Patent number: 8897736Abstract: A mobile communication terminal device whose authentication and settlement functions by noncontact proximity communication can be continuously used even after operating voltage from battery power drops is provided. Only when the supply of required power from a battery is lost, a security controller is controlled into a mode in which it operates with low power consumption and noncontact authentication and settlement functions are ensured by external electromagnetic field power. Specifically, the following is implemented: when there is the supply of required power from the battery, it is made possible to carry out high-performance, multifunctional authentication and settlement processing making good use of high-speed processing, mass storage, and the like which are the advantages of the security controller essentially driven by battery; and in an anomalous instance in which the battery remaining capacity is lost, it is made possible to carry out minimal authentication and settlement processing.Type: GrantFiled: June 19, 2013Date of Patent: November 25, 2014Assignee: Renesas Electronics CorporationInventors: Shigemasa Shiota, Kunihiro Katayama, Shinichi Fukasawa, Takeo Kon, Seiji Kobayashi

Only when the supply of required power from a battery is lost, a security controller is controlled into a mode in which it operates with low power consumption and noncontact authentication and settlement functions are ensured by external electromagnetic field power. Thus the noncontact authentication and settlement functions can be used even after the battery remaining capacity is lost by use of a communication function for the principal purpose.Type: GrantFiled: July 18, 2010Date of Patent: July 2, 2013Assignee: Renesas Electronics CorporationInventors: Shigemasa Shiota, Kunihiro Katayama, Shinichi Fukasawa, Takeo Kon, Seiji Kobayashi

Patent number: 7652363Abstract: Wiring lines for the supply of a voltage to feed a drive voltage to an integrated circuit formed in a semiconductor chip are disposed so as to cover a main surface of the semiconductor chip, so that, if the wiring lines are removed for the purpose of analyzing information stored in the semiconductor chip, the integrated circuit does not operate and it is impossible to analyze the information. Further, there is provided a processing detector circuit for detecting that the wiring lines have been tampered with. When the processing detector circuit detects a change in the state of the wiring lines, the integrated circuit is reset. Thus, it is possible to improve the security of information stored on the card.Type: GrantFiled: May 24, 2006Date of Patent: January 26, 2010Assignee: Renesas Technology Corp.Inventors: Hirotaka Mizuno, Yoshio Masumura, Takeo Kon, Yukio Kawashima

Publication number: 20090144834Abstract: A data processing circuit includes a rewritable nonvolatile memory and a controller performing nonvolatile memory control and external interface control. A first detector and a second detector are employed to detect respectively whether the operation of the data processing circuit deviates from a first operating condition and a second operating condition, wherein the second operating condition is severer than the first operating condition. When the first detector detects deviation from the first operating condition, reset is instructed to the controller. When the second detector detects deviation from the second operating condition, the controller backs up an internal state and imposes a restriction on external access to a storage region of the nonvolatile memory.Type: ApplicationFiled: November 14, 2008Publication date: June 4, 2009Inventors: Yoshinori MOCHIZUKI, Masaharu Ukeda, Shigemasa Shiota, Takeo Kon

Patent number: 6757201Abstract: The invention facilitates to meet both of the mode of use that finds precedence in frequent rewrite to the nonvolatile memory and data retention during the power supply being cut off, and the mode of use that finds precedence in the data retention characteristic. The controller enables an information storage operation to the nonvolatile memory cells, by means of erase and write processing through boosting of the voltage applied to the nonvolatile memory cells and clamping of the boosted voltage, and performs a selection control that selects the application interval of the boosted voltage applied during the information storage operation and so forth. This selection control enables utilizing the nonvolatile memory cells as temporary rewrite areas, and facilitates to meet both of the mode of use that finds precedence in data retention during the power supply being cut off, and the mode of use that finds precedence in the data retention characteristic.Type: GrantFiled: January 22, 2003Date of Patent: June 29, 2004Assignees: Renesas Technology Corporation, Hitachi ULSI Systems Co., Ltd.Inventors: Yuki Matsuda, Kenya Otani, Minoru Kato, Takeo Kon
