Honored ContributorI don't see why you couldn't put another RAM onto one of the 40-pin connectors, but it would have to be either SRAM or (non-DDR) SDRAM because you're stuck with 3.3v i/o. As far as I know, only SRAM & SDRAM have 3.3v i/io - all the good stuff (DDR, DDR2, DDR3) is < 3.3v.
This was what was so frustrating about the BEMicro SDK - it has the nice 64MB of DDR SDRAM, but uses Mobile DDR SDRAM with little-to-no documentation, so you have to fork out for the ip before you can use it for more than 30 days... Great cheap board, cr@ppy licensing. In terms of other boards, the next-step-up (DE2-115, $299 academic, $595 for hobbyists like me) has 128MB of SDRAM and 2MB of SRAM. If it had a PCIe connector, I'd have bought one by now :) Simon
