ABSTRACT:
A semiconductor device includes a transmitting unit for receiving plural bits of data to modulate the data to a 1-bit pulse signal whose pulse width corresponds to a value of the data and transferring the pulse signal to a transfer line; and a receiving unit for receiving the pulse signal transferred through the transfer line to demodulate the pulse signal to the plural bits of data.
