But memory is a quite a specialist manufacturing process, they couldn't just send a design to TSMC and get the same quality and cost. It would take years (decades) to create their own factories that might be able to produce competitive memory. If they use a third party to manufacture with existing skills (Samsung, SK Hynix, Micron etc) they might as well just use their designs too (and buy their chips)

Static RAM needs 6 transistors per cell, an M2 Ultra has 134 billion transistors, do the division and you get... "it doesn't work that way".

    Static RAM is not DRAM.

    You certainly could do try a 20bn cell SRAM, in 155mm^2, if you could handle the routing, but the power consumption might surprise you.
