Abstract
A neuromorphic system and a memory device are provided. The neuromorphic system includes input neurons that provide input signals, output neurons that provide output signals, and a plurality of synapse units provided at interconnecting points between the input neurons and the output neurons. Each of the synapse units has a structure in which a plurality of synapse elements are connected in parallel to each other between one input neuron among the input neurons and one output neuron among the output neurons. Both of a multi-level operation and information retention are satisfied. The weight of a synapse unit is gradually and symmetrically changed. The synapse elements are stacked in a 3D stack structure, thereby increasing the number of levels, which is able to be implemented, and thereby representing a high degree of integration.
