Abstract
A frame memory device for graphics includes a frame memory made up of a pair of memories and a memory controller for controlling the frame memory and is able to smoothly access the frame memory and is improved in its rendering speed. Each memory is logically divided into two banks A and B. Addresses in the thus divided bank are arranged in a checker pattern. The memory controller simultaneously selects bank addresses horizontally and vertically adjacent to a bank address currently being accessed.
