Abstract
An error correction method for correcting an first ECC code from a storage unit, comprising: (a) marking at least a first part of the first ECC code according to a correction result generated by correcting error of the first ECC code, to generate a first error correction reference information; and (b) marking at least a second part of the first ECC code according to the first error correction reference information to generate a second error correction reference information.
Claims52
An error correction method for correcting a first ECC code from a storage unit, comprising:
- (a) marking at least a first part of the first ECC code according to a correction result generated by a first correcting step that corrects error of the first ECC code, to generate a first error correction reference information, wherein the first error correction reference information identifies a location of the error corrected by the first correcting step;
- and
- (b) marking at least a second part of the first ECC code according to the first error correction reference information to generate a second error correction reference information.
An error correction method for correcting a LDC code from a storage unit, comprising:
- (a) marking at least a first part of the LDC code according to a correction result generated by correcting error of the LDC code, to generate a first error correction reference information;
- (b) marking at least a second part of the LDC code according to the first error correction reference information to generate a second error correction reference information;
- and
- (c) correcting a part of the LDC code, which has error that was not corrected in the step (a), according to the second error correction reference information.
An error correction apparatus for correcting an first ECC code from a storage unit, comprising:
- an error correction unit, for performing a first error correction operation to correct error of the first ECC code;
- and
- an error correction reference information generator, for marking at least a first part of the first ECC code according to the first error correction operation, to generate a first error correction reference information;
- and for marking at least a second part of the first ECC code according to the first error correction reference information to generate a second error correction reference information;
- wherein the first error correction reference information identifies a location of the error corrected by the first correcting step.
An error correction apparatus for correcting a LDC code from a storage unit, comprising:
- an error correction unit, for performing a first error correction operation to correct error of the LDC code;
- and
- an error correction reference information generator, for marking at least a first part of the LDC code according to the first error correction operation, to generate a first error correction reference information;
- and for marking at least a second part of the LDC code according to the first error correction reference information to generate a second error correction reference information;
- wherein the error correction unit further performs a second error correction operation to correct a part of the LDC code, which has error that was not corrected in the first error correction operation, according to the second error correction reference information.
