11. If detected, a soft error may be corrected by rewriting correct data in place of erroneous data. 12. This is called a " soft error , " because it does no permanent damage to the chip. 13. In the context of circuit operation, this erroneous output value may be considered a soft error event. 14. In a computer's memory system, a soft error changes an instruction in a program or a data value. 15. To duplicate a test is one of the most robust methods that exists for generic soft error detection. 16. After observing a soft error , there is no implication that the system is any less reliable than before. 17. In electronics and computing, a "'soft error "'is a type of error where a signal or datum is wrong. 18. The chance of encountering a soft error becomes greater the higher a computer is above the earth's surface, Borkar said. 19. Scrub " the memory, by periodically reading all addresses and writing back corrected versions if necessary to remove soft errors . 20. A soft error will not damage a system's hardware; the only damage is to the data that is being processed.
