How has 4DS Memory Limited achieved "Further Significant Megabit Success"?
4DS Memory Limited, an Australian-based company, has announced success in further analysis of the Fourth Platform Lot in its quest to produce dynamic random access memory (DRAM)-like performance.
The company has developed a technology called Resistive Random-Access Memory (ReRAM) which has the potential to replace DRAM. In a recent analysis of the Fourth Platform Lot, it demonstrated "Further Significant Megabit Success", which is a strong indication of the technology's promise as a potential replacement for DRAM.
During the analysis, 4DS focused on establishing optimal conditions for the 60nm memory cells in the megabit array. The company announced that it has outperformed DRAM write speeds, with a write speed of 9. 5 nanoseconds. It has significantly increased the endurance of megabit arrays in excess of 3 billion cycles, verified equivalent DRAM read speeds, and has persistent memory with variable and tuneable retention.

The company had previously announced the use of newly developed process improvements aided by the Stanford Nanofabrication Facility to validate the transferability of the technology from fab-to-fab and optimize the technology. The Fourth Platform Lot demonstrated fully functioning megabit arrays with 60nm memory cells, access transistors, and write circuitry, with a retention that is tuneable and persistent. Previous analysis had demonstrated endurance well in excess of 2 billion cycles.
Further enhancements expected
Despite these promising developments, the upper limit of endurance remains unknown, and the company will continue its analysis to test the upper limits of endurance and read/write characteristics for future enhancements to the platform. With these significant breakthroughs and a strong financial balance sheet, the company is well-positioned to position itself in the memory space targeting technology that can be closer to DRAM.
David McAuliffe's appointment as Executive Chairman is another noteworthy announcement from the company. In a statement, he referred to the further developments as a "significant milestone for the Company" and pledged to undertake further analyses to enhance the Platform.
