Well, the original ones were as you say, but there was a lot
of work going on to make
massive improvements. Yes, you sure would not want to use
them as main CPU

memory sticks are used
today, they might have significant advantages.

Yes, the FRAM looks very interesting, they are just starting

other technologies. But, they may catch up.
