  • Pattern layout method of semiconductor device
    Patent number: 6820246
    Abstract: In the driver for driving display having an anode driver, a cathode driver, and memory portions of a semiconductor device of the invention, anode driver regions connected to the memory portions are laid out equally in the chip, and SRAMs are arranged equally in the vicinity of each of anode driver regions so that drawing of wiring becomes easy and size of the chip is miniaturized.
    Type: Grant
    Filed: February 21, 2002
    Date of Patent: November 16, 2004
    Assignee: Sanyo Electric Co., Ltd.
    Inventors: Yoshinori Hino, Naoei Takeishi, Yoshitaka Haraguchi
