Abstract
Description
Claims (1)
- 디램에 전원을 인가하는 입력패드와; 그 입력패드의 출력을 입력받아 정전기와 같은 순간적인 고전압에 의해 생성되는 전류가 디램에 인가되는 것을 방지하는 이에스디부와; 그 이에스디부의 출력을 입력받아 버퍼링하여 디램에 인가하는 입력버퍼로 구성되는 디램의 손상방지회로에 있어서, 상기 이에스디부의 출력을 퓨즈를 통해 플레이트전극에 입력받고 스토리지전극이 접지된 다수의 셀커패시터와; 공정이 완료된 후, 상기 커패시터의 플레이트전극에 전압을 인가하여 특성을 테스트하고, 입력패드와의 전압차를 통해 퓨즈를 절단하는 플레이트테스트패드를 더 포함하여 구성되는 것을 특징으로 하는 디램의 손상방지회로.
