4DS Memory Limited, formerly Fitzroy Resources Ltd., is an Australia-based company, which is principally engaged in the development of resistive random access memory (ReRAM), a non-volatile memory. In collaboration with HGST, the Company is developing a non-filamentary ReRAM, which is suitable for gigabyte (GB) silicon storage at smaller geometries. ReRAM is used for next generation storage in mobile and cloud. The Company owns Internet protocol portfolio developed to create high-density gigabyte storage. The Company's Interface Switching ReRAM is suitable for markets that require high-density memory and gigabyte silicon storage. The Company has non-volatile memory solution, which enables higher density memory to operate longer when compared to traditional storage technologies. The Company has its research and development facilities located in Fremont in Silicon Valley, the United States.
