Also wrong, an unfortunate characteristic of programmable devices is
a nasty tendency to grow back fuses after they are blown.  This has
never happened to me personally, but from all the press it gets
(usually in the form that "our fuses have a much better chance of not
growing back than generic manufacturer abc") I would think it to be
somewhat of a problem.  Note that I have never seen a semiconductor
manufacturer boast about how much longer his EPROMs keep their memory
over generic manufacturer abc...
