ABSTRACT:
A card device has a regulator (5), a first internal circuit (6) and a second internal circuit (7), and the regulator supplies, to the second internal circuit, an internal voltage generated by dropping an external voltage (VCC) when the external voltage is high, and exactly supplies the external voltage as the internal voltage to the second internal circuit when the external voltage is low, and the external voltage is supplied as an operating power source to the first internal circuit and a transition to a low consumed power state is carried out if a command is not input for a certain period. The card device stops the operation of the regulator and suppresses the supply of the internal voltage to the second internal circuit in the transition to the low consumed power state. In the low consumed power state, consequently, it is possible to suppress a power consumption in each of the regulator and the second internal circuit in the card device.
