As someone who did incredibly poorly in high school physics, this line in the article bothered me as well: the study is from the 1990s when the density of memory would have been much lower. I would think the percentage per megabyte has dropped significantly in 30 or so years. It also assumes a constant form factor for the memory, doesn't it?

The energy needed to flip a bit has drastically lowered since the 1990s, and increased density makes bit flip rates increase at some point since a single physical event can flip multiple bits.

So it's not so simple.

Thanks. So I was sort of right only in the exact opposite direction!
