1. An apparatus comprising:

  • one or more memory arrays for storage of data;

    a stream-based coder configured to generate a page of forward error correction coded data of a page of original data intended for storage in the one or more memory arrays such that the coded page of data is larger than the page of original data and such that the original data is not recognizable in the coded data without decoding the coded data;

    a page latch operatively coupled to the stream-based coder, wherein the page latch is at least large enough to hold the page of coded data for writing to the one or more memory arrays; and

    a stream-based decoder configured to decode coded data retrieved from the one or more memory arrays to generate decoded data.
