You don't say how much memory you're needing

I should have more fully qualified what I was talking about.. I own a
couple FPGA eval boards, and these boards have (mostly) some type of
DRAM memory(xilinx has DDR, and altera has single data rate SDRAM) which
gives you a fair bit of memory. There are a few boards that have SRAM,
but there is often very little of it. With the FGPAs I'm using, they
have integrated fast memory made up of M9Ks or Block Rams. They present
a very easy to use interface.
While I could plonk an SRAM on a connected protoboard, it would eat up
all my spare GPIOs and then I'd have memory but nothing to do with it. :)
I've never used sram, but all the associated HDL I've seen associated
with using one is very easy and simple.
I'd love if my boards came with 8mb or more of SRAM. :)
For this particular flash-in-the-pan idea, I need a VGA frame buffer.
I've got a similar idea for a scan converter which would take low-res
digital video in and spit out higher-res and higher refresh rates.
Thanks
