Neuromorphic device for parallel processing of spike signals

Abstract

A neuromorphic device comprises a synaptic array including a plurality of word lines and bit lines and including a plurality of synaptic elements coupled to intersections of each of the word lines and the bit lines, a word line signal output unit that sequentially outputs a plurality of word line signals for activating the word lines, a signal pre-processing unit that preprocesses a spike signal to modulates the spike signal into an input signal, a weight summation unit including a plurality of weight summation circuits that respectively output a plurality of output signals obtained by applying respective weighted values stored in the synaptic array to a plurality of input signals input through the signal pre-processing unit, and a data output unit that transmits the output signals output by the weight summation unit respectively to a plurality of output neurons in response to the word line signal.
