Coding method of multi-level memory cell

摘要

A coding method of a multi-level cell, applied to a programming operation of a multi-level memory cell. The multi-level memory cell can store n bits and has 2<n >levels with respect to 2<n >codes. Each code is constructed with n bits. In the coding method, a code to be stored is provided. According to a relationship between the code and level, the multi-level memory cell has a specified level for corresponding code to be stored. The relationship is a correspondence between the 2<n >codes and the 2<n >levels. Two codes corresponding to any neighboring two levels has only a one-bit difference.
