Abstract
An apparatus is provided for precharging a conductor within a bus containing a plurality of conductors. The apparatus comprises a precharge driver which precharges alternating pairs of conductors to opposite rail voltages. By precharging pairs of conductors to alternating rails, the present apparatus can minimize the speed degradation problems associated with a transitioning target conductor within the bus. Precharging alternating pairs of conductors also minimizes crosstalk noise from transitioning neighbor conductors to a non-transitioning target conductor. The improved dynamic bus thereby demonstrates improvements in speed degradation and crosstalk noise as seen by a transitioning target conductor or non-transitioning target conductor, respectively.
