ECC (Error Correction Code)

Error Correction Code modules are an advanced form of Parity detection often used in servers and critical data applications. ECC modules use multiple Parity bits per byte (usually 3) to detect double-bit errors. They also will correct single-bit errors without creating an error message. Some systems that support ECC can use a regular Parity module by using the Parity bits to make up the ECC code. However, a Parity system cannot use a true ECC module.
