 The recovered data may be re-written to exactly the same physical location, to spare blocks elsewhere on the same piece of hardware, or the data may be rewritten onto replacement hardware.DRAM memory may provide stronger protection against soft errors by relying on error correcting codes.Such error-correcting memory, known as "ECC" or "EDAC-protected" memory, is particularly desirable for mission-critical applications, such as scientific computing, financial, medical, etc.
