insulating film and is adjacent to at least one of the side surface of the first electrode and a side surface of the second electrode.
