Abstract

[Problem] To provide a semiconductor device that can perform sum-of-accumulate operations with low power consumption. [Solution] An arithmetic circuit having circuits MC and MCr, wherein circuit MC has a holding node nd1, and circuit MCr has a holding node nd1r. Circuits MC and MCr are electrically connected to input wirings X1L and X2L and wirings OL and OLB, respectively, and each of circuits MC and MCr holds first and second potentials corresponding to first data in its respective holding node. When a potential corresponding to second data is input to input wirings X1L and X2L, circuit MC outputs a current to either wiring OL or wiring OLB, and circuit MCr outputs a current to the other of wiring OL or wiring OLB. The current that circuits MC and MCr output to wiring OL or wiring OLB is determined according to the first and second potentials held in the holding nodes nd1 and nd1r. [Selection Diagram] Figure 9

Currently, there is a great deal of activity in developing integrated circuits that mimic the structure of the human brain. These integrated circuits incorporate the brain's structure as electronic circuits, possessing circuits that correspond to the "neurons" and "synapses" of the human brain. For this reason, such integrated circuits are sometimes called "neuromorphic,""brainmorphic," or "brain-inspired." These integrated circuits have a non-von Neumann architecture and are expected to be able to perform parallel processing with extremely low power consumption compared to von Neumann architectures, where power consumption increases with increasing processing speed. A model of information processing that mimics a neural network having "neurons" and "synapses" is called an artificial neural network (ANN). For example, Non-Patent Documents 1 and 2 disclose a computing device that constructs an artificial neural network using SRAM (Static Random Access Memory). M.
