Abstract
A semiconductor device includes first through third power supply terminals respectively supplied with first, second and third power supply voltages. The semiconductor device also includes a first terminal connectable to a host device, and a second terminal connectable to a peripheral device. A first circuit block is connected to the first terminal and the first power supply terminal, and receives data output from the host device based on the first power supply voltage. A second circuit block is connected to the second terminal and the third power supply terminal, and receives data output from the peripheral device based on the third power supply voltage. A third circuit block is connected to the second power supply terminal, and controls operation of the first circuit block and the second circuit block based on the second power supply voltage.
