Claims (2)
- 정상동작일 때에 로우 어드레스 감지신호(RAS 바)와 로우 어드레스 제어신호(RAIP)가 인에이블되어 TTL 입력신호(ATTL)와 이 TTL 입력신 호 (ATTL)를 비교하기 위한 기준전압(VREF)을 각각의 공통노드들(a),(b)에 전달하는 입력신호 및 기준전압 공급부들(1),(2)와, 레프레쉬 동작일 때 인에이블되고 정상 또는 프리챠지동작시 디스에이블되는 로우 어드레스 제어회로(RFIP)에 의해 레플레쉬 타운터 출력들(CNT),(CNT 바) 또는 전원전압들(VCC)을 전달하늘 레플레쉬 신호부들(3),(4)과, 정상 동작일 때 상기 노드들(a),(b)의 TTL 입력신호(ATTL)과 기준전압(VREF)를 비교 증폭하고 레플레쉬 또는 프리챠지 동작시 상기 레플레쉬 카운터 출력들(CNT),(CNT 바) 또는 전원전압들(VCC)를 로우 어드레스 리셋신호(RARD)에 의해 제어되는 전달소자들 (P2),(R4)을 통해 상기 공통 노드들(a),(b)에 전달하는 비교증폭부(5)와, 상기 비교증폭부(5)의 출력들을 래치 출력하는 출력부들(6),(7)을 구비한 로우 어드레스 버프.
- 제1항에 있어서, 상기 레플레쉬 신호부(3),(4)는 전원을 소오스에 연결하고 레플레쉬 제어신호가 게이트에 인가되는 PMOS 트랜지스터(P5),(P6)와, 레플레쉬 카운터 출력(CNT),(CNT 바)이 드레인에 인가되고, 게이트에 레플레쉬 제어신호가 인가되는 NMOS 트랜지스터(N11),(N12)와 구성된 로우 어드레스 버퍼.
