Wouldn't surprise me, but Cook did rule out building their own anyway

  > Cook said Apple is willing to deploy its balance sheet to help secure supply and called for all options to be examined, including a review of national security restrictions on Chinese memory suppliers. He ruled out building Apple's own memory factories.

Above all else, any focus to corner supply for them will be focused on the iPhone. It's their cash cow, nearly half of their revenue. They'll sacrifice other products to save the iPhone.
