Ok, thanks Tim, that gives me a bit more understanding of the issue. But what is the process used to control the current sent to the gate on the memory? In a memory transistor you change the current at the gate to allow (or prevent) a connection between the source and the drain, right? Maybe a few switches can control the switching of hundreds or even thousands of these gates, but I would think the gates, being dependent on the logic or control switches for their own switching could not switch faster then the logic or control switches. If the control switches have a similar source, gate, and drain setup, then something would need to control the current to their gate. If the highest level control switches do use a design like that then what control's the current change on their gates. I can't imagine it would be a physical switch because it would be too slow (and probably too big even if you only need a very few circuits at this level), but I can't understand how a transistor that operates based on currents being applied at a gate could switch without something external to it controlling the switching. It might be that to really understand it I need to develop a solid basic understanding of the whole subject. Either actually taking, or doing independent reading equivalent to a "Electrical engineering 101" class and a "Basics of integrated circuits" class, but while I am interested in the answer, I'm not sure I want to put that much time in to researching it.
