And SDRAM and EDRAM...  ( No, I don't mean EDO ! )

Just about all these technologies are fabricated for use over a range of
speeds. EDO probably comes faster than 60 ns these days but I doubt
anybody has made any slower than 70 ns. It is a 'go faster' variant
after all.

No. The quickest is probably EDRAM. This is about 10% more expensive and
much faster. A kind of cache in the simm technology with access times
down to less than 15 ns for consecutive accesses.

This is not exactly main stream, but you can buy these systems off the
shelf.
