Figure 6.32 shows typical interconnections when using two 16-Mbit DRAMs using a
organization, and the corresponding address map. The DRAMs used in this example are of the
11-bit row address
output pin for areas 2 and 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 CS
