Signal transmission circuit

摘要

A signal transmission circuit suitable for a memory device includes a signal generating section for generating a data signal from a power source, a pair of signal transmission lines for transferring the data signal by transferring signal charge associated by the data signal, an amplifying section for amplifying the data signal transferred by the signal transmission lines, and a precharge section for precharging the output of the signal generating section, the pair of signal transmission lines and the output of the amplifying section to a median potential level between the potential levels of the power source. The precharge section provides power saving as well as a larger noise margin.
