  • Patent number: 11942180
    Abstract: A memory system includes semiconductor memory devices and a control device. Each of the semiconductor memory devices includes a first pad to which a first signal is input, a second pad to which a second signal is input, a third pad to which a third signal is input, a memory cell array, a sense amplifier, and a data register. In a first mode, after the first signal is switched, a command set instructing a data out operation is input via the second pad. In a second mode, after the first signal is switched, the command is input via at least the third pad. The control device executes a first operation assigning different addresses to the respective semiconductor memory devices and a second operation causing the modes of the respective semiconductor memory devices to be switched from the first to the second mode.

  • Patent number: 7990723
    Abstract: A housing structure of an acoustic controller, in which a lower case of the controller has an increased rigidity and improved moldability. The lower case is integrally formed by a resin and has a bottom surface thereof disposed to face a tabletop surface when the controller is in a stationarily placed thereon. The bottom surface of the lower case is formed to have a concave-forming portion that defines a concave space communicating with the outside of the controller on the left and right sides thereof and which is upward convex as viewed when the controller is stationarily placed, thus increasing the rigidity of the lower case. Bosses and vertical ribs formed to project upward from a horizontal part of the concave-forming portion of the lower case each have a reduced height, thereby improving the moldability of the lower case.

  • Patent number: 7733660
    Abstract: A housing structure of an acoustic controller having a lower case which is lightweight, high in the degree of freedom in shape design, and capable of suppressing a deformation of side walls thereof after being molded. The lower case is integrally formed from resin into a rectangular dish shape having front, rear, left, right, and bottom plates. An upper unit is attached to an open upper part of the lower case. The left and right plates of the lower case have upper parts thereof formed into brim portions protruding outward in the left-to-right direction. Front and rear parts of each brim portion are further protruded outward and formed into flanges that function as mounting portions used for mounting the acoustic controller to a rack.
