  • Word line driving circuit for semiconductor memory device
    Patent number: 6337831
    Abstract: A hierarchical word line driving circuit for a semiconductor memory device can reduce a sub-threshold voltage leakage current because a sub-word line is disabled at a back bias voltage, overcome a layout penalty because an additional NMOS transistor for preventing the sub-word line from floating is not employed, and sufficiently obtain a line pitch passing above the sub-word line.
