Abstract
An interface circuit includes a selection circuit receiving first and second signals, generating a time division serial signal by selecting one of the first and second signals in response to the voltage level of a clock signal provided from the outside of a semiconductor device, and outputting the time division serial signal to a single input terminal of the semiconductor device via a single signal line, a first holding circuit, which is connected to the terminal for receiving the time division serial signal, for capturing and outputting the first signal of the time division serial signal in response to the rise of the clock signal, and a second holding circuit, which is connected to the terminal for receiving the time division serial signal, for capturing and outputting the second signal of the time division serial signal in response to the fall of the clock signal.
