Re:Again...more ram!

Sounds like a good product and I'm sure many people will be interested in it when it's ready. No doubt you'll give us all a "heads-up" when it ready.

I have an SPI flash device fitted at the moment and plan to experiment with compatible FRAMs and SRAMs of the same footprint to try and implement a virtual memory system, for emergency situations!

But this would never be anywhere near as good as a parallel bus arrangement so I think your product will be useful.

It's a shame the devices don't have native bus interfaces though!
