To provide a semiconductor device in which power consumption at the time of an anti-collision operation is reduced. A semiconductor device includes an arithmetic circuit, a storage device, and circuits for transmitting and receiving signals to and from the outside. The arithmetic circuit includes a central processing unit and a controller. The central processing unit executes a program for using the controller to reduce power consumption when a signal is transmitted to the outside. The program has a structure which includes a plurality of routines. Representatively, the program includes a command determination routine, a UID value processing routine, a mask value comparison routine, an N-slot power consumption reduction routine, an N-slot counter routine, and the like. |
