  • Self-bootstrapping word-line driver circuit and method
    Patent number: 6025751
    Abstract: Aspects for self bootstrapping word-line driver circuitry are provided. In a circuit aspect, a word-line driver circuit for a memory cell in a semiconductor memory includes a signal input means, the signal input means comprising a first plurality of transistors, the first plurality of transistors receiving an input voltage signal higher than a voltage supply signal of the semiconductor memory. The circuit further includes a signal output means, the signal output means comprising a second plurality of transistors coupled to the first plurality of transistors and providing an output drive signal sufficient for the memory cell.
