Abstract:
A processing unit carries out a predetermined data processing on the data in a storage unit. The storage unit is connected to the processing unit with a plurality of connecting lines. A voltage generating unit is connected to each of the connecting lines via a corresponding termination resistor and that generates a termination voltage to be applied to the connecting lines. An interrupting unit is connected between the connecting lines and the termination resistors, and it applies or does not apply the termination voltage to the connecting lines depending on a data processing state of the processing unit.
