Abstract
Example systems and methods for using a multi-tier error correction code distributed among oligos for DNA data storage are described. A data unit is encoded as a set of codewords where each codeword is distributed as symbols on different oligos. The codewords include a set of first tier codewords that include CRC and ECC redundancy data and one or more additional tiers of codewords that include permuted data and corresponding ECC redundancy data. Decoding includes a sequence of decoding iterations between the first tier of codewords and additional tiers of codewords.
