1. A semiconductor device, comprising:
an output clock signal generator for receiving a first system clock signal and generating an output clock signal having a frequency n times the frequency of the first system clock signal, where n in an integer;
an output driver for synchronizing output data with the output clock signal and outputting the synchronized output data through an input and output terminal;
a restoring clock signal generator for receiving a second system clock signal and generating a plurality of restoring clock signals having the same frequency as the frequency of the second system clock signal and each having different phases; and
a high frequency equalizer for restoring lost high frequency components of input data input through the input and output terminal in response to the restoring clock signals and outputting the restored input data.
