I think commoditize means "make cheaper, maybe by commoditizing" in this context.
Memory is and was commoditized. It just got more expensive.
They can choose how strong they commoditize their complement: perhaps buying up and expanding operations of RAM manufacture (an investment indeed, or a revenue insurance if a GPU competitor springs up), or more expensive buying up IP and licensing IP below market prices to novel RAM factories in friendly nations perhaps with exclusive priority or agreed prices for RAM at specified volumes etc., or even more expensive buying up IP and putting in public domain. The most optimal depth of commoditization would have to be calculated by such a GPU manufacturer.
