Abstract: A random number generator using a stochastic magnetic tunneling junction structure is proposed. The random number generator includes: a first magnetic tunneling junction structure including a first pinned layer, a first tunnel junction layer, and a first free layer that are sequentially stacked, and stochastically having a parallel state and an anti-parallel state in which a magnetization direction of the first pinned layer and a magnetization direction of the first free layer is parallel and anti-parallel, respectively; and a first power supplier connected to the first magnetic tunneling junction structure and configured to supply AC voltage/current to the first magnetic tunneling junction structure.

Abstract: 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.
