It seems that Ramtron is doing the same thing as MAXIM, offering data 
sheets, but not offering chips in a supply chain.  I have a local rep 
who got me some samples, but it took a couple months and they do not 
stock the memory chips.

I imagine that in a year or so, they will be deeper in the supply 
chain, but right now, I would make sure you can get chips before 
getting too far into design.
