SRAM, suitable for frame buffer?

2 posts in this topic

Could I use the 2MB ISSI IS61WV20488BLL SRAM for framebuffering? I'd like to ideally hold more than one layer of 12-bit information at 640x480 with a +30hz refreshrate, I suppose that would require at least 20mhz of ops, can it keep up?

It looks like it is a 10ns part so it should be fine speed wise...

Any reason not to use the SRAM chip used in the Papilio DUO's or the SDRAM in the Pro? There are already examples of using those chips as frame buffers in DesignLab...
