| Zusammenfassung: | A semiconductor system includes a first semiconductor device for outputting a transmission command and a transmission address, inputting/outputting transmission data, and generating an error flag signal when an error bit is included in the transmission data inputted in a read operation, and a second semiconductor device for storing the transfer address in a lookup table circuit when the error flag signal is enabled, comparing the transfer address with a storage address stored in the lookup table circuit when the read operation is performed in response to the transfer command, and outputting the transmission data from the lookup table circuit. It is possible to store the address in the lookup table circuit.
반도체시스템은 전송커맨드 및 전송어드레스를 출력하고, 전송데이터를 입출력하며, 리드동작 시 입력 받은 상기 전송데이터에 에러비트가 포함된 경우 에러플래그신호를 생성하는 제1 반도체장치 및 상기 에러플래그신호가 인에이블되는 경우 룩업테이블회로에 상기 전송어드레스를 저장하고, 상기 전송커맨드에 응답하여 상기 리드동작이 수행되는 경우 상기 전송어드레스와 상기 룩업테이블회로의 내부에 저장된 저장어드레스를 비교하여 상기 룩업테이블회로로부터 상기 전송데이터를 출력하는 제2 반도체장치를 포함한다. |
