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.

Abstract: A semiconductor memory circuit which realizes a source follower having a voltage gain equal to one, a decrease in the time necessary for the source follower to reach its full output voltage. Furthermore, the multiple-valued or analog output voltage can be easily converted to a binary-digital form with this memory circuit. This semiconductor circuit comprises at least an MOS transistor. A multiple-valued or analog data line is connected to the inputs of multiple-valued comparators, the outputs of said comparators are coupled capacitively to the input gate of a source-follower circuit, and the output of said source-follower circuit is fed back to the data line.
