摘要：
A semiconductor device includes first, second and 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. The semiconductor device also includes a first circuit block connected to the first terminal and the first power supply terminal and receiving data output from the host device based on the first power supply voltage, a second circuit block connected to the second terminal and the third power supply terminal and receiving data output from the peripheral device based on the third power supply voltage, and a third circuit block connected to the second power supply terminal and controlling operation of the first circuit block and the second circuit block based on the second power supply voltage.
