Zusammenfassung:The present invention relates to a semiconductor memory module. According to an embodiment of the present invention, the semiconductor memory module comprises: a random access memory; a nonvolatile memory; a buffer memory; and a controller configured to perform a read operation on the buffer memory in response to the activation of a control signal. According to a result of the read operation, the controller is further configured to perform a flush operation of storing first data stored in the random access memory in the nonvolatile memory. 본 발명은 반도체 메모리 모듈에 관한 것이다. 본 발명의 실시 예에 따른 반도체 메모리 모듈은 랜덤 액세스 메모리, 불휘발성 메모리, 버퍼 메모리, 그리고 제어 신호의 활성화에 응답하여 버퍼 메모리에 대해 읽기 동작을 수행하도록 구성되는 제어기를 포함한다. 읽기 동작의 결과에 따라, 제어기는 랜덤 액세스 메모리에 저장된 제1 데이터를 불휘발성 메모리에 저장하는 플러시 동작을 수행하도록 더 구성된다.
