Semiconductor device including flip-flop and logic circuit

摘要

To provide a semiconductor device capable of adjusting the timing of a clock signal or a high-quality semiconductor device. The semiconductor device includes a first transistor and a circuit including a second transistor. A channel of the first transistor is formed in an oxide semiconductor layer. A first signal is input to one of a source and a drain of the first transistor. The other of the source and the drain of the first transistor is electrically connected to a gate of the second transistor. A first clock signal is input to the circuit. The circuit outputs a second clock signal. The timing of the second clock signal is different from that of the first clock signal.
