Rambus has acquired privately-held Unity Semiconductor, a memory technology company for an aggregate of $35 million in cash. As part of this acquisition, the Unity team members have joined Rambus to continue developing innovations and solutions for next-generation non-volatile memory.

This acquisition will expand the breadth of Rambus’ memory technologies and will open up new markets for licensing. Unity has developed a novel solid state memory technology intended to replace NAND in the growing non-volatile memory market.

With nine years of development history, Unity’s memory technology, CMOx, has been designed to accelerate the commercialization of the Terabit generation of non-volatile memories. Devices using CMOx cell technology are expected to achieve higher density, faster performance, lower manufacturing costs and greater data reliability than NAND Flash.

Annual revenue 2011 of Rambus was $312.4 million; the net loss was $43.1 million.
