He noted that Rambus’s “licensing program continues to be strong with the signing of FPGA-leader Xilinx, which expands our footprint beyond DRAM and SoC sectors. We've also seen strong support in our security business within the mobile payments segment and believe we are well positioned to advance this technology further.
