Intel could re-enter the memory business if it really wanted to. Compared with 18A, DRAM is arguably much less complex from an execution standpoint—and it could potentially bring 70%+ margins while putting idle fabs to use.So the next inflection point (with respect to supply) will be 3D DRAM?
But is 70% floor margin will exceed intel's hay day margin of low 60% when they had total domination.
I think they can hold that for the next few years because new fabs take a long time to build and since everyone underestimated this AI wave, there is now an air pocket. More importantly, people are not fully convinced that this surge will sustain (hence the SCAs, right?) so they will only cautiously invest capital.
But if this AI thing proves to be structural, then 70% GM floor will not hold; JVs or Chinese, there will be many more players.
The main hurdle would be IP, but even that could be addressed through licensing deals with players like Nanya or YMTC.
