Abstract: 본 발명의 목적은 플래시 메모리를 클록에 동기한 버스트 독출 모드와 클록에 비동기인 통상 독출 모드에서 동작 가능하게 하는 것이다. 
     본 발명은 플래시 메모리 등의 비휘발성 메모리 회로에 있어서, 클록에 동기한 버스트 독출 모드와 클록에 비동기인 통상 독출 모드의 양쪽의 독출 동작을 가능하게 한 구성으로서, 전원 투입에 응답하여 통상 독출 모드로 설정되고, 버스트 독출을 지령하는 제어 신호에 응답하여 버스트 독출 모드로 설정되는 것을 특징으로 한다.  이 때문에, 메모리 회로는 내부에 버스트 모드 전환 회로를 가지며, 이 버스트 모드 전환 회로가 전원 투입에 응답하여 출력 회로를 통상 독출 모드로 설정하고, 전원 투입 후에는 클록에 비동기인 독출 동작을 가능하게 한다.  또한, 시스템측에서 공급되는 버스트 모드 제어 신호에 응답하여, 버스트 모드 전환 회로가 출력 회로를 버스트 출력 모드로 설정한다.  따라서, 시스템측은 종래의 메인 메모리에 액세스하는 것과 동일한 환경하에서, 비휘발성 메모리 회로로의 버스트 독출을 실행할 수 있다.
