Load Capacitance of Tri-State Data bus of many SRAMs connected together

Question: What will be the load capacitance of a Tri-State Data bus when more than one SRAM busses are connected together?

 

Answer:

Eventhough only one SRAM will be using the data bus at a time, it will see the load capacitance due to all other data busses from idle SRAMs.

If the pin capaticance of one SRAM's Tri-State Data bus is 15pF and if 5 busses are connected together, then the active driver will see a load of 15 x 5 = 75pF
