Publication number: 20060087016Abstract: 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.Type: ApplicationFiled: October 18, 2005Publication date: April 27, 2006Inventors: Tamaki Wada, Hirotaka Nishizawa, Michiaki Sugiyama, Junichiro Osako

Publication number: 20050253239Abstract: This invention is to provide an ultra-miniaturized, thin-sized memory card provided with a mechanism for preventing a wrong insertion to a memory card slot. A multi-function memory card is composed of a card body and a cap for housing the card body. The card body is made of mold resin that encapsulates plural semiconductor chips mounted on a main surface of a wiring substrate. The card body is housed into the cap with the back face of the wiring substrate facing outward. Guide channels are provided at both side faces of the cap for preventing that the card is inserted upside down. Further, a convex section is provided at the trailing edge of the cap for preventing that the card is inserted in the wrong direction.Type: ApplicationFiled: April 25, 2005Publication date: November 17, 2005Inventors: Hirotaka Nishizawa, Kenji Osawa, Junichiro Osako, Tamaki Wada, Michiaki Sugiyama, Takashi Totsuka

An IC card module includes a plurality of first external connecting terminals and a plurality of second external connecting terminals both exposed to one surface of a card substrate, a microcomputer connected to the first external connecting terminals, a memory controller connected to the second external connecting terminals, and a volatile memory connected to the memory controller. The shape of the card substrate and the layout of the first external connecting terminals are based on a standard of plug-in UICC of ETSI TS 102 221 V4.4.0 (2001-10) or have compatibility. The second external connecting terminals are disposed outside the minimum range of the terminal layout based on the standard for the first external connecting terminals.Type: ApplicationFiled: May 10, 2005Publication date: November 17, 2005Inventors: Hirotaka Nishizawa, Takashi Totsuka, Kenji Osawa, Junichiro Osako, Tamaki Wada, Michiaki Sugiyama

Publication number: 20050094463Abstract: An antenna connection function for a noncontact interface is provided by suppressing a modification in a pin arrangement and a pin shape of a memory card that does not correspond to the noncontact interface. Two antenna connecting pins having the memory card are divided into two areas in which a size of one potential supply pin is the largest and used as a split pin arranged at intervals. Because a size of the two antenna connecting pins is at maximum as large as the size of the potential supply pin, the two antenna connecting pins are provided and the memory card that corresponds to the noncontact interface is obtained by devoting a pin area having the size of the one potential supply pin to the memory card that does not correspond to the noncontact interface. Accordingly, the pin area of the memory card that corresponds to the noncontact interface can be formed without departing from the pin area of the memory card that does not correspond to the noncontact interface.Type: ApplicationFiled: October 12, 2004Publication date: May 5, 2005Inventors: Hirotaka Nishizawa, Akira Higuchi, Kenji Osawa, Junichiro Osako, Tamaki Wada, Michiaki Sugiyama

Publication number: 20050082375Abstract: An IC card is prevented from falling off readily an electronic device while maintaining the mechanical strength of the IC card. A recess for preventing a memory card from falling off an electronic device is provided at the side of one side of a principal surface of a cap of the memory card which is configured by fitting a memory body in a recess formed on a parts mounting surface of the cap. The bottom of the recess is terminated in the middle of the thickness of the cap. This construction makes it possible to prevent the memory card from falling off readily an electronic device while maintaining the mechanical strength of the memory card.Type: ApplicationFiled: October 12, 2004Publication date: April 21, 2005Inventors: Hirotaka Nishizawa, Akira Higuchi, Kenji Osawa, Junichiro Osako, Tamaki Wada

Publication number: 20050052924Abstract: The present invention provides a memory card equipped with an interface controller connected to external connecting terminals, a memory connected to the interface controller, and a security controller connected to the interface controller. A second external connecting terminal capable of supplying an operating power supply to the security controller is provided aside from a first external connecting terminal which supplies an operating power supply to the interface controller and the memory. An interface unit of the interface controller connected to the security controller receives the operating power supply from the second external connecting terminal and thereby enables a stop of the supply of the operating power supply from the first external connecting terminal. Even if the supply of the operating power supply to the interface controller is cut off, the output of the interface unit is not brought to an indefinite state.Type: ApplicationFiled: August 6, 2004Publication date: March 10, 2005Inventors: Hirotaka Nishizawa, Akira Higuchi, Kenji Osawa, Tamaki Wada, Michiaki Sugiyama, Junichiro Osako

Publication number: 20040070952Abstract: 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.Type: ApplicationFiled: October 2, 2003Publication date: April 15, 2004Applicants: Renesas Technology Corp., Hitachi ULSI Systems Co., Ltd.Inventors: Akira Higuchi, Hirotaka Nishizawa, Junichiro Osako, Kenji Osawa

Publication number: 20040062112Abstract: The productivity of an IC card is to be improved. In a memory card of the type in which a memory body having a wiring substrate and a semiconductor chip mounted on a main surface of the wiring substrate is held so as to be sandwiched in between a first case and a second case, a planar outline of the memory body is smaller than half of a planar outline of the memory card. The memory body is disposed so as to be positioned closer to a first end side as one short side of the memory card with respect to a midline between the first end side and a second end side as an opposite short side of the memory card positioned on the side opposite to the first end side. The other area than the memory body-disposed area in the first and the second case is used as another functional area.Type: ApplicationFiled: September 24, 2003Publication date: April 1, 2004Applicants: Renesas Technology Corp., Hitachi ULSI Systems Co., Ltd.Inventors: Hirotaka Nishizawa, Kenji Osawa, Akira Higuchi, Junichiro Osako, Tamaki Wada
