4DS Memory Limited specializes in the advancement of non-volatile semiconductor memory solutions. The company develops Interface Switching ReRAM technology, an innovative resistive random-access memory designed for high-performance applications. This unique area-based switching mechanism delivers exceptional speed, endurance, and adjustable retention, positioning it for crucial roles in artificial intelligence processors, expansive data systems, mobile devices, and cloud data centers as a storage class memory. While historically engaged in a development partnership with imec, a leading nanoelectronics research hub, the company recently announced a strategic review in September 2025, temporarily halting its technology development and concluding its collaborations with both imec and Infineon due to challenges in scaling the technology. Founded in 2007, the firm operates from its headquarters in West Perth, Australia, complemented by research and development facilities in Silicon Valley.
