COSMIC RAY ERRORS. “One experiment measured the soft error rate at the sea level to be 5,950 failures in time (FIT) per DRAM chip. When the same test setup was moved to an underground vault, shielded by over 50 feet (15 m) of rock that effectively eliminated all cosmic rays, zero soft errors were recorded. In this test, all other causes of soft errors are too small to be measured, compared to the error rate caused by cosmic rays.”
