  • Phase change memory devices and methods of fabricating the same
    Patent number: 7834340
    Abstract: Phase change memory devices are provided including a selection element electrically connected to a phase change material pattern. The selection element includes a metallic conductor and a semiconductor that are in contact with each other. A depletion region in contact with a metallic pattern is generated in the semiconductor in an equilibrium state. The depletion region includes a high barrier region having an electric potential barrier higher than an interface electric potential barrier and a low barrier region having an electric potential barrier lower than the interface electric potential barrier. Related methods are also provided.
