A mathematical approach to NAND flash-memory descrambling and decoding

New mathematical techniques for analysis of raw dumps of NAND flash memory were developed. These techniques are aimed at detecting, by analysis of the raw NAND flash dump only, the use of LFSR-based scrambling and the use of a binary cyclic code for errorcorrection. If detected, parameter values for both LFSR and cyclic error-correcting code are determined simultaneously. These can subsequently...

Low energy error correction of NAND Flash memory through soft-decision decoding

The raw bit error rate of NAND Flash memory increases as the semiconductor geometry shrinks for high density, which makes it very necessary to employ a very strong error correction circuit. The soft-decision-based error correction algorithms, such as low-density parity-check (LDPC) codes, can enhance the error correction capability without increasing the number of parity bits. However, soft-dec...

Polar-Coded Forward Error Correction for MLC NAND Flash Memory Polar FEC for NAND Flash Memory

With the ever-growing storage density, high-speed, and low-cost data access, flash memory has inevitably become popular. Multi-level cell (MLC) NAND flash memory, which can well balance the data density and memory stability, has occupied the largest market share of flash memory. With the aggressive memory scaling, however, the reliability decays sharply owing to multiple interferences. Therefor...

Reliability of 3D NAND Flash Memories

Reliability represents one of the major antagonist towards the unstoppable technological evolution of hyperscaled NAND memories, since the correct operations must be assured throughout the entire lifetime. In particular, the ability of keeping unaltered the stored information even after a consistent number of write operations and for long times must be guaranteed. A growth of the memory devices...

Developing NAND Flash-Memory SSD-Based File System Design

This paper focuses on I/O optimizations of N-hybrid (New-Form of hybrid), which provides a hybrid file system space constructed on SSD and HDD. Although the promising potentials of SSD, such as the absence of mechanical moving overhead and high random I/O throughput, have drawn a lot of attentions from IT enterprises, its high ratio of cost/capacity makes it less desirable to build a large-scal...
