Flash memory device and related programming method

摘要

A nonvolatile memory device comprises a memory cell array configured to store one or more bits per memory cell, a read and write circuit configured to access the memory cell array, a control logic component configured to control the read and write circuit to sequentially execute read operations of a selected memory cell at least twice to output a read data symbol, and an error correcting unit configured to correct an error in the read data symbol based on a pattern of the read data symbol to output an error-corrected symbol.
