  • Publication number: 20080149739
    Abstract: A semiconductor device includes external interface terminals and processing circuits, and it is fed with an operating power source when detachably set in a host equipment. Power source feeding terminals (VCC, VSS) among the external interface terminals are long enough to keep touching the corresponding terminals of the host equipment for, at least, a predetermined time period since the separation of an extraction detecting terminal among the external interface terminals, from the corresponding terminal of the host equipment, and they are formed to be longer in the extraction direction of the semiconductor device than the extraction detecting terminal. These power source feeding terminals are a power source terminal and a ground terminal, and any power source compensating capacitor is not connected between the power source terminal and the ground terminal.

  • Publication number: 20080073436
    Abstract: 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.

  • Patent number: 7325746
    Abstract: 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.

  • Patent number: 7303138
    Abstract: An IC card has a card substrate having semiconductor integrated circuit chips mounted thereon and a plurality of connector terminals formed thereon. The connector terminals are exposed from a casing. The connector terminals are laid out in plural sequences in staggered form between sequences adjacent to one another forward and backward as viewed in an IC card inserting direction. Owing to the adoption of the staggered layout, a structure or configuration wherein the amounts of protrusions of socket terminals of a card socket are changed and the socket terminals are laid out in tandem, can be adopted with relative ease. If a connector terminal arrangement of a downward or low-order IC card is adopted as a specific connector terminal sequence as it is, whereas a function dedicated for an upward or high-order IC card is assigned to another staggered connector terminal arrangement, then backward compatibility can also be implemented with ease.
