ABSTRACT:
A circuit for generating a voltage for pre-charging a data line. The circuit receives as input an ON/OFF signal which is typically the data bus line equalization control signal. The circuit also receives a varying power voltage. The circuit includes a bleeder which biases the data line at a voltage differing from said varying power voltage by a constant amount when the circuit is ON. The circuit consumes substantially zero power when OFF.
