Abstract
Disclosed are ferroelectric and ferromagnetic noise isolation structures that reduce electromagnetic interference and noise in integrated circuit devices and system architectures. Representative structures comprise two or more devices that are vertically disposed relative to one another, and a thin ferroelectric or ferromagnetic film layer disposed between the respective devices that isolates electromagnetic energy coupling from one device to another.
