Associative memory is one of the neuromorphic computing that compares an input data array with learning data arrays and associates the closest data array. The system has been studied with coupled oscillator network for physical implementation. In this study, we report associative memory by a feedforward network using spin torque oscillators. By utilizing the high-speed spin dynamics, we succeeded in processing the denoising task in a very short time of 300 ns.
