Abstract

A DC--DC converter using a planar inductor is arranged in an IC memory card incorporating an EEPROM memory chip, and power supply is performed such that a voltage is adjusted by a dropping regulator, thereby reducing power consumption. The power consumption of the IC memory card incorporating the EEPROM can be reduced. The IC card can be driven by a single power supply, thereby providing a compact portable information device which can be driven by a battery for a long time.
