Research Abstract

We developed and characterized new signal processing and coding methods to improve the capacity and longevity of flash memories. We investigated optimal WOM code constructions based on lattice theory and developed an optimal code construction using the intersection of a lattice and some shaping region. To increase reliability, our coded modulation method combining lattices and Reed-Solomon codes improves the SNR by 1.8 dB over existing flash memory codes using BCH codes. And, we developed an effective channel quantization method based on the maximization of mutual information.
