Abstract:
1. A method of operating a semiconductor structure, said method comprising: providing said semiconductor structure with an array of capacitor modules, wherein each of said capacitor modules comprises a capacitor and a switching device connected to a power supply node, said switching device including a first p-type field effect transistor and a second p-type field effect transistor that are connected in a parallel connection between said power supply node and a node of said capacitor that is present within a same capacitor module as said switching device; and turning on said first p-type field effect transistor that is present within said switching device within a selected capacitor module among said array of capacitor modules, wherein a leakage current through said capacitor within said selected capacitor module triggers turning off said second p-type field effect transistor that is present within said selected capacitor module, whereby said capacitor within said selected capacitor module is electrically isolated from said power supply node after said first p-type field effect transistor within said selected capacitor module is turned off.
