14.5.4.3.8
To allow for very high speeds on the memory bus, the capacitive loading on the local bus must be taken
into consideration as shown in
To implement a system using the hierarchy described earlier for 2 synchronous memory banks, 1 address
latch, and 1 buffer loading the multiplexed address/data bus sees a loading of 4 loads of about 6.5 pF
maximum. For a nominal load, 30 pF can be used.
