  • Publication number: 20090089493
    Abstract: Operation control circuits start a first operation of any of memory cores in response to a first operation command, start a second operation of any of the memory cores in response to a second operation command, and terminate the first operation and continue the second operation in response to a termination command to terminate operations of the plurality of memory cores. For example, the semiconductor memory is mounted on a system together with a controller accessing the semiconductor memory. The termination of the operation in response to the termination command is judged in accordance with an operation state of the memory core. Accordingly, it is possible to terminate the operation of the memory core requiring the termination of operation without specifying the memory core from outside.

    Abstract: An airbag apparatus for protecting knees is provided. A breakable portion is provided in a wall of a glove compartment door for opening and closing an opening of a glove compartment. The wall faces a vehicle passenger compartment. An airbag case for housing an airbag, which is inflated by inflation fluid, is installed inside the wall. A front part of the airbag case is caused to function as a pressure receiving portion for receiving a pressure of the inflation fluid through the inflating airbag, thereby generating a reaction force advancing toward the rear side of the vehicle, so that the breakable portion is broken by the airbag inflating toward the rear side of the vehicle. The airbag is caused to protrude from the glove compartment door to the rear side of the vehicle through the breakable portion.

  • Patent number: 7471585
    Abstract: A refresh signal is output in response to a refresh request generated at predetermined cycles, and a refresh operation is performed. The refresh operation ends when a conflict occurs between an access request and the refresh request. Consequently, an access operation corresponding to the access request can be started earlier with a reduction in access time. The access time can be reduced further by changing the end time of the refresh operation in accordance with the timing of supply of the access request. Since a test circuit for notifying the state of the refresh operation to exterior is formed, the operation margin of the refresh operation can be evaluated in a short time. As a result, it is possible to reduce the development period of the semiconductor memory.
