| Abstract(in English) | A hybrid storage architecture of ReRAM and TLC (3bit/cell) NAND Flash with RAID-5/6 is developed to meet cloud data-center requirement of reliability, speed and capacity. The storage controller enhances reliability and performance through five techniques. (i) flexible R_ (FR), (ii) adaptive asymmetric coding (AAC), and (iii) verify trials reduction (VTR), are applied to ReRAM to improve the bit-error rate (BER) by 69% and performance by 97%. Techniques (iv) balanced RAID-5/6 and (v) bits/cell optimization (BCO) are applied to TLC NAND to reduce the failure rate by 98% and extend the lifetime by > 22×, respectively. |
