2.5.5.2 DRAM Timing
The selection guides in Figure 2-14 and Figure 2-17 are for primary selection only. Final selection should be based
on the timing in the following tables. For example, the selection guide suggests that four wait states must be used
for 100 MHz operation with Page Mode DRAM. However, consulting the appropriate table, a designer can evaluate
whether fewer wait states might suffice by determining which timing prevents operation at 100 MHz, running the
chip at a slightly lower frequency (for example, 95 MHz), using faster DRAM (if it becomes available), and
manipulating control factors such as capacitive and resistive load to improve overall system performance.
