Abstract:
1. A nonvolatile memory apparatus comprising: (A) a first insulating layer; (B) a second insulating layer on the first insulating layer, the second insulating layer having a first concavity a bottom surface of which extends to the first insulating layer; (C) a plurality of electrodes in the first insulating layer each having a top surface which is exposed at the bottom surface of the first concavity; (D) a resistance change layer that lines a side wall and the bottom surface of the concavity; (E) an ion source material layer that fills space defined within the first concavity that is surrounded by the resistance change layer in the concavity, the ion source material layer having a second concavity therein that extends from a top surface thereof toward the bottom surface of the first concavity; and (F) a conductive material layer within the second concavity, wherein
