Semiconductor device for calculating an interaction model

Abstract

A semiconductor device includes a spin array in which a plurality of memory cells are disposed in a matrix configuration, a group of a predetermined number of memory cells is collected in units of spin units, and a plurality of the spin units are disposed with an adjacency; a word line provided in correspondence with rows of the memory cells; a bit line pair provided in correspondence with columns of the memory cells; a multiword decoder configured to multiplex a word address according to an input of a multiplicity specify signal to a word line and simultaneously activate a plurality of word lines; and a bit line driver configured to subject a plurality of memory cells, of the memory cells connected to bit line pairs and arrayed in a column direction, activated by the plurality of the word lines to a write operation or a read operation.
