  • Patent number: 7088636
    Abstract: The present invention provides a semiconductor memory circuit capable of reducing current consumption at non-operation in a system equipped with a plurality of chips that share the use of a power supply, address signals and a data bus. The semiconductor memory circuit has an internal circuit which is capable of selectively performing the supply and stop of an operating voltage via switch means and includes a memory array. An input circuit, which receives a predetermined control signal therein, controls the supply and stop of the operating voltage by the switch means to reduce a DC current and a leak current when no memory operation is done, whereby low power consumption can be realized.

  • Publication number: 20060163973
    Abstract: A plurality of lead-out wires 10 and 11 provided with insulating coating are stacked in a pressure sensitive sensor 1 and are molded in the shape of a cable, and at a distal end portion S the lead-out wire 11 is connected to a central electrode 2 and the lead-out wire 10 to an outer electrode 4. Consequently, if the pressure sensitive sensor 1 is connected to an external circuit 12, and a third resistor 15 is connected between the lead-out wire 10 and the lead-out wire 11 in the external circuit 12, a circuit is formed which is equivalent to a circuit for detecting a disconnection and a short circuit in a conventional pressure sensitive sensor, making it possible detect a disconnection and a short circuit of each electrode. Further, the construction of the leading end portion becomes simple, and a nonsensitive area can also be reduced, so that the detection performance improves.
