US Patent 10090461 Oxide-based three-terminal resistive switching logic devices

Oxide-based three-terminal resistive switching logic devices and methods of fabricating oxide-based three-terminal resistive switching logic devices are described. In a first example, a three-terminal resistive switching logic device includes an active region disposed above a substrate. The active region includes an active oxide material region disposed directly between a metal source region and a metal drain region. The device also includes a gate electrode disposed above the active oxide material region. In a second example, a three-terminal resistive switching logic device includes an active region disposed above a substrate. The active region includes a first active oxide material region spaced apart from a second oxide material region. The device also includes metal input regions disposed on either side of the first and second active oxide material regions. A metal output region is disposed between the first and second active oxide material regions.
