Error-correcting code memory (ECC memory) these kinds of memories can detect and correct errors but only in single bit of the byte, in this case, if there is more than one bit, for example, two bits, the ECC memory can detect the error but cannot fix it, there are some memories without ECC can detect errors but not correct it.
