Patent number: 8018038Abstract: An IC card capable of reinforcing the prevention of the electrostatic damage without causing a rise in the cost of a semiconductor integrated circuit chip. The semiconductor integrated circuit chip (2) is mounted on a card substrate (1), and plural connection terminals (3) are exposed. The connection terminals are connected to predetermined external terminals (4) of the semiconductor integrated circuit chip, first overvoltage protection elements (7, 8, 9) connected to the external terminals are integrated in the semiconductor integrated circuit chip, and second overvoltage protection elements such as surface-mount type varistors (11) connected to the connection terminals are mounted on the card substrate. The varistors are variable resistor elements having a current tolerating ability greater than that of the first overvoltage protection elements.Type: GrantFiled: July 14, 2010Date of Patent: September 13, 2011Assignee: Renesas Electronics CorporationInventors: Hirotaka Nishizawa, Yosuke Yukawa, Takashi Totsuka

Publication number: 20090181721Abstract: A multifunction IC card (MFC) has compatibility with a multimedia card, an SD card, etc. in that connector terminals (#1 through #13) are disposed on a card substrate (1) in two rows in a zigzag fashion, and realizes multifunction facilities in that a memory card unit (3) and an SIM (Subscriber Identity Module) card unit (4) are respectively connected and mounted to predetermined terminals of the connector terminals (#1 through #13). The memory card unit (3) and the SIM card unit (4) are respectively separately provided with areas for storing secret codes for security. Thus, one IC card is capable of implementing multifunction facilities different in security level. Owing to the adoption of a plural-column layout corresponding to a form typified by the zigzag fashion in an array of the connector terminals, a relatively simple structure can be adopted in a card slot.Type: ApplicationFiled: March 23, 2009Publication date: July 16, 2009Inventors: Hirotaka NISHIZAWA, Haruji ISHIHARA, Atsushi SHIRAISHI, Yosuke YUKAWA
