Patent number: 7308588Abstract: 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: GrantFiled: August 6, 2004Date of Patent: December 11, 2007Assignee: Renesas Technology Corp.Inventors: Hirotaka Nishizawa, Akira Higuchi, Kenji Osawa, Tamaki Wada, Michiaki Sugiyama, Junichiro Osako

Publication number: 20070262239Abstract: When light is made incident into antenna layers 11a, 11b, and 11c of a photodetector 1, specific wavelength components of light contained in the incident light combine with surface plasmons of the antenna layers 11a, 11b, and 11c, and surface plasmon resonance occurs. Thereby, near-field lights are outputted from through-holes 13 of the antenna layers 11a, 11b, and 11c. The near-field light outputted from each through-hole 13 reaches a light absorbing layer 4 via light receiving surfaces 4a, 4b, and 4c. The light absorbing layer 4 generates a charge of an amount according to the amount of received light. Since cycle intervals ?a, ?b, and ?c of convex portions 12 in the antenna layers 11a, 11b, and 11c are different from each other, the wavelength component of light that combines with a surface plasmon differs in each of the antenna layers 11a, 11b, and 11c. Consequently, a plurality of wavelength components of light can be detected.Type: ApplicationFiled: May 9, 2007Publication date: November 15, 2007Inventors: Minoru Niigaki, Toru Hirohata, Hiroyasu Fujiwara, Akira Higuchi

Publication number: 20070150633Abstract: 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: March 1, 2007Publication date: June 28, 2007Inventors: Akira HIGUCHI, Hirotaka Nishizawa, Junichiro Osako, Kenji Osawa

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
