ECC memory

(Error Correcting Code)- Stray particles from radiation(mainly CBR- Cosmic background radiation) are responsible for bits spontaneously changing states from 1 to 0 or viceversa. This can cause errors in the data stored on the RAM module, and for critical financial and scientific systems this is unacceptable. ECC RAM, for example, includes modules capable of detecting and correcting these errors. See also: Corruption
