Abstract
A nonvolatile memory device having two or more resistors and methods of forming and using the same. A nonvolatile memory device having two resistance layers, and more particularly, to a nonvolatile memory device formed and operated using a resistance layer having memory switching characteristics and a resistance layer having threshold switching characteristics. The nonvolatile semiconductor memory device may include a lower electrode; a first resistance layer having at least two resistance characteristics formed on the lower electrode, a second resistance layer having threshold switching characteristics formed on the first resistance layer, and an upper electrode formed on the second resistance layer.
