A real time auto-backup memory system comprises a CPU; a system transmission interface connected to the CPU; a bridge control unit connected to the system transmission interface; a system memory disk connecting port connected to the bridge control unit; a backup memory disk connecting port connected to the bridge control unit; a system memory disk connected to the system memory disk connecting port; a backup memory disk connected to the backup memory disk connecting port. The bridge control unit serves for detecting data difference between a system memory disk and a backup memory disk. As the central processing unit is started, the bridge control unit will direct record works to the system memory disk. The bridge control unit controls the system memory disk to backup data in time. The data in the system memory disk is recorded to the backup memory disk, while the CPU does its work without interference.
