    摘要: According to one embodiment, a memory device includes a first conductor layer and a second conductor layer spaced apart from each other in a first direction, a first semiconductor film spaced from the first conductor layer in a second direction intersecting the first direction, and a second semiconductor film spaced from the second conductor layer in the second direction. The first semiconductor film is between a first resistance change film and the first conductor layer in the second direction. The second semiconductor film is between a second resistance change film and the second conductor layer in the second direction. A first conductor film has a first end contacting the first semiconductor film and the first resistance change film and a second end contacting the second semiconductor film and the second resistance change film.

    摘要: A three terminal ReRAM device, which combines a Schottky barrier transistor and a Schottky barrier ReRAM into a single device is provided. The Schottky transistor memory device includes a source region, a drain region, and a gate electrode. Between the source and drain regions, the ReRAM material is present. The ReRAM material can include a metal oxide, such as zinc or hafnium oxide. A Schottky barrier forms naturally between the drain region and the ReRAM material. As voltage is applied to the gate electrode and the source region, the Schottky barrier breaks down, leading to the formation of a filament across the drain region and the ReRAM material. The filament is non-volatile and short-circuits the reverse-biased barrier, keeping the device in a low resistance state. The filament can be removed by reversing the polarity of the voltage such that the device switches back to a high resistance state.
