Abstract
This invention provides a semiconductor device with high speed operation and reduced size. A circuit includes a circuit including a memory circuit and a circuit including a logic circuit; thus, the circuit functions as a memory device having a function of storing data and a function of performing logic operation. The circuit can output, in addition to data stored in the circuit, data corresponding to a result of logic operation performed using data stored in the circuit as an input signal. The circuit can directly obtain a result of logic operation from the circuit, and thus, the frequency of input/output of a signal performed between the circuit and the circuit can be reduced.
