  • Publication number: 20070159906
    Abstract: The present invention provides a semiconductor memory device which reduces current consumption in a standby state owing to a suitable refresh-thinning-out function, and a refresh control method thereof. When the refresh-thinning-out function is added while a refresh operation and an external access operation are being executed independently of each other, a refresh address counter outputs a refresh address Add(C) and inputs predetermined high-order bits thereof to a refresh-thinning-out control as a high-order refresh address Add(C) (m), where judgment as to whether the refresh operation is performed, is made. A refresh permission signal RFEN corresponding to the result of judgment is inputted to a word driver to activate and control the word driver. The process of judgment by the refresh-thinning-out control circuit can be embedded in an access time of a row system.

  • Patent number: 6954052
    Abstract: An electronic control apparatus includes target FR calculator that calculates a target exciting current duty ratio FR based on an exciting current inputted from FR terminal of a regulator and flowing through field coil, and information of engine operating conditions. The electronic control apparatus also includes target FR limit value FRCLP calculator that calculates a FRCLP corresponding to a drive torque limit value based on an output of a correlative information detector. A comparator compares target FR and FRCLP, outputs a control signal within FRCLP to a control unit, and controls a duty ratio FR of exciting current flowing through a field coil not to be larger than FRCLP.

  • Patent number: 6795363
    Abstract: There are provided a semiconductor memory device and a refresh control method thereof to realize a refresh operation without any problem for external accesses while realizing low current dissipation operations for executing the refresh operation in separation from external access operation, in which the refresh operation is inhibited during execution of the external accesses. During this period, the internal operation in the refresh operation is controlled for the first refresh-operation-start request, but the internal operation for the second and subsequent refresh operation start requests is inhibited. Even when a plurality of refresh-operation-start requests are outputted previously while the refresh operation is inhibited during the external access operation, only the internal operation is not executed previously and the refresh operations after completion of the external access operation can surely be executed.

  • Patent number: 6530861
    Abstract: A device for controlling an engine equipped with a synchronous mesh-type automatic transmission which decreases shock at the time of changing the speed, and improves the response and drive feeling at the time of changing the speed, including a controller that controls a throttle actuator and the automatic transmission, sets a synchronizing rotational speed of the engine rotational speed relative to the clutch when the clutch is disconnected at the time of changing the speed, fixes the throttle opening degree so that the engine rotational speed converges to the synchronizing rotational speed, gradually returns the throttle opening degree to an opening degree that corresponds to the synchronizing rotational speed when a difference between the engine rotational speed and the synchronizing rotational speed has converged to lie within a first predetermined range, and connects the clutch again when the direction of change of the engine rotational speed is inverted.
