The problem for Rambus is if it tries to hold these companies to the royalties, it risks undermining its relationship with them, and at the moment Rambus needs all the friends it can find in the DRAM industry.

But even if the contracts hold, it's unlikely Rambus will add to those deals, ending yet another Rambus dream. Read our conflicts and disclosure policy . Order reprints of TSC articles.
