RAM used as SSD: Possible?

Seeing as you can load your computer up with gratuitous amounts of RAM, is it possible to use some of it as a virtual SSD?
 
there used to actually be ram drives but they were like ddr 1, it is possible AFAIK but the ram you use doesn't store data long term and requires power 24/7 or it will loose it's memory and idk if it has a degrading curve so the data on it might only last a specific and short period of time. The advantages i see in this idea is that AFAIK RAM chips don't degrade over time and loose performance like an ssd does, even with TRIM on an SSD only has a limited number of read/writes before it dies while ram is re-written billions of times over it's life cycle. Also provided a faster connection it should be much faster, single channel bandwidth is 12.8 and dual channel is 25.6, not sure how fast the RAM itself is but if they made an E-ATX board with the actual mobo being mITX then you could get decent storage at unbelievable speeds. The challenge though is obvious, coordinating the data and finding a way to get it stable, pretty sure a 64 way RAID 0 would be very difficult to do, it'd probably need its own processor on the board to control it and process the data given to it into a single usable string being sent.
 
Standard desktop ram is known as volatile which as Jonny said, constantly requires power to retain information, and is wiped upon power down. I'd say the answer is no.

Ah, okay. Yeah, I knew that, I'd just forgotten it. Well, how about the other way around? could one allocate a certain portion of an SSD to act as RAM?

You could just stick your pagefile on the SSD so it's automatically used as an extension to your system RAM when necessary.

Though SSDs are still orders of magnitude slower than real RAM, plus they tend to have this problem of limited read/write cycles so using it for the pagefile generally isn't recommended.

Definitely. And the results of this just makes me want to max out my RAM and dedicate all but 8GB to a RAM disk to load BF3 on (should be loads faster loads then). BEar in mind this is at 1333 MHz only.

i had a program about 15yrs ago-it was an active user-hidden screenshot
storer- it was intended for school/gov't security etc-like spy stuff-
it would take screen shots and store them in ram-when computer was turned off
it would automatically send them to hdd / when computer was turned on it
would send stored files back to ram-to access file you had to hit certain keys at start up- and then it would leave screen shots on hdd for admin to view
someone shud use this technology the kinda opposite way to store data on ram then send it to hdd when powered off and then back to ram when power on
sorry for rambling it was just a neat program
