Can ECC correct errors?
Error correction code (ECC) checks read or transmitted data for errors and corrects them as soon as they are found. ECC is similar to parity checking except that it corrects errors immediately upon detection.
Which is the most efficient error correction method?
The best-known error-detection method is called parity, where a single extra bit is added to each byte of data and assigned a value of 1 or 0, typically according to whether there is an even or odd number of "1" bits.
How many errors can ECC detect?
An ECC-capable memory controller can generally detect and correct errors of a single bit per word (the unit of bus transfer), and detect (but not correct) errors of two bits per word.
Which algorithm is used for error detection and correction?
Cyclic Redundancy Check (CRC)
This technique involves binary division of the data bits being sent. The divisor is generated using polynomials. The sender performs a division operation on the bits being sent and calculates the remainder.
