    摘要: A phase-change memory device includes a first insulator having a hole therethrough, a first electrode that conforms at least partially to the hole, a phase-change material in electrical communication with the first electrode, and a second electrode in electrical communication with the phase-change material. When current is passed from the first electrode to the second electrode through the phase-change material, at least one of the first and second electrodes remains unreactive with the phase change material.

    摘要: A method of programming a multi-layer chalcogenide electronic device. The device includes an active region in electrical communication with two terminals, where the active region includes two or more layers. The method includes providing an electrical signal between the two terminals, where the electrical signal alters an electrical characteristic of a layer remote from one of the terminals. In one embodiment, the layer remote from the terminal is a chalcogenide material and the electrical characteristic is resistance. In another embodiment, an electrical characteristic of the layer in contact with the terminal is also altered. The alteration of an electrical characteristic may be caused by a transformation of a chalcogenide material from one structural state to another structural state.

    摘要: A multi-layer chalcogenide, memory or switching device. The device includes an active region disposed between a first terminal and a second terminal. The active region includes a first layer and a second layer, where one of the layers is a heterogeneous layer that includes an operational component and a promoter component. The other layer may be a homogeneous or heterogeneous layer. In exemplary embodiments, the operational component is a chalcogenide or phase change material and the promoter component is an insulating or dielectric material. Inclusion of the promoter component provides beneficial performance characteristics such as a reduction in reset current or minimization of formation requirements.
