In some embodiments, the secondary ECC module 304 may encode or otherwise provide error correction for access data, using at least a secondary error correcting code. Thus, in further embodiments, the secondary ECC module 304 may determine whether the ECC chunk is correctable using the secondary error correcting code by attempting to decode the access data. In certain embodiments, as described above, the primary ECC module 302 may encode data other than the access data using additional ECC chunks using the primary error correcting code without the secondary error correcting code, and the secondary ECC module 304 may not operate to encode and/or decode the additional ECC chunks. Thus, in some embodiments, the non-volatile memory device 120 may use two error correcting codes to store the access data with a high degree of reliability, but may use one error correcting code to store other data for easy retrieval, with reduced overhead, or the like. ECC chunks encoding data and access data are described in further detail below with regard to FIG. 5A, FIG. 5B, and FIG. 5C.
