    摘要: A method for operating a controller may include storing a pseudo noise (PN) sequence provided from a PN sequence generator in an i-th area of a seed table and cyclically shifting the PN sequence from the i-th area to an (i+1)-th area in the table to form the table. The table may include row and column areas. A method for operating a controller may include receiving a sequence from a sequence generator, splitting the sequence into seed units, storing split sequences in a j-th area of the seed table, and forming the table including the seed units corresponding to the split sequences stored in the j-th area. A method for operating a controller may include storing a sequence provided from a sequence generator in a seed table that includes a plurality of areas and cyclically shifting the sequence in the table until a seed is formed in each area.

    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.
