What about .ro and .text sections of an executable? I would think
kernel support for that would be required. If its application data,
then all sorts of things are possible like you described. Ive also
seen critical ram variables be stored in triplicate and then
compared/voted just to ensure no silent SEU corruption.

Maybe slightly off topic but... if flash is safer than ram, what about using XIP (where possible, e.g. on NORs)? That would not put .data sections into ram, at least.
