This paper studies the synchronized motions between two complex networks with time delays,which include individual inner synchronization in each network and outer synchronization betweentwo networks. Based on the Lyapunov stability theory and the linear matrix equality (LMI), asynchronous criterion for inner synchronization inside each network is derived. Numerical examplesare given which fit the theoretical analysis. In addition, the involved numerical results show thatthe delays between two networks have little effect on inner synchronization. It is also shown thatsynchronous motions within each network or between two networks are not enhanced if individualintranetwork connections are allowed
