Correcting Errors in MLCs with Bit-fixing Coding




Abstract: Codes that correct limited-magnitude errors for multi-level cell nonvolatile memories have received interest in recent years.This work proposes a new coding scheme that generalizes a known result and works for arbitrary error distributions.In this scheme, every cell\'s discrete level is mapped to its binary representation,where each bit in the binary form belongs to a different ECC.The codewords are decoded sequentially to correct errors.An optimized cell-level labeling scheme is also studied.
