Abstract
A semiconductor device capable of convolutional processing with low power consumption is provided. In the semiconductor device, a first circuit includes a first holding portion and a first transistor, and a second circuit includes a second holding portion and a second transistor. The first and second circuits are electrically connected to first and second input wirings and first and second wirings. The first holding portion has a function of holding a first current flowing through the first transistor, and the second holding portion has a function of holding a second current flowing through the second transistor. The first and second currents are determined by a filter value used for convolutional processing. When a potential corresponding to image data subjected to convolutional processing is 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 amount of current output from the first and second circuits to the first wiring or the second wiring is determined by the filter value and the image data.
