In spite of the mature cell structure, the memory controller architecture of Multi-level cell (MLC) NAND Flash memories is evolving fast in an attempt to improve the uncorrected/miscorrected bit error rate (UBER) and to provide a more flexible usage model where the performance-reliability trade-off point can be adjusted at runtime. However, optimization techniques in the memory controller architecture cannot avoid a strict trade-off between UBER and read throughput. In this paper, we show that co-optimizing ECC architecture configuration in the memory controller with program algorithm selection at the technology layer, a more flexible memory sub-system arises, which is capable of unprecedented trade-offs points between performance and reliability.

Abstract: | In spite of the mature cell structure, the memory controller architecture of Multi-level cell (ML...C) NAND Flash memories is evolving fast in an attempt to improve the uncorrected/miscorrected bit error rate (UBER) and to provide a more flexible usage model where the performance-reliability trade-off point can be adjusted at runtime. However, optimization techniques in the memory controller architecture cannot avoid a strict trade-off between UBER and read throughput. In this paper, we show that co-optimizing ECC architecture configuration in the memory controller with program algorithm selection at the technology layer, a more flexible memory sub-system arises, which is capable of unprecedented trade-offs points between performance and reliability. |
