Abstract (en)

[origin: EP0105724A2] A plurality of color graphic memories (41,51,61) are assigned the same address space, and are connected to a common data bus (X1). It is determined by a separately output memory select data which one of the color graphic memories (41,51,61) is to be written into. In the case of writing the same data into two or more of the color graphic memories (41,51,61) at the same address, the color graphic memories to be written into are selected by the memory select data first and then the same data is written into the selected colour graphic memories in the same write cycle.
