Abstract
본 발명은 반도체 기억소자에 저장된 데이타를 소자 외부로 출력하는 출력버퍼(output buffer)에 관한 것으로 입력 데이타를 일시적으로 저장할 수 있는 데이타 레지스터를 구현하여 상기 입력 데이타를 컬럼 어드레스(column address)의 변화없이 직접 출력할 수 있도록 함으로써 패스터 페이지 모드에서 라이트 동작 이후에 리드 동작이 수행되는 경우에 컬럼 어드레스의 변화 없이 일시적으로 데이타가 저장된 데이타 레지스터에서 데이타를 출력하기 때문에 데이타 출력속도가 빠르고, 또한 결함 데이터가 생기는 것을 방지할 수 있다.The present invention relates to an output buffer for outputting data stored in a semiconductor memory device to an outside of the device. By enabling direct output, when the read operation is performed after the write operation in the fastener page mode, the data output speed is high because the data is temporarily output from the data register where the data is stored without changing the column address. It can be prevented from occurring.
