Samsung is one of the Big Three memory manufacturers. Samsung’s phone division had some news articles talkimg about how they couldn’t get Samsung’s memory division to give them privileged access, even.

(Though for context, about two years earlier when there was a glut of memory and Samsung’s memory division was losing money, they apparently went to the Samsung phone division and tried to get them to buy a bunch of the excess, which I suppose would have meant putting more memory in their phones than would have been optimal. The phone division told them no way.)
