Oxide based nanoscale analog synapse device for neural signal recognition system

Abstract

We report oxide based analog synpase for neuromorphic system. By optimizing redox reaction at the metal/oxide interface, we can obtain stable analog synapse characteristics and wafer scale switching uniformity. We have confirmed the feasibility of neuromorphic hardware system with oxide synapse array device which recognizes the electroencephalogram (EEG) signal and rat's neural signal.
