Traditional Algorithm

NAND flash memory has been successfully employed in storage system due to its advantages such as performance, resistance, and capacity. NAND flash memory based solid state disk (SSD) has started to replace disk in numerous environments. However, the poor endurance offered by these SSDs continues to be their key shortcoming. To improve SSD endurance, we propose a static wear-leveling algorithm with variable threshold (WLVT). In contrast with traditional algorithm with fixed threshold, WLVT adjusts the value of threshold, so that each block can simultaneously reach the erasure times that the manufacturer gives when life of SSD is over. Therefore, available erasure time of each block will be fully utilized when SSD fails. Experimental results show that the endurance of the SSD is significantly improved.

In this paper, we analyzed the endurance of Nand Flash memory and then proposed a level adjusting scheme to use the MLC Flash dynamically to storage different amount of data levels through the entire lifetime. The result shows that the MLC SSD adopting this method could be totally written 4.8X more data than conventional MLC SSD and 16.5% more than SLC SSD.

This paper presents a new architecture SSD based on NVMe (Non-Volatile Memory express) protocol. The NVMe SSD promises to solve the conventional SATA and SAS interface bottleneck. Its aimed to present a PCIe NAND Flash memory card that uses NAND Flash memory chip as the storage media. The paper analyzes the PCIe protocol and the characteristics of SSD controller, and then gives the detailed design of the PCIe SSD. It mainly contains the PCIe port and Flash Translation Layer.
