Abstract
Description
US-A-5,487,043에는 비트라인이 신호에 의해 예비충전 전위로 예비충전되는 메모리가 공지되어 있는데, 상기 신호는 동시에 2개의 트랜지스터에 의한 전하 균등화를 실시한다.
Claims (6)
- 기록 가능 메모리 셀(MC);판독 액세스시에는 판독될 데이터를 상기 메모리 셀로부터 상기 메모리의 외부로 전달하고 기록 액세스시에는 기록될 데이터를 상기 메모리의 외부로부터 상기 메모리 셀로 전달하도록 구성된 차동 감지 증폭기;상기 메모리 셀(MC)을 상기 차동 감지 증폭기에 연결하는 한 쌍의 비트라인(BL, /BL); 및판독 액세스시 상기 메모리 셀(MC) 중 하나가 상기 비트라인(BL) 중 하나에 도전 연결되기 전에 상기 비트라인을 여러 단계로 예비충전하기 위한, 상기 비트라인(BL)에 연결된 제어 장치(CTR)를 포함하는 집적 메모리로서,상기 제어 장치(CTR)는 기록 액세스시에, 상기 차동 감지 증폭기(SA)에 의해 상기 비트라인 쌍(BL, /BL)으로 데이터가 전송되기 전에 판독 액세스시에 상기 비트라인(BL, /BL)의 예비충전을 위해 실행된 단계 보다 적은 단계를 수행함을 특징으로 하는 집적 메모리.
- 제 1항에 있어서,판독 액세스시 상기 메모리 셀들의 메모리 셀 내용이 손상되고,상기 차동 감지 증폭기(SA)는 판독 액세스시 상기 메모리 셀(MC)이 상기 비트라인(BL)에 도전 연결된 후에 비트라인 쌍(BL, /BL)에서 나타나는 차동 신호를 증폭시킨 후, 상기 차동 신호를 다시 상기 메모리 셀에 기록하는, 집적 메모리.
- 제 1항에 있어서,상기 제어 장치(CTR)가 판독 액세스시 상기 비트라인(BL, /BL)의 예비충전을 위해, 상기 두 비트라인(BL, /BL)들을 공통 전위로 예비충전시키며, 상기 공통 전위가 기록 액세스시에는 생략되는, 집적 메모리.
- 제 1항 내지 3항 중 어느 한 항에 있어서,상기 제어 장치(CTR)가 판독 액세스시 상기 비트라인(BL, /BL)의 예비충전을 위해 기준 메모리 셀(RC)을 상기 비트라인(BL, /BL)으로 판독하고, 그 뒤에 상기 비트라인간의 전하의 균등화를 수행하며, 이러한 두 개의 동작이 기록 액세스시에는 생략되는, 집적 메모리.
- 제 4항에 있어서,상기 제어 장치(CTR)가 판독 액세스시 상기 비트라인(BL, /BL)의 예비충전을 위해 판독될 상기 메모리 셀(MC)에 연결되는 비트라인(BL)을 방전시키고, 상기 방전이 시간적으로 상기 비트라인들(BL, /BL)간의 전하의 균등화 이후에 이루어지며 기록 액세스시에는 생략되는, 집적 메모리.
- 제 1항 내지 3항 중 어느 한 항에 있어서,판독 액세스시에는 상기 감지 증폭기(SA)의 활성화 이전에 상기 각각의 메모리 셀(MC)이, 상기 비트라인들(BL, /BL) 중 하나에 상기 메모리 셀이 도전 연결됨으로써 판독되고,기록 액세스시에는 상기 감지 증폭기(SA)의 활성화가 먼저 이루어지므로 상기 각각의 메모리 셀(MC)이 상기 비트라인들(BL, /BL) 중 하나에 도전 연결되기 전에 이미 기록될 데이터가 상기 비트라인 쌍(BL, /BL)에 존재하는, 집적 메모리.
