Abstract
A neuromorphic device includes a metal-oxide channel layer that has a variable-resistance between a first terminal and a second terminal. The neuromorphic device further includes a metal-oxide charge transfer layer over the metal-oxide channel layer that causes the metal-oxide channel layer to vary in resistance based on charge exchange between the metal-oxide charge transfer layer and the metal-oxide channel layer in accordance with an applied input signal. The neuromorphic device further includes a third terminal that applies the signal to the metal-oxide charge transfer layer and the metal-oxide channel layer.
