Claims (2)
- 풀-업증폭기의 출력단자와 접속되고, 센싱시 그 풀-업증폭기의 센싱동작에 의해, 프리차지전압 및 프리차지전압보다 높은 전압레벨을 갖는 1쌍의 데이터라인과,풀-다운증폭기의 출력단자에 접속되고, 센싱시 그 풀-다운증폭기의 센싱동작에 의해 프리차지전압 및 프리차지전압보다 낮은 전압레벨을 갖는 1쌍의 데이터라인을 구비하여,프리차지시 상기 두 개의 데이터라인쌍을 이퀄라이징부를 통해 전기적으로 모두 접속시켜 센싱시에 사용했던 전하를 재활용하게 구성된 것을 특징으로 하는 전하재활용 센스앰프.
- 제1항에 있어서, 상기 풀-업증폭기 및 풀-다운증폭기는 한쌍 또는 하나의 출력단자로 이루어진 것을 특징으로 하는 전하재활용 센스앰프.
