DDR was a major step forward in the memory industry, however will we ever see something that can read and write 4 times per clock cycle?

Will we see Quad Data Rate memory?

I don't really know but I would guess no... Single data rate ram only transfered on one side of each wave, while double data rate transfers on both sides. That seems like a logical progression since one side of the cycle was going unused and other hardware could now utilize the extra bandwidth available.
From my understanding of the way things work, I don't see how writing more than twice per clock cycle would be possible.

I would guess that QDR is not going to happen like IMOG has said. On the other hand, the one thing that hasnt happened as of yet is makeing virtural memroy more efficant. Even with 1024 meg of memory installed, I still somehow seem to be subjected to the use of VM. The best advancement that could be made to memory is to make it better at multitasking so that we can eliminate virtural memroy. If that was possible games like HL2 and PlanetSide could possibily play on much lower end desktops. Right now, with the new games that are being realised, you really need to have a top of the line machine. I have a great machine, but I still get some lag, and lots of tweeking to go through constantly.

i wish QDR would happen, but as IMOG said, i dont know how they would want to send 2 signals per clock cycle tbh...
qdr does exist. Micron was the first company to produce it. However samsung is not too far behind. Micron already had working samples of it almost a year ago. Here is samsung/nec's page for development where you can read more about the technologies. www.qdrsram.com

They could do like the P4 bus and use 2 out-of-phase clocks, and transfer twice for each cycle of those...IMOG said:
Via has also been releasing chipsets that it says are compatible wit something it calls QBM (quad band memory).

I'd say: Of course. Technology of man increases every second, why wouldn't memory technology increase aswell? 
Until then: Be happy with your Mushkin lvl 2 DDR

hmm, maybe it can happen now that would be veryyyy cool 
ok, i wont
