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: 7341198Abstract: An IC card 1CD includes a frame member portion 1CB1, and an IC card main body 15 held in a state of being hung by a connecting portion 1CB2 in a frame thereof. The IC card main body 15 is made to constitute a card type information medium having a high functional performance having both of a function as a so-to-speak IC card and a function as a so-to-speak memory card having a capacity larger than that of the IC card and a function higher than that of the IC card capable of executing a security processing. An outer shape of the IC card main body 15 is formed in compliance with RS-MMC outer shape standard. A surface of a cap portion 1CB3 of the IC card main body 15 is printed with a desired character, pattern, diagram and photograph or the like by a printing method used in steps of fabricating a general IC card, and the IC card 15 is provided with higher acknowledgement performance, security performance and outlook.Type: GrantFiled: February 20, 2004Date of Patent: March 11, 2008Assignee: Renesas Technology Corp.Inventors: Hirotaka Nishizawa, Junichiro Osako, Kenji Osawa, Tamaki Wada, Michiaki Sugiyama

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

Patent number: 7322531Abstract: A memory card wherein a substrate is affixed to a cap is formed without the projection of substrate edges from a back surface of the cap. The memory card includes a substrate having a sealing member bonded to a recess in the cap. By utilizing a difference in thermal expansion coefficient between the sealing member and the substrate, the substrate is warped so that its central portion projects away from the cap. The shallow recess is deeper than the sum of the thickness of the substrate and the thickness of an adhesive for bonding the substrate to the bottom of the shallow recess, whereby peripheral edges of the substrate retract into the shallow recess without projecting from the back surface of the cap. The cap is shaped as a card several millimeters thick. A memory chip and control chip are incorporated in the sealing member.Type: GrantFiled: January 6, 2006Date of Patent: January 29, 2008Assignees: Hitachi ULSI Systems Co., Ltd., Renesas Technology CorporationInventors: Takahiro Osawa, Yoichi Kawata, Atsushi Fujishima, Tamaki Wada, Kenichi Imura

Patent number: 7296754Abstract: An IC card module includes first external connecting terminals and 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). 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. The first and second external connecting terminals include signal terminals electrically separated from one another.Type: GrantFiled: May 10, 2005Date of Patent: November 20, 2007Assignee: Renesas Technology Corp.Inventors: Hirotaka Nishizawa, Takashi Totsuka, Kenji Osawa, Junichiro Osako, Tamaki Wada, Michiaki Sugiyama
