Abstract
An apparatus includes a perpendicular magnetic tunnel junction (MTJ) including a free layer. The apparatus includes a spin orbit torque metal layer coupled to the perpendicular MTJ and configured to change a magnetization state of the free layer responsive to flow of a current along the spin orbit torque metal layer. The apparatus includes a random number generator configured to generate a random number at least partially based on a state of the perpendicular MTJ.
