Claims (2)
- 데이터용 핀을 통해 데이터를 입력받아, 제어용 핀을 통해 입력되는 각종 제어신호에 따라 동작하여, 해당하는 신호를 생성하여 상기 데이터용 핀을 통해 출력하는 컨트롤러용 집적회로에 있어서, 상기 데이터용 핀을 통해 입력되는 데이터의 값이 테스트를 위한 상태를 나타내는 경우를 판단하여, 집적회로를 테스트 상태로 전환시켜주는 상태 판단수단을 포함하여 이루어져 있는 것을 특징으로 하는 별도의 테스트용 핀 없이 성능을 테스트할 수 있는 집적회로.
- 제1항에 있어서, 상기 상태 판단수단은 데이터용 핀을 통해 입력되는 신호의 하위 비트에 특정한 신호가 입력되면 테스트를 위한 상태로 판단하는 것을 특징으로 하는 별도의 테스트용 핀 없이 성능을 테스트할 수 있는 집적회로.
