Abstract
A semiconductor device that can perform product-sum operation with low power consumption is provided. The semiconductor device includes first and second circuits. The first circuit includes a first holding node and the second circuit includes a second holding node. The first circuit is electrically connected to first and second input wirings and first and second wirings, the second circuit is electrically connected to the first and second input wirings and the first and second wirings, and the first and second circuits have a function of holding first and second potentials corresponding to first data at the first and second holding nodes. When potentials corresponding to second data are input to the first and second input wirings, the first circuit outputs a current to one of the first wiring and the second wiring, and the second circuit outputs a current to the other of the first wiring and the second wiring. The currents output by the first and second circuits to the first wiring and the second wiring are determined in accordance with the first and second potentials held at the first and second nodes.
