NEURAL NETWORK DEVICE AND SIGNAL PROCESSING METHOD

Abstract

A neural network device according to an embodiment includes a plurality of synapse circuits and a plurality of neuron circuits. Each of the synapse circuits acquires one or more spike signals output from one of the neuron circuits, and, in response to acquiring the spike signals, outputs a synaptic current with a current amount corresponding to an assigned synaptic weight and the spike signals. A first neuron circuit out of the neuron circuits outputs N spike signals as the one or more spike signals. The first neuron circuit includes a spike output circuit to output at least an n-th spike signal out of the N spike signals when the membrane potential is higher than an n-th threshold potential out of the N threshold potentials different from each other.
