Abstract
According to an embodiment, a pattern matching device includes unit cells, a circuit, and a measuring unit. Each unit cell includes a first magnetization reversal element used to store input data and including a first magnetic layer in which a direction of magnetization is variable, a second magnetization reversal element used to store template data and including a second magnetic layer in which a direction of magnetization is variable, and a spin-torque oscillator provided therebetween. The circuit applies a current to a selected spin-torque oscillator to acquire a high frequency signal from the selected spin-torque oscillator. The measuring unit measures a degree of matching between the input data and the template data based on the high frequency signal.
