Abstract

본 발명은 DRAM(Dynamic Raandom Access Memory)의 센스앰프 회로에서의 센싱동작의 지연시간을 줄이기 위한 고속 센스 앰프회로에 관한 것으로서, 종래의 DRAM 센스 앰프회로는 기생 캐패시턴스로 인해 비트라인 쌍 BL1,가 선택된 경우에 부하 트랜지스터와 센스앰프군에 의한 센싱시간이 길어져 주앰프가 동작하기전 출력노드의 전압이 충분히 벌어질때까지 기다리는 시간이 길어져 전체 센싱속도가 느려지게 된다.The present invention relates to a high-speed sense amplifier circuit for reducing the delay time of the sensing operation in the sense amplifier circuit of the DRAM (Dynamic Raandom Access Memory), the conventional DRAM sense amplifier circuit is a bit line pair BL 1 , due to parasitic capacitance. When is selected, the sensing time by the load transistor and the sense amplifier group is long, and the waiting time until the voltage of the output node is sufficiently increased before the main amplifier is operated increases the overall sensing speed.

본 발명은 느려지는 센싱시간을 줄이기 위해 센스앰프군의 부하 트랜지스터쌍을 각 센스앰프마다 따로두고 앰프의 출력노드와 주앰프를 분리하는 스위치 트랜지스터를 둠으로써 쎈스앰프 출력노드에 생기하는 기생 캐피시턴스가 센스앰프에 큰부하로써 작용하는 영향을 없애어 센스앰프의 센싱속도가 빨라지게 하여 좀더 개선된 센싱속도를 얻을 수 있게한 고속센스앰프회로를 제공하는 것이다.According to the present invention, a parasitic capacitance generated in a pulse amplifier output node by setting a pair of load transistors of a sense amplifier group for each sense amplifier and a switch transistor that separates an output node and a main amplifier of each amplifier in order to reduce a slow sensing time. It is to provide a high-speed sense amplifier circuit that eliminates the effect of a large load on the sense amplifier to increase the sensing speed of the sense amplifier to obtain a more improved sensing speed.
