| Abstract: | Due to long operation latency of NAND Flash ,A Multi-level Parallel Architecture is applied to improve the throughput of the storage system .With channel level ,chip level,LUN level and plane level interleaving and cluster-mapping scheme ,flash storage is designed based on the Multi-level Parallel architecture .The evaluation results implemented on a prototype board show that the read and write performance of the system based on the proposed architecture could be improved . |

| Keywords: | storage disk multi-level parallel NAND flash cluster-mapping scheme |
