Abstract
A small semiconductor device is provided. The semiconductor device includes a register, switches, a memory circuit, a controller, and a display. An output terminal of the register is electrically connected to two or more of the switches. The switches are electrically connected to the memory circuit. The register has a function of retaining data corresponding to a parameter used when the controller operates. The switches have a function of selecting the memory circuit to which the data retained in the register is to be output. The memory circuit has a function of retaining the data output from the register. The controller has a function of reading the data retained in the memory circuit to control operation of the display.
