  • Patent number: 7236385
    Abstract: A DDR SDRAM where unidirectional row logic is associated with and connected to a single memory array instead of being associated with and connected to multiple memory arrays. The unidirectional row logic is located in the outward periphery of its associated array, but is not within a throat region between two arrays. The location of the row logic allows the throat region to include more bidirectional IO circuitry and signal lines servicing two arrays, which increases the performance of the SDRAM. In addition, separate power bussing is employed for the memory arrays and IO circuitry. This prevents noise from the arrays from affecting the IO circuitry and signal lines of the throat region and vice versa.

    Abstract: A power and ground shield mesh to remove both capacitive and inductive signal coupling effects of routing in integrated circuit device. An embodiment describes the routing of a shield mesh of both power and ground lines to remove noise created by capacitive and inductive coupling. Relatively long signal lines are routed in between fully connected power and ground shield mesh which may be generated by a router during the signal routing phase or during power mesh routing phase. Leaving only the odd tracks or the even tracks for signal routing, power mesh (VDD) and ground mesh (VSS) are routed and fully interconnected leaving shorter segments and thereby reducing the RC effect of the circuit device. Another embodiment presents a technique where the signals are shielded using the power and ground mesh for a gridless routing. Another embodiment presents a multi-layer grid routing technique where signals are routed on even grid and the power and ground lines are routed on odd grid.

  • Patent number: 7119383
    Abstract: A semiconductor integrated circuit effectively makes use of wiring channels of wiring formed by a damascene method. When first cells are used, since the M1 power source lines are laid out at positions spaced away from a boundary between the cells, the power source lines are not combined in laying out a semiconductor integrated circuit. As a result, the width of the power source lines is not changed. Accordingly, an interval between the line and a line which is arranged close to the line, determined in response to a line width of the lines, can satisfy a design rule; and, hence, the reduction of the wiring channels can be obviated, whereby the supply rate of the wiring channels can be enhanced, and, further, the integrity of a semiconductor chip can be enhanced.

  • Patent number: 7023070
    Abstract: The present invention prevents electrostatic discharge damage which may occur when a device chip which has a circuit with fuses mounted thereon is packaged by COG packaging, without increasing an area occupied on the device chip. The height from the chip substrate surface to the top face 138b of the chip terminal 103b formed on the chip substrate surface 136 is formed to be higher than the height from the chip substrate surface to the top face 138a of the fuse terminal 103a. By this, an electrostatic discharge occurs at the chip terminal side when packaged in a COG packaging, so an electrostatic discharge does not occur to the fuse terminal side.
