Abstract
A semiconductor device with reduced power consumption is provided. The semiconductor device includes a transmitter unit, a receiver unit, a bias-outputting unit, and a controller unit. The bias-outputting unit has a plurality of memory units. The plurality of memory units each retains information to determine transmission power. The receiver unit receives a request signal transmitted from a base station and supplies it to the controller unit. The controller unit selects one of the plurality of memory units according to the request signal. The memory unit has an OS transistor and retains information when power supply is stopped.
