  • Publication number: 20110182109
    Abstract: A variable resistance nonvolatile memory device (100) according to an aspect of the present invention includes: a plurality of memory cells (M11, M12, M21, M22) in each of which a variable resistance element (R11, R12, R21, R22) and a current steering element (D11, D12, D21, D22) having two terminals are connected in series; a current limit circuit (105b) which limits a first current flowing in a direction for changing the memory cells (M11, M12, M21, M22) to a low resistance state; and a boost circuit (105d) which increases, when one of the memory cells (M11, M12, M21, M22) changes to the low resistance state, the first current in a first period before the memory cell changes to the low resistance state.

  • Publication number: 20110118933
    Abstract: After a request for first data is received from a first diagnostic unit, when a request for second data is received from a second diagnostic unit, if the first data and the second data of the same type, then a communication unit requests the electronic control unit to send the same type of data, and sends the same type of data received from the electronic control unit to the first diagnostic unit and the second diagnostic unit. If the first data and the second data are of different types, then the communication unit requests the electronic control unit to send the first data and the second data, receives the first data and the second data all together from the electronic control unit, sends the received first data to the first diagnostic unit, and sends the received second data to the second diagnostic unit.

  • Patent number: 7375958
    Abstract: A plurality of specific external connecting parts can be short-circuited, without increasing the number of parts and mounting work. A plurality of external connecting parts provided in parallel to each other, and a short-circuit part for short-circuiting edges located at rear end side of each of a first external connecting part and a second external connecting part which separate external connecting parts not short-circuited among the external connecting parts are inserted therebetween are comprised. The short-circuit part is formed by upward or downward bending process, and has a curved part.

  • Patent number: 7239572
    Abstract: This multiport memory has a memory hold circuit, a plurality of write circuits and read circuits, and a read/write capability regulating circuit. The read/write capability regulating circuit individually sets a write/read capability of each of the write/read circuits. The read/write capability regulating circuit determines, using an operating state determining circuit, the number of writing/reading times per unit time in accordance with an operating state of each of the read/write circuits. As the operating state determining circuit used is a noise amount detection circuit, an operation completion detecting circuit, or a potential fluctuation detecting circuit.

  • Patent number: 6979227
    Abstract: According to the present invention, there is provided a card adapter which is capable of preventing contact failure between a cover member and a ground terminal caused by the floating of the cover member when a card is inserted into a card inserting portion. A contacting surface 40 facing a back-end surface 1b of the card inserting portion 1a is provided on the ground terminal 12. A ground contacting portion 41 comprising a contacting portion 41a brought into contact with the contacting surface 40, a plate spring portion 41b extending in a widthwise direction of the card inserting portion 1a and bent in a lengthwise direction of the card inserting portion 1a, and a cantilever supporting portion 41c for supporting the plate spring portion 41b in a cantilever manner is formed in a bent portion 4a provided in a front-end portion of the cover member 4.
