3-terminal resistive switching device based integrate-and-fire neuron circuit and operation method thereof

摘要

Disclosed are a three-terminal resistance change element-based firing-type neuron circuit capable of constructing a neuron circuit without including a capacitor, and an operating method thereof. This does not include a conventional storage battery occupying a large area, but instead of a capacitor, a resistance change element formed of three terminals whose conductivity changes according to an input signal is used so that the conductivity of the element corresponds to the membrane potential corresponding to the voltage of the capacitor, thereby simplifying the accumulation process. can be imitated In addition, in general, since the three-terminal resistance change element has a characteristic that the conductivity returns to its original state over time, it is also possible to simulate the leakage characteristic in which the membrane potential decreases with time. Therefore, it is possible to design a highly integrated neuronal circuit through this.
