報(bào)告摘要:
Nowadays, flash memory-based storage systems are widely used in mobile phones, personal computers and other systems. Although flash memory has the advantages of shock resistance, non-volatility and high access performance, its cost is still high, which hinders the use of full-flash memory systems. In order to reduce market costs, a large number of high-density flash memories are studied and developed, such as triple-level per cell (TLC) flash memory and 3D NAND flash memory. This, however, causes worse data reliability. In order to relieve reliability problem caused by technology scaling, LDPC codes have been widely applied to provide high error correction capability. However, the increased error correction capability has to trade with high read latency, which largely decreases read performance of SSDs. This report introduces several novel techniques to optimize this problem.
