News Rambus' HBM2E Memory Controller & PHY Offer Chipmakers Cost-Effective Designs

Isn't Rambus the IP Patent Troll that caused problems in the past for other companies? If so, does this basically mean that using HBM2E is already dead in the water?
 
Rambus doesn't control the patents for hbm2e. They are just making a memory controller. They may try to patent troll the controller, but they don't have the IP portfolio they once had.
