    摘要: Provided is a data processing method in a semiconductor memory device. The data processing method arranges data, which is to be programmed in a row and column of a nonvolatile memory device, in a row or column direction. The data processing method encodes the programmed data into a modulation code in the row or column direction such that adjacent pairs of memory cells of the nonvolatile memory device are prevented from being programmed into first and second states.

    摘要: A memory device includes a plurality of multi-bit memory cells. A plurality of input data bits are encoded according to an error correction code to generate a codeword including a plurality of groups of bits. Respective ones of the plurality of multi-bit memory cells are programmed to represent respective ones of the groups of bits of the codeword. The groups of bits of the codeword may be groups of consecutive bits. In some embodiments, the multi-bit memory cells are each configured to store in bits and a length of the codeword is an integer multiple of m. Data may be read from the multi-bit memory cells in page units or cell units to recover the codeword, and the recovered code word may be decode according to the error correction code to recover the input data bits.
