Rambus Inc. ( RMBS ) recently signed a 5-year patent licensing agreement with Nanya Technology Corporation for an undisclosed sum. Per the agreement, Nanya can use Rambus' patented technology for its DRAM products through the second quarter of fiscal 2018. The deal also settles earlier claims regarding its patented innovations. Taiwanese DRAM maker, Nanya is one of the leading providers of memory solutions. It is now one of the top four DRAM companies in the world, the other vendors being Samsung, SK Hynix and Micron Technology Inc. ( MU ). Leveraging Rambus' patent portfolio, Nanya will bring in more innovative technological solutions for end users. Licensing agreements are a recurring revenue source for Rambus, the result of successful monetizing of its patents.
