Abstract
Decoupling capacitance of at least one shared capacitor is distributed among a plurality of voltage sources for enhanced performance with minimized area of a semiconductor device. The high nodes and the low nodes of such voltage sources each comprise at least two distinct nodes for lower noise at the voltage sources. The present invention is applied to particular advantage for coupling a variable number of shared capacitors to a data charge voltage source depending on a bit organization of the semiconductor device.
