organization, and the corresponding address map. The DRAMs used in this example are of the
11-bit row address × 10-bit column address type. The CS2 pin is used as a common RAS
output pin for area 2 and area 3. When the DRAM address space spans a number of contiguous
areas, as in this example, the appropriate setting of bits DRAS2 to DRAS0 enables a single CS
pin to be used as the common RAS output pin for a number of areas, and makes it possible to
directly connect large-capacity DRAM with address space that spans a maximum of four areas.
Any unused CS pins (in this example, the CS3 pin) can be used as input/output ports.
