Abstract

An integrated circuit emulating a neural system and a fabricating method thereof are provided. A synapse device array that imitates a brain neural system (i.e., a central nervous system) requiring high integration on the same substrate is formed by stacking one or more layers on a lower portion, and a neuron circuit of a peripheral nervous system having sensory and motor neurons connected to the brain neural system is formed on an upper portion.
