Abstract
A signal transmission system is constructed to transmit data over a signal transmission line without requiring precharging the signal transmission line for every bit, by eliminating the intersymbol interference component introduced by preceding data. The signal transmission line has a plurality of switchable signal transmission lines organized in a branching structure or a hierarchical structure, at least one target unit from which to read data is connected to each of the plurality of signal transmission lines, and a readout circuit including a circuit for eliminating the intersymbol interference component is connected to the signal transmission line, wherein the intersymbol interference component elimination circuit reduces noise introduced when the signal transmission line is switched between the plurality of signal transmission lines, and thereby provides a smooth intersymbol interference component elimination operation when the signal transmission line is switched. This makes continuous readout possible and achieves an increase in the overall speed of the signal transmission system.
