Abstract
A spin unit provided with a memory cell that stores a value of one spin of an Ising model, a memory cell that stores an interaction coefficient from an adjacent spin which interacts with the corresponding spin, a memory cell that stores an external magnetic field coefficient of the one spin and circuits that determine the next state of the one spin on the basis of a product of a value of each adjacent spin and the corresponding interaction coefficient and the external magnetic field coefficient is configured, the semiconductor device is provided with a spin array where the plural spin units are arranged and connected on a two-dimensional plane on a semiconductor substrate, a random number generator and a bit regulator, the bit regulator operates output of the random number generator and supplies a random bit to all spin units in the spin array via one wire.
