Abstract
A DNA-based storage system implements a sub-code architecture for error correction capability (ECC) purposes. The sub-code architecture enables a long DNA strand to be divided into two or more short DNA strands. Each short DNA strand has its own unique parity information. Additionally, each short DNA strand is separately decodable from the other short DNA strands. The parity information associated with a particular short DNA strand is used to correct any errors that occur or are detected during the decoding process. However, if the decoding and error correction processes are not successful using the parity information associated with the particular short DNA strand, global parity information is used to decode the particular short DNA strand and correct the errors. Global parity information includes information from each short DNA strand and the parity information associated with each short DNA strand.
