> PS - Jinx I also read the question as EEPROM at first ;-)

I'm sure John means EEPROM. There probably is some in-
circuit usage of EPROM but EEPROM would be much more
usual these days. Although I think un-windowed OTPs are
EPROM. I guess not having to include the "Electrically" part
would make it cheaper. From what I can gather, the distinction
between NV families is often blurry. There are many technologies
to make NV and one family could simply be a minor variant of
another
