Abstract
A graphics display system includes a random access memory arranged with a split serial register and a multiplexer for coupling column of storage cells from the memory array to storage elements of the split serial register. Data stored in either a low half or a high half of the addresses of the memory array may be selectively coupled through the multiplexer to either a low half or a high half of the split serial register. For a tile oriented graphics display operation, this arrangement increases the number of choices of where within the random access memory array to store specific bits of the tile data to be displayed. Data representing a tile can be mapped into a single row of the random access memory array.
