Title:

NEUROMORPHIC DEVICE AND NEUROMORPHIC SYSTEM

Document Type and Number:

WIPO Patent Application WO/2022/091794

Kind Code:

A1

Abstract:

A neuromorphic device (300) for updating a weight between a first neuron (301) and a second neuron (303) that are interconnected. The neuromorphic device (300) is provided with a memdevice (302) having an electric characteristic that indicates a weight, a first weight update circuit (304a) and a second weight update circuit (304b). The first weight update circuit (304a) and the second weight update circuit (304b) change the electric characteristic of the memdevice (302) by a back propagation method using at least first data that is the output data of the first neuron (301) and second data that is the output data of the second neuron (303).
