US Patent 7463054 Data bus charge-sharing technique for integrated circuit devices

A data bus charge-sharing technique for integrated circuit devices may be implemented utilizing two voltage regulators to generate constant voltages VEQ1 and VEQ2, which are in the particular exemplary implementation disclosed, approximately 0.9 times a supply voltage VCC and 0.1 times VCC, respectively. One set of signals switches between VCC and VEQ1, and a second set of signals switches between VEQ2 and 0V. Charge-sharing between the two sets of signals is accomplished by the unique configuration of the voltage regulators.
