Is this the same effect that was behind the early EPROMs with the window that was covered by stickers?

Both are due to the same photoelectric effect according to Wikpedia, however it doesn't seem like xenon flashes are the most suitable thing to erase those chips and I don't think ultraviolet lights would cause the same issues on the Pi that an xenon flash would.

I never heard that camera flashes could actually erase the EPROM. They just disrupted its operation ... which sounds a lot like parasitic photoelectric effect.
