Graphically visualizing the erasure of a 16kbit #EPROM with a UV source in 16 seconds!

This time lapse shows all of the bits being flipped from 0 to 1 over about a 24 minute period. The first bit flips at 8 minutes.

What's fascinating to me is the bits "twinkle" as they flip back and forth before settling.

@paulrickards Oh, that brings back memories. I did the same thing about a decade ago - https://www.youtube.com/watch?v=eafhFs-ZOgs

Did not expect the twinkling either.

What happens when you expose a memory chip to UV?

@theartlav Cool! Interesting to see the same basic patterns emerging with the solid vertical lines being the last to flip.
