Semiconductor device and electronic device

Abstract

A semiconductor device with a small circuit scale and reduced power consumption is provided. The semiconductor device includes first to fifth circuits. Each of the first to fourth circuits includes first and second cells, a sixth circuit, first and second current generation circuits, a first input terminal, and a second output terminal. The first circuit to the fourth circuit are electrically connected to each other in a ring, and the first circuit is electrically connected to the fifth circuit. In each of the first to fourth circuits, the first cell is electrically connected to the second cell through the first wiring, the first current generation circuit, and the third wiring, and is electrically connected to the first input terminal and the sixth circuit through the second wiring. The second cell is electrically connected to the first output terminal through the second current generation circuit. Note that the first current generation circuit functions as a current mirror circuit, and the second current generation circuit functions as an arithmetic circuit of a function system. The first cell performs an arithmetic operation of a product, and the second cell retains the result of the arithmetic operation.
