Abstract
A semiconductor device with low power consumption is provided. The semiconductor device includes a first layer and a second layer. The first layer includes a first cell and a first to a third circuit, and the second layer includes a second cell and a fourth and a fifth circuit. The first, second, and fourth circuits each have a function of converting digital data into analog current. The first cell calculates a product of a value from the first current and a value from the second circuit and inputs a calculation result into a third circuit as current. The third circuit generates analog current from the input current. The second cell calculates a product of a value from the third circuit and a value from the fourth circuit and inputs a calculation result into the fifth circuit as current. The fifth circuit generates analog current from the input current.
