Abstract
We propose a novel neuron device based on resistive random access memory (ReRAM) and its application to neuromorphic pulse coding. Based on a mathematical neuron model, the Carrillo–Hoppensteadt model, we designed a neuron device that utilizes unipolar operation of ReRAMs effectively. We verified the fundamental operations of the proposed neuron device, an excitatory mode and an oscillatory mode, through Simulation Program with Integrated Circuit Emphasis simulations using a behavior model of ReRAMs. It was found that our neuron device can perform the coincidence detection and the pre-stimulus inhibition in response to pulse trains, supporting to neuromorphic pulse coding in the time domain.
