By detecting and correcting single-bit errors, ECC server memory ... WebJan 6, 2010 · Nonparity systems have no fault tolerance at all. The only reason they are used is because they have the lowest inherent cost. No additional memory is necessary, as is the case with parity or ECC techniques. Because a parity-type data byte has 9 bits versus 8 for nonparity, memory cost is approximately 12.5% higher.
