When an IC card is passed over an external card reading and writing apparatus, the IC card starts communication with the card reading and writing apparatus via a wireless interface, so that a change in the internal state of the IC card is reported to an external device via an external wired interface or a dedicated control signal line, thus allowing a specific application to be enabled on the external device or allowing a controller to be powered on and activated. Alternatively, the controller is powered off and deactivated. Accordingly, processing according to the communication state between the IC card and the card reading and writing apparatus or the internal state of the IC card can be smoothly initiated.

IC chip and information processing terminal

A memory region on an IC card has a hierarchical structure. Each application allocated on the memory region is registered in a directory, and the memory region is managed in directory units. A personal identification code is set for each application and directory, and the access right is controlled in application units or directory units. If a mobile terminal is lost, the right to access each application in the IC card automatically disappears. Therefore, the right to access each application allocated to the memory region on the IC card is efficiently controlled.

Integrated circuit device, information processing apparatus, memory management method for information storage device, mobile terminal apparatus, semiconductor integrated circuit device, and communication method using mobile terminal apparatus

An application program relating to a process of an integrated circuit is stored in a virtual integrated circuit storage area server apparatus. Following a mutual authentication between the IC and the virtual storage area server apparatus through a portable communication function unit, the server apparatus executes the application program. Additionally, through the IC, the portable communication function unit, a wireless communication line, and a network, communicate with an IC_R/W apparatus and perform a process relating to a service in collaboration with each other.

Service providing method and integrated circuit

A semiconductor integrated-circuit device rectifies a received carrier wave, generates a first power-supply voltage based on the rectified output, and selects, as a power-supply voltage required for operation, one of the first power-supply voltage and a supplied second power-supply voltage. The first power-supply voltage is selected as the power-supply voltage required for operation when the second power-supply voltage is lower than a threshold value. The second power-supply voltage is selected as the power-supply voltage required for operation when the second power-supply voltage is equal to or higher than the threshold value and an instruction to operate in accordance with a predetermined function is given.

Chip for non-contact reader/writer having power-supply management function

The present invention relates to a semiconductor integrated-circuit device capable of seamlessly switching a power source obtained by rectifying a carrier wave and an external power source. The semiconductor integrated-circuit device having a non-contact card function and a non-contact reader/writer function includes a rectifierfor rectifying a received carrier wave, a serial regulatorfor obtaining a predetermined voltage from an output voltage of the rectifierand a power-supply control circuitfor turning on/off the voltage from a batteryIn a case where the output voltage of the batteryis equal to or higher than a predetermined voltage, the power-supply control circuitselects the voltage of the batteryas power required for operation of an ICwhen a reader/writer mode signal or a card mode signal is received. On the other hand, when the output voltage of the batteryis lower than the predetermined voltage, the power-supply control circuitselects the output voltage from the rectifieras power required for operation of the ICThe present invention can be applied to a portable terminal, such as a cellular phone.
