Enhanced Precision Through Multiple Reads for LDPC Decoding in Flash Memories
Jiadong Wang, Kasra Vakilinia, Tsung-Yi Chen +5
Multiple reads of the same Flash memory cell with distinct word-line voltages provide enhanced precision for LDPC decoding. In this paper, the word-line voltages are optimized by m…
LDPC Decoding with Limited-Precision Soft Information in Flash Memories
Jiadong Wang, Guiqiang Dong, Thomas Courtade +3
This paper investigates the application of low-density parity-check (LDPC) codes to Flash memories. Multiple cell reads with distinct word-line voltages provide limited-precision s…
The Cycle Consistency Matrix Approach to Absorbing Sets in Separable Circulant-Based LDPC Codes
Jiadong Wang, Lara Dolecek, Richard Wesel
For LDPC codes operating over additive white Gaussian noise channels and decoded using message-passing decoders with limited precision, absorbing sets have been shown to be a key f…
Mutual-Information Optimized Quantization for LDPC Decoding of Accurately Modeled Flash Data
Jiadong Wang, Guiqiang Dong, Tong Zhang +1
High-capacity NAND flash memories use multi-level cells (MLCs) to store multiple bits per cell and achieve high storage densities. Higher densities cause increased raw bit error ra…
Designing Nonlinear Turbo Codes with a Target Ones Density
Jiadong Wang, Thomas Courtade, Tsung-Yi Chen +2
Certain binary asymmetric channels, such as Z-channels in which one of the two crossover probabilities is zero, demand optimal ones densities different from 50%. Some broadcast cha…
Absorbing Set Spectrum Approach for Practical Code Design
Jiadong Wang, Lara Dolecek, Zhengya Zhang +1
This paper focuses on controlling the absorbing set spectrum for a class of regular LDPC codes known as separable, circulant-based (SCB) codes. For a specified circulant matrix, SC…
