该论文针对大数据存储需求，提出了快速LDPC、动态VTH优化和自动数据恢复等技术，在不修改TLC NAND闪存的情况下，实现了企业级SSD的6倍快速读取和5倍高可靠性，显著降低读取延迟和误码率。
techniques that achieve high speed and high reliability. Quick low-density parity-check (LDPC) reduces the read latency of 1Xnm TLC NAND Flash SSD by 83%. Dynamic VTH optimization and auto data recovery reduce the NAND Flash bit-error rate (BER) by 80% and 18%, respectively. These techniques can be implemented in the SSD controller without circuit overhead. No modification is required to the TLC NAND flash. Enterprise storage demands fast speed and good reliability with high-density for big data applications. Though TLC NAND Flash SSD has the bit cost advantage over MLC (2b/cell) NAND Flash SSD, the adoption in the enterprise market is limited due to its poor speed and reliability. Real-time online analytical processing (OLAP) applications require a quick response from SSD. In
