Abstract
A peripheral device selected with a chip select is mapped onto address space occupied by DRAM without causing internal or external contentions. A first address range is provided for accessing DRAM. A second address range is provided for accessing another device. The second address range is within the first address range. A row address strobe is provided for accesses within both the first and second address ranges but the column address strobe to the DRAM is inhibited when a memory access occurs within the second address range.
