Semiconductor device

To provide a semiconductor device which can perform initialization to a first state of two states of the first state and a second state, and which can generate a signal having a potential corresponding to the initialized first state. The present invention is the semiconductor device which can perform initialization to "0" (a first state) of two states of "0" and "1" (a second state), and which can generate a signal having a potential corresponding to initialized "0". The semiconductor device 10 includes a plurality of flip-flop circuits 2 that are connected in parallel and which can hold the two states of "0" and "1"; and an AND circuit 3 which generates and outputs a signal having a potential corresponding to "0" when a state held in at least one flip-flop circuit 2 among the flip-flop circuits 2 is "0". The AND circuit is connected to the flip-flop circuits 2.
