Abstract
Semiconductor devices and multiply-accumulate operation devices are disclosed. In one example, a semiconductor device includes synapses in which a nonvolatile variable resistance element taking a first resistance value and a second resistance value lower than the first resistance value and a fixed resistance element having a resistance value higher than the second resistance value are connected in series. An output line outputs a sum of currents flowing through the plurality of synapses.
