An object of the present invention is to provide a semiconductor device which can obtain the high potential necessary for writing data to a memory, using a small circuit area. The DCT assembly has first and second input clutches, first and second gear sets selectively connected to the engine via the respective first and second input clutches, and a transmission control module. The electronic sound generation device is also adapted to hold resultant data of arithmetic processing, which is output in synchronism with the sampling signal.
