I have a ton of this type of ram. SIMM - Wikipedia
It looks like this:
(the top one)
Is it at all possible to use these chips for temporary data storage with the arduino?
Thanks

It's theoretically possible but almost certainly not worth the effort. Those 30-pin SIMMs are typically around 1M*8bits, which means at least 10 address lines and 8 data lines, plus about 4 control signals. You can use fewer than all the bits, and less than all the memory, and shift registers or latches, but you're still looking at having to explicitly move data in and out in software; there is NO way to just attach them and have them show up as extra RAM (for example.)
Woah woah did I ever say I wanted to use them as ram?
Anyways, I have time, And a lot of it. Any pointers on how i can use them?
You need to find something that describes the basics of using Dynamic Memory chips (DRAM); the SIMM is just convenient packaging. Or you might need to start with something that describes using generic RAM at the hardware level (assert chipselect, apply address to address pins, apply or prepare to receive data, assert output enable or write. DRAM adds a step or two because the address bus is multiplexed (apply half at a time, manipulate extra signals), and you have to read each "row" of the chip ever couple of milliseconds or the data decays (that's the "Dynamic" part.) But I don't think I've seen a tutorial like that in quite a long time...

Now I'm curious about what you were going to use them as.
Bookmarks?
Coffee stirrers?
