This might end up being a strong use case for FeFET FRAM, nonvolatile, high density, and sram fast. In an alternative universe where fram infra was as widespread as flash, memory is fast, cheap, and nonvolatile. It’s just that flash built the infrastructure and climbing that ladder is nearly impossible.
I wouldn't really say SRAM-fast. Maybe DRAM-fast? At least in write speed. But the thing is, you don't need high write speed for this application. And read speed should be the same between flash and FeFETs.
Btw, I've seen some roadmaps in which foundries were heading towards integrating ferroelectrics and floating gates to accelerate switching. The two technologies are not mutually exclusive really, so I think we might see something in the relatively near future. The crazy memory market may help!
