摘要： A method of modifying data sequences in a memory system comprises receiving program data having a first data sequence, and determining whether the received first data sequence matches one of “m” predefined sequences stored in the memory system. The method further comprises replacing the received first data sequence with a replacement sequence upon determining that the received first data sequence matches one of the “m” predefined sequences, and outputting the replacement sequence from the memory system. The replacement sequence typically comprises pattern bits indicating a pattern of the first data sequence and location bits indicating a start location of the first data sequence.
