Abstract
A method for checking reading errors of a memory includes receiving a first data fragment and accordingly generating a first ECC and a first count index; writing the first data fragment, the first ECC and the first count index into a memory; reading the first data fragment from the memory as a second data fragment, generating a second ECC and second count index according to the second data fragment; determining whether the first count index and second count index are equal; determining whether the first ECC and the second ECC are equal; and outputting the second data fragment when the first count index is equal to the second count index and the first ECC is equal to the second ECC.
