Abstract

본 발명은 비휘발성 메모리를 이용한 재시동 시스템 및 방법에 관한 것으로, 비휘발성 메모리 재시동 시스템은 빠른 재시동을 실현하고, 전원 복구시 장애 발생시점부터 프로그램을 구성할 수 있으며, 한 예로 데이터 베이스시스템의 체크포인터(checkpoint) 기법을 단순화시키거나 사용하지 않아도 된다. 이 기법은 최근 차세대 데이타 베이스 시스템중의 하나로 연구하고있는 메인 메모리 베이스시스템으로 사용 가능하고, 특히 실시간 제어시스템에 적용된다.The present invention relates to a restart system and method using a non-volatile memory, the non-volatile memory restart system realizes a quick restart, and can configure the program from the point of failure when the power is restored, for example check point of the database system There is no need to simplify or use the checkpoint technique. This technique can be used as the main memory base system, which is being studied as one of the next generation database systems, and is especially applied to the real time control system.
