Publication number: 20080073436Abstract: 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: November 27, 2007Publication date: March 27, 2008Inventors: Hirotaka NISHIZAWA, Akira HIGUCHI, Kenji OSAWA, Tamaki WADA, Michiaki SUGIYAMA, Junichiro OSAKO

Patent number: 7325746Abstract: 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.Type: GrantFiled: October 12, 2004Date of Patent: February 5, 2008Assignee: Renesas Technology Corp.Inventors: Hirotaka Nishizawa, Akira Higuchi, Kenji Osawa, Junichiro Osako, Tamaki Wada, Michiaki Sugiyama

Publication number: 20080025003Abstract: 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: September 28, 2007Publication date: January 31, 2008Inventors: Hirotaka Nishizawa, Kenji Osawa, Junichiro Osako, Tamaki Wada, Michiaki Sugiyama, Takashi Totsuka
