In some safety related contexts you do have bitflip protection on the software level. E.g. you write every variable together with it's complement, to see if a random bit flip occurred. It's quite a lot of work, but if you have a long running embedded system, or a lot of the same, e.g. in cars, the incidence of bit flips increases. This is it course additional to other protection mechanisms.
