And I am now going to answer part of my own question. I got this off of the
It would seem too me that the only thing this would improve is the cost of aQuote:>So, what is EDO-RAM ? Basically, it's the same as normal DRAM in practically all respects, and the

cache miss, not actually ELIMINATING the need for a good cache. Add to which,
without a cache in Write-Back mode, you would continuously have to write
directly back into main memory, forcing the "Output-Enable to be negated" and
negating most of the benefit of being able to make multiple reads in sequence.
Anyone have an opinion on this? I would be very interested to see a machine
running EDO RAM w/ a cache and one without and see a speed comparison.
