Like interior design layout, like circuit design layout? And (I think) the copper circuits are so close that quantum leaps can occur -- electrons can just decide to jump from one piece of copper to another, straight through silicon or anything else, simply because the copper is so close. This means a VCC line can be giving charge to an unpowered neighboring circuit or memory cell without magnetically affecting it.
