When I was a CS student, a little more than a decade ago, we learnt what ECC was and how it worked. Interestingly, I remember that we were taught that ECC was and should be everywhere.

From physical storage to data transfer protocols, we were said you really wouldn’t bypass ECC anywhere if you wanted things to work reliably against the hard physical world. It was like a basic CS rule.

And still, there we are, still arguing that some reliability is needed into objects as critical as DRAM chips.
