We develop an artificial naural network where analog spintronics memory devices are used as an artificial synapse. Using the developed network, we show a proof-of-concept demonstration of the associative memory operation, a representative function of human brains. We confirm the capability of the analog spin memory device to learn the information and store the results in a nonvolatile manner.
