Abstract

Embodiments of the invention generally related to arrangements of decoupling capacitor arrays in an integrated circuit. A decoupling capacitor array may include a plurality of bit lines that are electrically coupled to each other, a plurality of word lines that are electrically coupled to each other, and a plurality of decoupling capacitors, each decoupling capacitor coupled to a respective bit line and word line. The decoupling capacitor array may further include an access circuit electrically coupled to the plurality of word lines and a power grid, the access circuit being configured to either connect or disconnect the decoupling capacitor array to the power grid based on a control signal.
