Ah yes, sorry, I'm aware of that. What I meant in this specific case is that
with 4 2764s right next to each other with a direct signal path between
adjacent address and data pins that has a resistance of 0.5 ohms pin to pin
surely I should be able to put a clip on each (for example) A4 address line
and see the same pulse at all four channels?

is fixed 5v. Also you'd expect that sampling
at four times the clock speed
(they'll both do 25Mhz with 6 channels) then every pulse would be picked up.
No, because the pulse length may be far inferiour to the sample clock
rate. You may also need to capture signal transitions instead of signal
levels (i.e. you record a "pulse" if there was a transition between two
sample clock pulses).
