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)
But who knows. Their unified memory architecture across core types already puts them in a different design space. Maybe that design space leads them to further opportunities for memory architecture differentiation.
I could see them (1) taking the two processing chips that make up an Ultra in coming generations, (2) fabbed with logic on top, and power distributed on the back side, as Intel is going for, and (3) sandwiching the logic sides around a layer of unified RAM, with (4) massive optical linking distributed across the surfaces, resulting in (5) unbelievable bandwidths and parallelism we couldn't dream of today.
And then, (6) announcing it at WWDC 2029 and (7) taking my money 5 minutes after the midnight when pre-order's start.
Apple knows better than to buy a pile of incompetent smugs. Intel was rock bottom before Europe determined it was a “strategic move”[1] to buy factories in Europe from the only manufacturer that hasn’t innovated since 20 years, quickly followed by the US. In both cases, governments aren’t the most savvy spenders.
[1] A “strategic” expense is named like this when you can’t justify it by any rational means.

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.
"Decades" seems excessive
I would suspect at Apple scale it makes sense.
Apple has started making a lot of different things in house, its only a matter of time imo.
I doubt they want to make a commodity.

(5.5) cool the whole thing in a way nobody else manages because of their vertical integration.
in a sense that's exactly what cartel wants - to lure out investments that will get squashed into uselessness by supply flood that will follow
The key is Apple can be their own customer and just not care anymore.
It’ll probably only be worth it if it enables something “new” like more bigger Ultra chips or something.
and that's part of risk management, on both sides
does Apple have enough of a design moat to overcome eventual overprice compared to competitors when "outisde" production is 2,4,10x cheaper
does Apple have enough of income/savings to maintain internal production capacity if it decides to switch back to outside sources
or can Apple acquire enough fab competence to negate internal/external price difference
we'll see how it plays out
Who is the cartel?
SK Hynix, Samsung and Micron?
They should be banned.
This is probably the natural conclusion but it will take some time to get there
Or they can go to existing manufacturers with bags of money and have the experts build them their own production lines, and secure the supply.
they blew it! They could have bought Intel for cheap and made memory AND CPUs!
