摘要： A method for storing data multi-level cell (MLC) memory includes receiving data to be stored. The received data is divided into units of x bits, where x is an integer greater than or equal to 3. Each of the units of x bits is stored over a span of y memory cells of the MLC memory. Here, y is an integer greater than or equal to 2. At least one bit of each of the x bits is stored only partially in a first memory cell of the span of y memory cells and the at least one bit is also stored, only partially, in a second memory cell of the span of y memory cells such that the at least one bit cannot be interpreted without reading both the first and second memory cell of the span of y memory cells.

摘要： Example embodiments disclose methods and apparatuses for encoding and decoding data in a memory system. In an encoding method according to an example embodiment of inventive concepts, a codeword is generated based on a combination of data to be stored and auxiliary data according to stuck cells and an encoding matrix based on information regarding coordinates of the stuck cells and values of the stuck cells. The generated codeword includes data corresponding to the values of the stuck cells at addresses corresponding to the coordinates of the stuck cells. In a decoding method according to an example embodiment of inventive concepts, data may be generated by multiplying an inverse matrix of the encoding matrix used for encoding by the codeword.
