Full name Error Checkingand Correcting. It is also implemented by adding bits to the original data bits. For 8-bit data, 1 bit is used for Parity test and 5 bits are used for ECC. This extra 5 bits is used to reconstruct the wrong data. When the number of bits of data doubles, Parity also doubles, while ECC only needs to increase one bit. When the data is 64 bits, the same ECC and Parity bits are used (all 8). Where Parity can only detect errors, ECC can correct most errors. If you are working properly, you will not find out that your data is wrong. Only after the memory error correction can the computer's operating instructions continue to execute. Of course, the performance of the system has been significantly reduced during error correction, but this error correction is very important for applications such as servers. The cost of ECC memory is much more expensive than ordinary memory.
