4DS Memory Limited

4DS Memory Limited is involved in the ​development of intellectual property pertaining to non - volatile memory storage known as ReRAM which may, assuming development and commercialisation, become a replacement for more traditional Flash memory storage. Established in 2007, 4DS owns 19 US-granted patents for its in-house developed intellectual property. In July 2014, 4DS entered into a joint development agreement (JDA) with HGST, a Western Digital subsidiary to optimize the 4DS Interface Switching ReRAM technology for Storage Class Memory. In November 2017, 4DS entered into a collaboration agreement with imec in Belgium (a) to develop a production-compatible process for the 300mm production tools that memory makers use to fabricate high-density high-volume memories, and (b) to use this production-compatible process and imec’s proven memory platform to build a 4DS megabit memory.
