If I didn't have a sense of humor, I'd say that the speed of the chip (70ns, 
or whatever) refers to the time it takes for the memory to go from a 0 to a 1 
and back again.  Commonly refered to as the ramp time.  Ideally, a chip 
should have a ramp time of 0ns, but that's impossible to achieve.

We would like to see a ramp that looks like this on an O'scope:

   __
__|  |__

but they always look more like:

   __
__/  \__
