In the 1970s, Intel couldn't work out what was damaging the DRAM on their microchips.
The cause turned out to be the ceramic that the chip was encased in. It was secretly flipping 1s to 0s.
But how?

Lets take a moment to appreciate that this short actually finished what it was trying to say and wasn't clickbait, with no dependence on video context or resolution. Thanks, Veritasium!

As an engineer my heart and soul goes out to whatever poor dudes had to debug that problem.

This fear of the short by Veritasium being ended abruptly was inside me the whole video. Thank God they ended it

And 40 years later, radiation caused Mario to teleport vertically live on stream in Super Mario 64.

In 1981 My Information Science professor gave a lecture about the limits of VLSI miniaturization due to the possibility of fast charged particles eg cosmic rays flipping bits. I reminded him of this in 2010 when I met him at a conference. His reply was that I had just made his day! "because a student remembered something he said in a lecture"! I remember many things he said in lectures because he would diverge into all sorts of interesting areas.. Eg all numbers are polynomials...

The best part about getting a Veritasium notification is you know the video is guranteed to be interesting and worth your time, plus you get to learn stuff too!

Cosmic rays ( particles ) also caused similar incidents with actually changing program flipped digits .

I work in aviation. This forms a large part of the safety design of the aircraft as the operating altitude makes high energy cosmic rays more likely. Luckily we can mitigate it through software such as storing multiple copies of data (usually triplicate) in different physical areas of memory. It has to be different physical areas of memory, because as memory gets smaller, the likelihood of multiple bit flips from one ray increases.

You said the manufacturing plant was in Colorado, and yet you zoom into Green River in Utah?

At a job some years ago I had installed some thin IC:s on a quite dense PCB but at testing we got very intermittant errors while we moved around it to figure out what the hell was going on. I got an idea and stood so all was in shadow and no issues, when I moved so light came on it the errors started again. We found out that the black casing on some memory chips had been made so thin that light could get through and flip all up. We told that to the manufacturer and 1 month later they had made new chips that did not have this issue anymore. We measured them and they were a little thicker. Later we found out that manye have had this probems with them but we was the only ones who had figure out why because their sell of this chip had suddenly plummit but rose again after they made it thicker.
