Abstract
Semiconductor devices which are interfaced to transfer a data signal therebetween are connected to each other by a first bus which transmits the data signal at a rate at which the amplitude of the data signal needs to be adjusted. Each of the semiconductor devices has an amplitude controller for adjusting the amplitude of the data signal. A second bus connects the semiconductor devices to each other, for transmitting amplitude data for determining an amplitude of the data signal at a rate at which the amplitude does not need to be adjusted.
