I have added a bit information about using FPM- DRAM's for high-speed
sampling on my homepage. http://www.ebar.dtu.dk/~c888600/dram.htm
The idea is to use the build-in refresh counter, and only clock in
collum addresses (no multiplexer required).

I mensioned it on the PICLIST long time ago, for a LPT-port
framegrabber, but I think that it is possible to use with PIC' based
sampling scopes, high-speed analysers, etc.
