US 2016/0062951 A1 · SEMICONDUCTOR DEVICE

Abstract

A semiconductor device includes a plurality of spin units individually including a memory cell configured to store values of spins in an Ising model, a memory cell configured to store an interaction coefficient from an adjacent spin that exerts an interaction on the spin, a memory cell configured to store an external magnetic field coefficient of the spin, and an interaction circuit configured to determine a subsequent state of the spin. The spin units individually include a random number generator configured to supply the random number to the plurality of the spin units and generate two-valued simulated coefficients of two values or simulated coefficients of three values in performing an interaction to determine a subsequent state of a spin of the spin units from a value of a spin from an adjacent spin unit, an interaction coefficient, and an external magnetic field coefficient.
