Isn't this where the magnetic memory will prove useful?
No refresh cycles to worry about, and less power draw than static RAM,
or so I gather from the three paragraphs I've read about it. Seems that
it would be ideal for asynchronous processors.
(At the moment the chips are low-capacity, but hey, it'll change.)
The issue isn't refresh. It takes a finite amount of power and time to
initiate the precharge for the bank. Something has to detect charge,
magnetism, or whatever.
Also, 1cm of wire trace is approximate 1pF of capacitance.
Or, that 30cm is approximately 1ns of time.
These are rough estimates, but once you start talking moving charge
around on external traces at high speed, power skyrockets.
