PURPOSE: A method and a system for performing a dual operating of a computer control is provided to copy the same data from a memory of a master system to a memory of a backup system by connecting memory modules of both systems to each other. CONSTITUTION: A method for performing a dual operating of a computer control comprises the step of: connecting a memory module of a master system to a memory module of a backup system by a communication device; and copying varied information to the memory module of the other system through the connected memory module when a CPU of any one system generates a write signal. A system for performing a dual operating of a computer control comprises a first CPU(11a), a first memory(18a), a second CPU(11b), and a second memory(18b).
