ABSTRACT:
A method and apparatus of precharging data and/or address lines each having a large number of loads to a voltage midway between high and low using a source-follower configuration, and optionally driving only one-half of the precharge circuit based on a previous logical value on the line being precharged. In some embodiments, a driver circuit drives an output node either high or low during a first phase of each clock cycle, and a precharge circuit then precharges the output node to an intermediate voltage during a second phase of the clock cycle in preparation for the following clock cycle. Some embodiments include source-follower configured FETs to precharge, wherein these FETs turn off once the output voltage reaches an intermediate value.
