NO RATINGS
There's also the question as to id a particular radiation event matters or not. Suppose you have a space system that is taking pictures, storing them in on-chip memory, performing DSP on them, and shending them to Earth. If a radiation event causes a bit to flip in the middle of a 10megabit picture ... who really cares -- that will be filtered out by the DSP anyway -- so I probably woyuldn;t worry about protecing thsi memory

 

By comparison, if I have another block of on-chip memory that is storing my system flight parameters -- then I will use ECC, TMR, and memory scrubbing techniques to keep tha tdata pristine...
