Why they don't research how to make their own RAM and they have to buy it from the common market?
They should GTFO with this crap.
Create barriers to computing for ordinary people while milking businesses for tokens.
People keep saying stuff like this without understanding what it takes to make RAM. It's one of, if not the most, heavily patented things in the world. The second you dip your toes into those waters the lawsuits begin.
If somehow you get around the patent issues, you're now faced with huge research and development costs, fabs to build, processes to sort out and all of that has very high failure rates.
Last time I checked Micron was the largest patent holder in the world and even for them this is a hard area where they are number 3 in the market.
Building a custom-designed ASIC is much easier than producing state of the art memory chips.
There's a reason why Micron and Nvidia are the crown jewels of American technology right now and for the foreseeable future.
