In an IC card, there is provided a technique capable of large expandability of a memory volume, and a memory volume and a cost matched with a user's requirement. A SIM adapter 101 has a top panel 104 for covering a recess portion. In the top panel 104, when a memory card 103 is not inserted, the top panel 104 is positioned at a first height, and, when the memory card 103 is inserted, a part of the top panel 104 is engaged with a part of the SIM adapter 101 so that the top panel is latched at a second height higher than the first height. Also, into a SIM adapter, a top panel for fixing a memory card when the memory card is inserted is inserted, and a part of the top panel is engaged with a part of the SIM adapter so that the top panel is latched when the memory card is inserted. Further, into a SIM adapter, a top panel for fixing a memory card when the memory card is inserted is inserted, and the top panel has a terminal strip contacting with both of a terminal of the SIM adapter and a terminal of the memory card so that the terminal strip electrically connects between both of them.

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.

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.

An IC card according to the present invention reduces or prevents a deterioration or damage on an electronic device to which the IC card is mounted. A buffer section made of a thermoplastic resin formed by a plastic injection molding is provided at the outer peripheral face of a memory card whose appearance is partly composed of a sealing section made of a thermosetting resin formed by a transfer molding without providing a cap. The buffer section has a taper formed at the outer peripheral corner, and further, the buffer section is softer than the sealing section and has a smooth surface. When the memory card is mounted to an electronic device, the buffer section is brought into contact with connector pins or a guide rail of a connector of the electronic device, thereby being capable of reducing or preventing the deterioration or damage on the connector.

An adapter for a memory card is disclosed which performs a change of size so that a memory card smaller in planar size but almost equal in thickness as compared with a multi-media card can be used as a multi-media card. A protuberant portion is formed behind plural external terminals formed on a back side of the adapter, whereby, while the thickness of a front side of the adapter is maintained at a standardized thickness of the multi-media card, a rear side of the adapter is made thicker than the front side and internal terminals for contact with external terminals of the memory card are disposed in the interior of the thick portion of the adapter. The versatility of an extremely small-sized memory card can be improved.

摘要:
A semiconductor chip is mounted onto a wiring substrate having external connecting terminals, electrodes on the semiconductor chip and wiring lines on the wiring substrate are connected together electrically through bonding wires, and a sealing portion is formed by resin molding, to form an IC body. Further, a case formed of a thermoplastic resin is provided. The IC body is mounted into a recess of the case through a bonding material. Thereafter, a region near the recess of the case is deformed plastically to fix the IC body to the case and then the bonding material is cured. In this way there is fabricated an IC card comprising the case and the IC body whose stability is improved by being bonded to the case through the bonding material. The production yield of the IC card can be improved.
