Abstract: 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.

Abstract: A method of operating a data storage device includes generating at least one pseudo noise (PN) sequence using logical information and physical information for the data storage device. The method also includes converting first data into second data using the at least one PN sequence. The logical information may be a logical address for the data storage device, and the physical information may be a physical address for the data storage device.

Abstract: A method of operating a memory controller is provided. The method includes determining a data state based on an input stream including multiple alphabet letters, converting a part of the input stream, which corresponds to a conversion size, into alphabet letters in a lower numeral system when the data state is determined to be a first state among multiple predetermined data states, inserting one of the converted alphabet letters into the input stream, and outputting each of the alphabet letters in the input stream as is when the data state is determined to be a second state among the predetermined data states.
