Most common cause of memory failures
While reading through some Fujitsu documentation I came across the following: “Soft errors were formerly caused by alpha particles in the IC housing. This can now be precluded for the most part by an improved IC housing. Radioactive gamma radiation from solar eruptions is now the main cause of soft errors. In all probability, pure [...]
