SEQUENCE REPLACEMENT METHOD OF A MEMORY DEVICE, CAPABLE OF REPLACING A SEQUENCE WHICH IS NOT REQUIRED WITH A DIFFERENT SEQUENCE, AND A DEVICE THEREOF

摘要

PURPOSE: A sequence replacement method and a device thereof are provided to improve the reliability of a memory device by replacing a specific sequence which is not required with a different sequence.;CONSTITUTION: A sequence replacing unit(160) comprises a storage part and a sequence substitution circuit. The storage part stores an m number of sequences which are predefined. The sequence substitution circuit receives a first sequence outputted from a host. When the first sequence is the same as one among the m number of sequences, the sequence substitution circuit outputs a substitution sequence to a memory device instead of the first sequence. The substitution sequence includes pattern bits which represent the pattern of the first sequence and location bits which represent the start location of the first sequence.;COPYRIGHT KIPO 2011
