Flex Logix Technologies has closed a $55 million oversubscribed Series D funding round. Mithril Capital Management led the financing with significant participation by existing investors Lux Capital, Eclipse Ventures and the Tate Family Trust.

Privately-held Flex Logix licenses its patented EFLX technology, which enables FPGAs to be embedded into SoCs. This capability dramatically reduces manufacturing and design risk, enhances development flexibility, and accelerates technology roadmaps for a wide array of applications by allowing system designs to be updated after initial manufacture. The company is led by co-founder and CEO Geoff Tate, the founding CEO of IP licensing pioneer Rambus.
