Abstract
A semiconductor integrated circuit includes a plurality of signal wires and an array of capacitor-based memory cells. The capacitors of the memory cells are electrically coupled to a common voltage source node where a voltage source provides supply power to the array. Shield wires positioned proximal to the signal wires are electrically coupled to the common voltage source node. A shield capacitor may be provided between the signal wires and the common voltage source node to provide further noise suppression.
