摘要

PROBLEM TO BE SOLVED: To provide a random number generator capable of generating natural random numbers using spin-orbit torque (SOT).SOLUTION: A random number generator of the present disclosure comprises a ferromagnetic metal layer, and spin-orbit torque wiring extending in a first direction crossing a lamination direction of the ferromagnetic metal layer and being bonded to the ferromagnetic metal layer. A direction of spins injected into the ferromagnetic metal layer from the spin-orbit torque wiring crosses an easy magnetization direction of the ferromagnetic metal layer.SELECTED DRAWING: Figure 1
