US Patent 10998906 Logic device using spin torque

A logic function device according to an embodiment of the present invention includes one or more function reconfiguring units having magnetization in one direction set by spin torque caused due to an function reconfiguring current, and an output terminal formed at an end thereof; and one or more input units formed on the function reconfiguring unit and having magnetization in the one direction set by spin torque caused due to an input current, wherein an output voltage of the output terminal is determined on the basis of whether a magnetization direction of the function reconfiguring unit and a magnetization direction of the input unit are parallel or anti-parallel.
