ECC (Error Correction Codes) is a method used to detect and correct errors introduced during data storage or transmission. Certain kinds of RAM chips inside a computer implement this technique to correct data errors and are known as ECC Memory. ECC Memory chips are predominantly used in servers rather than in client computers. Memory errors are proportional to the amount of RAM in a computer as well as the duration of operation.
