Balanced Modulation for Nonvolatile Memories [article]

Hongchao Zhou, Anxiao Jiang, Jehoshua Bruck
2012 arXiv   pre-print
This paper presents a practical writing/reading scheme in nonvolatile memories, called balanced modulation, for minimizing the asymmetric component of errors.  ...  Balanced modulation has suboptimal performance for any cell-level distribution and it can be easily implemented in the current systems of nonvolatile memories.  ...  It enables balanced modulation to be adaptive to a variety of channels characters, hence, it makes balanced modulation applicable for most types of nonvolatile memories.  ...
