Abstract
A non-volatile storage apparatus comprises a non-volatile memory structure and a plurality of I/O pads in communication with the non-volatile memory structure. The I/O pads include a power I/O pad, a ground I/O pad and data/control I/O pads. The non-volatile storage apparatus further comprises one or more capacitors connected to the power I/O pad and the ground I/O pad. The one or more capacitors are positioned in one or more metal interconnect layers below the signal lines and/or above device capacitors on the top surface of the substrate.
