Abstract

본 발명은 인접한 비트 라인들 간의 용량성 결합으로 인한 프리챠지 속도의 지연을 개선하기 위해 선택된 비트 라인(BL3)을 프리챠지시킬 때 선택된 비트 라인(BL3)에 인접한 적어도 2개의 비트 라인들(BL2,BL4)을 선택된 비트 라인(BL3)과 함께 동시에 프리챠지시킨다. 이로써, 인접한 비트 라인들 간의 결합 용량으로 인해 데이타 감지의 오류 또는 읽기 동작의 지연과 같은 읽기 동작 특성을 저하를 상당히 개선할 수 있게 된다.The present invention provides at least two bit lines BL2, BL3 adjacent to the selected bit line BL3 when precharging the selected bit line BL3 to improve the delay of the precharge rate due to capacitive coupling between adjacent bit lines. BL4 simultaneously with the selected bit line BL3. This makes it possible to significantly reduce the degradation of the read operation characteristics such as the error of data detection or the delay of the read operation due to the coupling capacitance between adjacent bit lines.
