  • Patent number: 7423623
    Abstract: An image display displays image data on an image display part constructed by a display pixel array. In an image display in which image data input means for inputting image data so that the display pixel array has two neighboring areas having different frame rates (>0) is provided or image data is displayed on an image display part constructed by a display pixel array, there is provided image data input means which can input at least one moving image data and at least one still image data into the image display part at different frame rates (>0). A high precision image display can be realized hardly changing a display pixel rewriting speed. A moving image signal output circuit and a still image signal output circuit output image data to the display pixel array, and they are provided as circuit configurations independent of each other.

  • Patent number: 7254068
    Abstract: Parasitic capacitances formed between bit lines to which signals are to be read out of memory cells and a signal transmission line arranged above them are to be reduced. Second complementary global bit lines for transmitting data read out of memory cells MC via complementary bit lines are arranged above a memory cell array. Each second global bit line is so arranged that a triangle having as its vertexes the center of the section of one of the complementary bit lines, that of the section of the other and that of the section of the second global bit line arranged directly above these complementary bit lines be an isosceles triangle.
