Abstract:
본 발명은 내부전압회로를 구비하는 반도체장치의 회로에 관해 개시한다. 본 발명은 내부전압회로 출력단에 PMOS트랜지스터와 전압 검출기로 구성되는 내부 인가 전압 조절 수단이 연결되어 외부인가 전압 초기에는 상기 내부 인가 조절 수단에 의해 내부 전압이 인가되고 그 이후에는 상기 내부전압회로에 의해 내부 전압이 인가된다. 이렇게 함으로써 상기 내부전압회로에서 바이폴라 접합 트랜지스터의 베이스와 이미터간의 전압강하에 의해 내부 인가 전압이 감소되는 것을 방지할 수 있다. 따라서 상기 외부인가 전압의 인가와 동시에 상기 내부인가 전압이 나타나게 하여 반도체장치의 저 전력 특성이 취약해지는 것을 방지함과 아울러 반도체장치의 고속화도 보장할 수 있다.

Abstract:
In a fuse circuit including programmable fuses in a semiconductor integrated circuit, the fuses store specific information related to the semiconductor integrated circuit, such as redundancy information, wafer lot number, die lot number, and die position on the wafer, etc. The fuse circuit utilizes a plurality of fuses for storing identical bit information. Consequently, in the case where a fuse has not been cut out correctly, the fuse circuit can reduce programming defects, whereby defect generation rates are remarkably decreased.
