/ Neuromorphic devices with excitatory and inhibitory functionality

摘要

The present invention relates to a reconfigurable synaptic mimic element. The synapse mimic element includes first and second lower electrodes (BG1 and BG2) formed electrically isolated on a substrate, a first lower insulating film stack formed at least on a surface of the first lower electrode, First and second semiconductor regions formed on the first and second lower insulating film stacks, first and second semiconductor regions formed on the first and second lower insulating film stacks, first, second and third doped regions formed on the right and left sides of the first and second lower electrodes, And an upper insulating layer stack formed on the second semiconductor region and the first, second, and third doped regions, and an upper electrode formed on the upper insulating layer stack. The synapse mimic element according to the present invention can reconstruct a specific synapse mimic element to have a suppression or excitation function arbitrarily using first and second lower electrodes and a lower insulating layer stack including a charge storage layer formed on the surfaces of the first and second lower electrodes.
