@resistion: The article points out that Samsung is already shipping 3xnm DRAM... ahead of any others. If you are refering to my comment, I was not stating that Elpida was leading on any particular node; I think it's plenty interesting for Elpida if they keep near in time to whoever is leading, particularly if they can do so on a budget.
A common bias regarding Elpida indeed has been that they lag behind their rivals. Can they cost effectively keep things close? It'd be a big deal if they can do so in a business where it's *real* tough on you if you aren't number one.
