Abstract(in English) | A TLC-NAND flash provides a low cost and high capacity memory solution. However the reliability and access latency of TLC NAND flash are degraded from MLC NAND flash. This paper proposes TLC/MLC NAND flash hybrid and exchangeable storage arrays. To reduce accesses to TLC NAND flash, the stored data is screened and only the static frozen data is stored into TLC NAND flash with a Round-Robin frozen data collecting algorithm (RR-FDCA). As a result, the proposed storage array can achieve 29% write energy saving and 56% write performance enhancement with 17% cost reduction, compared with the conventional MLC-only SSD. |
