In this work, we study high-rate error-control systems with serial quasi-primitive block-wise concatenated Bose-Chaudhuri-Hocquenghem (BC-BCH) codes for storage devices using multi-level per cell (MLC) NAND flash memories. The system targets at achieving a strong error-correcting capability when only hard-decision channel outputs are available. Error-rate performance of the proposed system is compared with those of systems based on various coding schemes including LDPC codes.
