In the NAND flash memory based Solid-state drives (SSDs), since in-place overwrite is prohibited in NAND flash, the operation called garbage collection (GC) is triggered to reclaim the free space. During GC, all the valid pages in the erase block are copied to another block before the block is erased. This overhead degrades the SSD write performance when the number of valid pages is large. In this paper, the address remapping technology to suppress the GC overhead, LBA scrambler, is proposed to improve the SSD performance. With LBA scrambler, 20.0% SSD write performance improvement, 4.3% energy consumption reduction and 3.6% lifetime enhancement are obtained. |
