ABSTRACT:
Apparatus and methods store stream-based error recovery data for a memory array, such as a NAND flash array. Conventionally, data is block coded per industry specification and stored in the memory array. Within the limits of the block code, this technique provides for correction of errors. By applying a stream-based inner code, that is, concatenating the outer block code with an outer code, the error correction can be further enhanced, enhancing the reliability of the device. This can also permit a relatively small-geometry device to be used in a legacy application.
