Ok, lets think this through.


Two chips are now in the "same socket as one".

A command is issued to the "one" chip.

Which chip should respond ?

Both will try to respond, both will be in the same address space.

So, no you can _not_ solder two chips together and expect the device to
know what you have done.

I am not sure why this is not obvious to the casual observer.
