In one embodiment, an ECC chunk may refer to a code word for the primary error correcting code. In various embodiments, the primary error correcting code may be one of various types of error correcting code, such as a block code, a convolutional code, a Bose-Chaudhuri-Hocquenghem (BCH) code, a low-density parity check (LDPC) code, a Hamming code, a Reed-Solomon code, a turbo code, or the like. In a certain embodiment, the primary error correcting code may be a systematic error correcting code, so that each ECC chunk, or code word, may store data received by an encoder for the primary error correcting code, as well as parity bits, or check bits. A systematic error correcting code, as used herein, may comprise an error correcting code that includes or combines the input data in the output ECC code word or chunk, so that the ECC code word or chunk includes the input data directly. This means that the input data (e.g. the message) is readily identifiable in the ECC code word. In other words, the input data (e.g. the message) is either not transformed/encoded or is encoded/transformed with a unity encoding. A non-systematic code, as used herein, may comprise an error correcting code that encodes or transforms the input data so that the encoded output includes the input data encoded together with other ECC check bits (aka parity bits). This means that the input data (e.g. the message) is not readily identifiable in the ECC code word. An ECC chunk generated by a systematic error correcting code may store ECC check bits or parity bits before the non-encoded input data, after the non-encoded input data, or at one or more other locations within the non-encoded input data. An ECC chunk generated by a non-systematic error correcting code may provide error detection and/or correction using the data encoding itself, with or without separate ECC check bits. In a non-systematic error correcting code, the output may comprise a code word which itself may be considered the ECC check bits.
