Honored ContributorSDRAM Interface to SO-DIMM?
I'm planning a NiosII design and we need a pile of RAM but don't need the high bandwidth of SRAM. It's hard to find SDRAM chips in stock, given their commodity nature, and so I was looki...

Honored ContributorI think you'll be able to get SDRAM SO-DIMM's for a very long time. Common sense says they would be available much longer than any single chip you'd pick. Our board that's been shipping for 4+ years (design started 5+ years ago) still uses 72 pin EDO SIMMs.
It's not that much trouble to get them and they are $5-$10 for 16-32MB stick. I agree that DDR would be an even better choice if you can develop the controller. The Twister Cyclone dev board on www.fpga.nl has DDR, but not in a socket. It may come with a controller that is close? I know I'd like to have either one for a future board spin http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif Ken
