摘要:
The present invention realizes a card on which a secure IC chip (a first semiconductor chip) that operates on both of a high power source voltage and a low power source voltage, and a nonvolatile semiconductor storage chip that operates on the lower power source voltage are mounted. Means for operating the card without exerting an adverse influence of the nonvolatile semiconductor storage chip when the high power source voltage is supplied is realized. A card has a voltage supply interrupting unit which is coupled to a power source terminal to which a first power source voltage and a second power source voltage higher than the first power source voltage are supplied, and a grounding terminal to which a grounding voltage is supplied. The voltage supply interrupting unit, when the first power source voltage is supplied, supplies voltage to a nonvolatile semiconductor storage chip and, when the second power source voltage is supplied, stops supplying the voltage to the nonvolatile semiconductor storage chip.

A semiconductor device has operation modes selectable through the control by a second microcomputer (113). In a first mode, an operation of a memory controller (105) responding to a memory card command from a memory card interface terminal and an operation of a first microcomputer (106) responding to an IC card command from an IC card interface terminal are separately performed. In a second mode, the first microcomputer operates in response to the IC card command from the IC card interface terminal. In a third mode, the memory controller and the first microcomputer operate in response to an undefined IC card command from the IC card interface terminal. In a fourth mode, the memory controller and the first microcomputer operate in response to the memory card command from the memory card interface terminal. Convenience of the semiconductor device having an IC card function and a memory card function is improved.

The loss of data stored in a secure memory card, such as a SIM card, due to the physical destruction thereof is prevented. A host unit performs card authentication of a memory card, and transmits update data for the memory card by security communication to update data when the result of the authentication is OK. Then, the host unit outputs a request for mirror-updating the card data to a base station server. When an access is permitted, the card data is transmitted to the base station server via the host unit to mirror-update the card data. When the mirror-updating of the card data is completed, the base station server returns a completion confirmation to the host unit, so that a data backup process is completed. By thus causing the base station server to mirror-update the data in the memory card, the loss of the stored data is prevented.

A semiconductor device improved in IC card function is disclosed. An external connecting terminal for extended interface not conforming to ISO/IEC7816-3 is disposed on a first main surface of a card chip and in an area sandwiched in between two rows of external connecting terminals for interface conforming to ISO/IEC7816-3 which is for IC card function. With this layout, the memory card function and other electronic circuit functions can be incorporated into the card chip and hence it is possible to improve the function of the card chip.

An IC card and card adapters are designed so that the IC card of a specific standard (e.g., MMC standard) is compatible with IC cards and terminals of other standards (e.g., MS card standard and USB terminal standard). In the IC card (MMC), a controller IC, which is connected to a flash memory, includes a voltage pull-down detector, a mode controller, a USB-mode interface controller, a MS-mode interface controller, and an MMC/SD-mode interface controller. The card adapters suffice to have component parts which are easy in formation and low in cost such as wiring lines and resistors. The voltage pull-down detector of the IC card detects the voltage pull-down caused by the resistors, and the mode controller selects the USB-mode interface controller, MS-mode interface controller or MMC/SD-mode interface controller so that the IC card becomes compatible with the corresponding IC card standard.

On an adapter mounting portion 3a having a projecting cross section which is formed on a cap 3 of a small-sized memory card 1, a recessed portion of an adapter 2 side is fitted so that both parts are formed as an integral unit in a replaceable manner. Accordingly, the small-sized memory card 1 can maintain the dimensional compatibility with respect to existing memory cards whereby the small-sized memory card 1 can be used also in equipment which is designed to cope with the existing memory cards.
摘要:
A multifunction IC card (MFC) has compatibility with a multimedia card, an SD card, etc. in that connector terminals (#1 through #13) are disposed on a card substrate (1) in two rows in a zigzag fashion, and realizes multifunction facilities in that a memory card unit (3) and an SIM (Subscriber Identity Module) card unit (4) are respectively exclusively connected and mounted to predetermined terminals of the connector terminals (#1 through #13). The memory card unit (3) and the SIM card unit (4) are respectively separately provided with areas for storing secrete codes for security. Thus, one IC card is capable of implementing multifunction facilities different in security level. Owing to the adoption of a plural-column layout corresponding to a form typified by the zigzag fashion in an array of the connector terminals, a relatively simple structure can be adopted in a card slot, wherein the amounts of protrusion of slot terminals in a card slot are alternately changed in association with a zigzag section, and the slot terminals are disposed in a row in parallel as a whole.
