Abstract
A semiconductor device with a high driving speed is provided. The semiconductor device includes first to fourth cells, a converter circuit, and first to fourth wirings. The first and second cells make a first current and a second current each corresponding to the product of first data and second data flow in the first wiring and the second wiring, respectively. The third and fourth cells make base currents in the same amount flow in the first and second wirings. The converter circuit outputs, from an output terminal thereof, a voltage corresponding to the differential current between the sum of the first current and the base current flowing in the first wiring and the sum of the second current and the base current flowing in the second wiring.
