Systems and methods for error checking and correcting for memory module
Methods for error checking and correcting (ECC) in a memory module including at least one memory unit are provided. The method includes the steps of: receiving input data from the memory unit; performing, by a first ECC module, a first ECC operation to the input data and generating a decoding result which indicates whether decoding was successful; and determining whether to activate a second ECC module to perform a second ECC operation to the input data according to the decoding result, wherein the first and second ECC modules respectively utilize a first method and a second method, wherein the first method applies a ECC with a first fault tolerant quantity for error correction and the second method applies a ECC with a second fault tolerant quantity for error correction, and the second fault tolerant quantity is larger than the first fault tolerant quantity.
