Nonvolatile memory element having a variable resistance layer whose resistance value changes according to an applied electric signal
Abstract:
Provided is a nonvolatile memory element achieving a stable resistance change and miniaturization, and a method of manufacturing the same. The nonvolatile memory element includes: a first electrode formed above a substrate; an interlayer insulating layer formed above the substrate including the first electrode and having a memory cell hole reaching the first electrode; a barrier layer formed in the memory cell hole and composed of a semiconductor layer or an insulating layer connected to the first electrode; a second electrode formed in the memory cell hole and connected to the barrier layer; a variable resistance layer formed on the second electrode and having a stacked structure whose resistance value changes based on electric signals; and a third electrode connected to the variable resistance layer and formed on the interlayer insulating layer to cover the memory cell hole.
