Not all circuits are equally sensitive. The parts that are known to be sensitive or critical are protected by redundancies and error checking, which are probabilistic protection. You haven't completely eliminated the possibility of corruption, just made it incredibly unlikely. Refreshing your inputs is another form of probabilistic protection focused on mitigating the consequences.
- MarkusQ 10mo agoWhy not ECC though? Unless this is a latched output of a robust system being held for use by another robust system I guess?
- AlotOfReading 10mo agoECC is one of the probabilistic protections I was talking about.
- adrian_b 10mo agoIn another HN thread it was said that since several years there is in production a new model of the affected module that has ECC. Despite that, most of the existing planes have an older model, which has not been upgraded.
