An address control circuit for a video memory of a multi-image display system. The circuit includes a video signal source, a video memory for storing the video signal, an address holding circuit for controlling write addresses of the video memory which outputs address values during a video image period and holds address value corresponding to a start instance of a blanking period during the blanking period and a bias generating circuit for positioning address areas of the video memory in which the video signal is stored.
