A technique is described whereby the addressing architecture of video memories, as used in personal systems with standard video graphics array (VGA) capabilities, is extended so as to allow programs, or devices, to be able to address memory as a single block, with each byte having a unique address. By enabling the addressing to occur with each byte at unique addresses, block transfer and implicit access method support are provided for map-oriented memories.
