Abstract
PURPOSE: To make it possible to access display data consisting of the prescribed number of bits by one operation by controlling the bit access of two memory planes by a selection means. CONSTITUTION: A decoder 5 outputs one of memory selection signals R, G, B, I in accordance with an address based upon a mode specification signal outputted from a processor, a decoder 12 outputs a bit selection signal in accordance with the selection signal and a decoder 13 similarly outputs a gate signal. Thereby an OR circuit to which one of gate signals X3 to X0 or Y3 to Y0 is inputted out of plural OR circuits 21 to 24 outputs the signal R, G, B, or I to a corresponding memory plane out of plural memory planes 1 to 4. Consequently one of the memory planes 1 to 4 can be accessed.
