Abstract
An object of the present invention is to realize an example of configuration that approximately represents a state of quantum spin in a semiconductor device where components as a basic configuration unit are arrayed so as to search a ground state of Ising model. There is disclosed a semiconductor device provided with plural units each of which is equipped with a first memory cell that stores a value which represents one spin of the Ising model by three or more states, a second memory cell that stores an interaction coefficient showing interaction from another spin which exerts interaction on the one spin and a logical circuit that determines the next state of the one spin on the basis of a function having a value which represents a state of the other spin and the interaction coefficient as a constant or a variable.
