6.5.12 Examples of Use
Examples of DRAM connection and program setup procedures are shown below. When the
DRAM interface is used, check the DRAM device characteristics and choose the most appropriate
method of use for that device.
Connection Examples
• Figure 6.31 shows typical interconnections when using two 2-CAS type 16-Mbit DRAMs
using a × 16-bit organization, and the corresponding address map. The DRAMs used in this
example are of the 10-bit row address × 10-bit column address type. Up to four DRAMs can
be connected by designating areas 2 to 5 as DRAM space.
