Abstract
A method of fabricating a neuromorphic device includes forming a variable-resistance layer between a first terminal and a second terminal, the variable-resistance layer varies in resistance based on an oxygen concentration in the variable-resistance layer. The method further includes forming an electrolyte layer over the variable-resistance layer that is stable at room temperature and that conducts oxygen ions in accordance with an applied voltage. The method further includes forming a gate layer over the electrolyte layer to apply a voltage on the electrolyte layer and the variable-resistance layer, the gate layer formed using an oxygen scavenging material.
