A self-resetting phase-change neuron

Abstract

Neuromorphic, or brain-like, computing applications of phase-change devices have to date concentrated primarily on the implementation of phase-change synapses. However, a phase-change device can also mimic the integrative properties of a biological neuron. Here we demonstrate, using both physical and circuit modelling, that by combining a phase-change memory device with a simple external circuit we can readily deliver a self-resetting spiking phase-change neuron.
