Bug fixing code

ECC Memory

Error-Correcting Code, self-correcting code or self-checking code (Error-Correcting Code, ECC) serves to guarantee the integrity of the data.

Adding a single parity bit is not always enough for data that is constantly moving around, especially in the case of data transmission over long distances, where the transmitted signals are exposed to electrical interference (for example: in a computer network, where data travels from one computer to another that may even be in another country).

This problem has led to the development of code that catches more than one bug and even fixes the bugs it finds.

Some of these techniques have been developed by the American engineer Richard W. Hamming, and are known as Hamming Codes.
