Neural network with synapse string array

Abstract

Provided is a binary neural network including: a synapse string array in which multiple synapse strings are sequentially connected. The synapse string includes: first and second cell strings, each including memory cell devices connected in series; and switching devices connected to first ends of two-side ends of the first and second cell strings. The memory cell devices of the first and second cell strings are in one-to-on correspondence to each other, and a pair of the memory cell devices being in one-to-on correspondence to each other have one-side terminals electrically connected to each other to constitute one synapse morphic device. A plurality of the pairs of memory cell devices configured with the first and second cell strings constituting each synapse string constitute a plurality of the synapse morphic devices. The synapse morphic devices of each synapse string are electrically connected to the synapse morphic devices of other synapse strings.
