Example 4: Connection to Multiple 4-Mbit DRAM Chips (16-Mbyte Mode): Figure 7-13
shows an example of interconnections to two 2CAS 4-Mbit DRAM chips, and the corresponding
address map. Up to four DRAM chips can be connected to area 3 by decoding upper address bits
A
Figure 7-14 shows a setup procedure to be followed by a program for this example. The DRAM
in this example has 9-bit row addresses and 9-bit column addresses. Both chips must be refreshed
simultaneously, so the RFSH pin must be used.
