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

摘要

Disclosed are a crossbar array element applicable to graph data analysis, a neuromorphic element including the same, an operating method of the crossbar array element, and a graph data analysis method using the crossbar array element. The disclosed crossbar array element applicable to graph data analysis may include 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 arranged 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-variable cells arranged in intersection regions remaining except for the diagonal among the plurality of intersection regions and having a rectifying characteristic and storing a changeable resistance state. The plurality of conductor cells may be arranged in intersection regions corresponding to a main diagonal in the plurality of intersection regions. The plurality of rectifying resistance-variable cells may be, for example, self-rectifying memristors.
