alt Hacker News> OpenAI isn’t even bothering to buy finished memory modules! No, their deals are unprecedentedly only for raw wafers — uncut, unfinished, and not even allocated to a specific DRAM standard yet. It’s not even clear if they have decided yet on how or when they will finish them into RAM sticks or HBM! Right now it seems like these wafers will just be stockpiled in warehouses
That is not "totally normal".

It seems not normal (in the sense that it is obviously quite weird to but like half of the world’s RAM supply). But I wonder if they are also just not ready to announce what they are doing with it?
I mean with that many wafers, I guess it is possible that they’d be doing something pretty custom with the things…
It's not really that different from Apple reserving wafer starts on TSMC's next node and so on. It's just that this kind of capacity requirement has rarely shown up in DRAM before. Vendors prefer this kind of capacity reservation over a more variable finished product requirement. It allows them to know that they can build at the bottleneck rather than having to start up more capacity and then having that lie idle while everything downstream in DRAM packaging and DIMM production can't actually consume anything.
