In this work, we consider high-rate error-control systems for storage devices using multi-level per cell (MLC) NAND flash memories. Aiming at achieving a strong error-correcting capability, propose block-wise parallel/serial concatenations of short Bose-Chaudhuri-Hocquenghem (BCH) codes with two iterative decoding strategies, namely, hard-decision (IHDD) and reliability based (IRBD). It will be shown that simple but very efficient IRBD is possible by taking advantage unique feature the...
