1. eliminate the method that coupling is crosstalked between bit line for one kind, it is characterized in that adopting full bit line clamper structure and cooperate corresponding time sequence to eliminate causing be coupled between the bit line of error code and crosstalk, or lane place line clamper shielding construction and cooperate the corresponding time sequence elimination to cause to be coupled between the bit line of error code and crosstalk when adopting;

  • Wherein;

    Described full bit line clamper structure, other bit lines in a read cycle except selected bit line all are clamped at a fixed level;

    Lane place line clamper shielding construction when described is divided into two or more not overlapping sub-time periods with a read cycle, in some sub-time periods, have only selected the reading of non-conterminous bit line energy, and other bit lines all is clamped at fixed level.
