What is Error Correction Code (ECC)?

What does ECC stand for?

Error Correction Code (ECC) checks read or transmitted inFormation for errors and corrects them as quickly as they're observed. ECC is much like Parity Checking except that it corrects errors at once upon detection. ECC is turning into more not unusual inside the discipline of Records garage and commUnity transmission Hardware, mainly with the boom of records Charges and corresponding mistakes.

What Does Error Correction Code Mean?

Error correction code is implemented to statistics garage through the following steps:

1. When a facts byte or phrase is stored in RAM or Peripheral Storage, a code-specifying bit sequence is expected and stored. Each Constant number of bits in line with word has an extra fixed Range of bits to shop this code.
2. When the byte or phrase is known as for studying, a code for the retrieved phrase is calculated in line with the unique Algorithm and then compared to the stored byte’s extra Constant bits.
3. If the codes fit, the Data is error unfastened and is Forwarded for processing.
4. If the codes do now not match, the cHanged bits are caught thru a mathematical algorithm and the bits are imMediately corrected.

Data is not confirmed at some point of its storage duration, but is examined for errors while it's far requested. If required, the mistake correction phase follows detection. Frequent ordinary mistakes on the equal garage deal with imply a everlasting hardware mistakes. In this example, the sySTEM sends the person a message, that's logged to document the mistake viciNity(s).
