• Figure 6.31 shows typical interconnections when using two 4-Mbit DRAMs, and the
Figure 6.31 Interconnections and Address Map for 2-CAS 4-Mbit DRAMs with × 16-Bit
corresponding address map. The DRAMs used in this example are of the 9-bit row address ×
9-bit column address type. In this example, upper address decoding allows multiple DRAMs to
be connected to a single area. The RFSH pin is used in this case, since both DRAMs must be
refreshed simultaneously. However, note that RAS down mode cannot be used in this
interconnection example.
