Error Correction Code is referred to as ECC. By identifying and fixing transmission mistakes, ECC is used to validate data transfers. It is frequently employed by RAM processors with forward error correction (FEC), which guarantees that all data sent to and from the RAM is transferred accurately.

Parity RAM, which has a parity bit that verifies the data being sent, is comparable to ECC RAM or memory. The extra parity bit, which can have a numerical value of 1 or 0, is transmitted with the data. The transfer of the data may need to be repeated if the value of the parity bit does not match the value of the data it represents. Similar to other error correction techniques, ECC employs a more sophisticated system that can fix communication mistakes in real time.

ECC memory can be slower than non-ECC RAM and simple parity RAM because it needs more computation. ECC Memory, on the other hand, offers more dependable data exchanges, which boosts system reliability. ECC memory may therefore be used in high-end computers and laptops to reduce failures and system outages.
