I remember FRAM now that you mention it. There's obviously a lot of promising technologies that die through poor marketing, poor adoption, price, better performing or cheaper alternatives. I see potential in memristors but I think the jury is still out on whether it will see marketplace success. I personally think it has huge upside potential but it sounds like both of us have seen all that be for nothing. I think my previous comment carries more weight though, because it has a pig on it.
