Abstract
A semiconductor device with a novel structure is provided. The semiconductor device includes a digital calculator, an analog calculator, a first memory circuit, and a second memory circuit. The analog calculator, the first memory circuit, and the second memory circuit each include a transistor including an oxide semiconductor in a channel formation region. The first memory circuit has a function of supplying first weight data to the digital calculator as digital data. The digital calculator has a function of performing product-sum operation using the first weight data. The second memory circuit has a function of supplying second weight data to the analog calculator as analog data. The analog calculator has a function of performing product-sum operation using the second weight data. The amount of current flowing between a source and a drain of at least one of the transistors each including the oxide semiconductor in the channel formation region in the analog calculator and the second memory circuit is the amount of current flowing when the transistor operates in a subthreshold region.
