A semiconductor device with a small circuit scale and reduced power consumption is provided. The semiconductor device includes first to fourth cells, first and second circuits, and first to fourth current generation circuits. The first cell is electrically connected to the third cell through a first wiring and the first current generation circuit, and is electrically connected to the first circuit through a second wiring. The second cell is electrically connected to the fourth cell through a third wiring and the second current generation circuit, and is electrically connected to the second circuit through a fourth wiring. The third cell is electrically connected to the second cell through the third current generation circuit and the fourth wiring. The fourth cell is electrically connected to the first cell through the fourth current generation circuit and the second wiring. The first and second current generation circuits each function as a current mirror circuit, and the third and fourth current generation circuits each function as an arithmetic circuit of a function system. The first and second cells perform an arithmetic operation of a product, and the third and fourth cells retain the result of the arithmetic operation.
