<p>A driver circuit (10) comprising driver means (30) and driver control means (20) for controlling a driver by comparing the present data and the past data on an input signal. The driver means (30) includes a plurality of parallel drivers, and the driver control means (20) compares the present data on the input signal and the data one cycle before and drivers the plural parallel drivers, if different, to augment the driving abilities of the drivers. The driver control means (20) further compares the present data and the data two cycles before and does not drives part of the parallel drivers, if identical, so that the rate of the augmentation of the driving abilities can be lowered.</p> |
