UNIT, DEVICE AND METHOD FOR SIMULATING NEURONAL SYNAPSE OF BIONT

摘要

Disclosed are a unit, device and method for simulating a neuronal synapse of a biont based on a chalcogenide compound. The unit comprises a first electrode layer, a functional material layer and a second electrode layer. The first electrode layer receives a first pulse signal, and the second electrode layer receives a second pulse signal. A device can change the conductance thereof according to an input signal, so as to simulate the change of synapse weighting. When the difference value between the frequency of the first pulse signal and that of the second pulse signal is positive or negative, the change of conductance realizes the simulation of the function of spike frequency-dependent synapse plasticity of the neuronal synapse of the biont; and when the peak value of the signal difference between the first pulse signal and the second pulse signal is positive or negative, the change of the conductance realizes the simulation of the function of spike timing-dependent synapse plasticity of the neuronal synapse of the biont. The present invention can achieve the basic function of the neuronal synapse of the biont on a single inorganic device, and provide basic components forming an artificial neural network, and can achieve the effects of increasing the integration degree and reducing the power consumption.
