    摘要: A storage apparatus includes a plurality of first wiring layers extending in one direction, a plurality of second wiring layers extending in another direction, and a plurality of memory cells provided in respective opposing regions in which the plurality of first wiring layers and the plurality of second wiring layers are opposed to each other. The plurality of memory cells each includes a selector element layer, a storage element layer, and an intermediate electrode layer provided between the selector element layer and the storage element layer. One or more of the selector element layer, the storage element layer, and the intermediate electrode layer is a common layer that is common between the plurality of memory cells, in which the plurality of memory cells is adjacent to each other and extends in the one direction or the other direction. The intermediate electrode layer includes a nonlinear resistive material.

    摘要: A switch device according to an embodiment of the technology includes a first electrode, a second electrode that is disposed to face the first electrode, and a switch layer that is provided between the first electrode and the second electrode. The switch layer contains a chalcogen element. The switch layer includes a first region and a second region which have different composition ratios of one or more of chalcogen elements or different types of the one or more of chalcogen elements. The first region is provided close to the first electrode. The second region is provided closer to the second electrode than the first region.

    摘要: A storage device includes a first electrode, a second electrode, and a storage layer. The second electrode is disposed to oppose the first electrode. The storage layer is provided between the first electrode and the second electrode, and includes one or more chalcogen elements selected from tellurium (Te), selenium (Se), and sulfur (S), transition metal, and oxygen. The storage layer has a non-linear resistance characteristic, and the storage layer is caused to be in a low-resistance state by setting an application voltage to be equal to or higher than a predetermined threshold voltage and is caused to be in a high-resistance state by setting the application voltage to be lower than the predetermined threshold voltage to thereby have a rectification characteristic.
