Abstract
본 발명은 더미 셀을 부가하지 않고 기존 프로그램 제어장치 코어(Core)의 주소 및 데이타 버스와 제어 신호들을 이용 간단한 회로를 구성함으로써 내부 ROM의 동작 확인과 원하는 ROM 주소의 프로그램된 데이타값을 출력하는 기능을 갖는 ROM 코드 검증 장치에 관한 것으로, 부가회로 증가에 따라 발생하는 실리콘 영역 손실을 방지하며, 효과적으로 ROM 셀의 동작확인 및 ROM 코드를 검증하는 효과가 있다.The present invention functions to check the operation of the internal ROM and output the programmed data value of the desired ROM address by constructing a simple circuit using the address, data bus and control signals of the existing program controller Core without adding a dummy cell. The present invention relates to a device for verifying a ROM code, which prevents silicon area loss caused by an increase in an additional circuit, and effectively checks the operation of the ROM cell and verifies the ROM code.
