Yes, FRAM71 is an add-on memory device designed by Hans Brueggemann that can configured for up to 392K of RAM. Like any soft-configured RAM device, it can be configured as IRAM. Unlike any other RAM device, it can also be configured as ROM. The downside is that there're only about 20 FRAM71's in existence.

I encourage you to get on the waiting list for the next batch. Smile
