OTPROMs aka OTP EPROMs are floating gate 2764/27128/etc EPROMs with no window, so they can't be erased with UV light (though, as we can see here, age can still cause them to become slowly erased).
They can be erased with X-rays. EPROMs were originally designed to be erased that way. There are problems with that approach, however. (hence the move to UV) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
