Crossbar array device applicable to graph data analysis, nueromorphic device including the same, operation method of crossbar array device and graph data analysis method using crossbar array device

Abstract

Disclosed is a crossbar array device applicable to graph data analysis including a plurality of word lines extending in a first direction; a plurality of bit lines extending in a second direction intersecting the plurality of word lines; a plurality of conductor cells disposed in intersection regions corresponding to a diagonal among a plurality of intersection regions defined between the plurality of word lines and the plurality of bit lines; and a plurality of rectifying resistance change cells disposed in remaining intersection regions excluding the diagonal among the plurality of intersection regions, having a rectifying characteristic and storing a changeable resistance state.
