Abstract
Disclosed is logic device using spin orbit torque. Two magnetic tunnel junctions have mutually opposite magnetization directions. The direction of the current flowing through the non-magnetic metal layer acts as an input, and the resistance states of the magnetic tunnel junctions are determined by the input program currents. Various logic devices are implemented by a method of setting the input program current to a logic high or a logic low.
