Like, very interesting article. It also mentions bit flips.
I think the major protection against bit flips is to use larger structure sizes. Like, today’s desktop computers use structure sizes around 2 nm or sometimes even less than that. Which means you only need to shift a few electrons around to cause a bit flip. If you use larger wires inside the processor, they store more electrons so it takes more energy to flip them around. So there’s a much much smaller number of radiation particles that have a minimum of that energy, so lower risk of bit flips.
Does anybody have actual numbers on the structure sizes needed to effectively prevent bit flips? I mean, outer space missions like NASA flights already need this today.
