Weebit Nano Ltd. and CEA-Leti are undertaking an environmental initiative that will analyse the environmental impact of Resistive Random-Access Memory (ReRAM) technology compared to other non-volatile memory technologies.
The Life Cycle Assessment (LCA) will estimate the contribution of Weebit’s NVM technology to climate change by quantifying its environmental impact. It will focus on total greenhouse gas (GHG) emissions associated with the uses of mineral, fossil and water resources, energy consumption and gases/chemistry involved with the development, manufacture and operation of the technology.
According to a January 2021 report from the World Economic Forum, 77% of GHG emissions from the electronics industry are attributed to the supply chain, including raw materials mining, manufacture and assembly of electronic components and transportation of the finished product.
Coby Hanoch, CEO, Weebit Nano, said: “With so much of our day to day lives involving devices that run on information and communication technologies [ICT], we are conscious of the rising carbon footprint from these technologies and are looking for opportunities to further reduce our GHG emissions. The choices semiconductor companies make in the design and spec phases, including their choice of memory technologies, play a key role. While AI and IoT have the potential to ultimately create huge efficiencies, there are significant emissions involved in their development and use that we need to be aware of and reduce. While Weebit Nano’s ReRAM accounts for only a fraction of the overall semiconductor ecosystem, as the industry develops more and more devices, many at advanced nodes, every initiative counts. Weebit Nano’s ReRAM is inherently lower power and as a result we believe it has a smaller GHG emission than other NVM technologies. Our ReRAM is strongly positioned to be a leader in NVM for advanced processes where it is no longer technically or economically feasible to embed flash memory, and we are constantly innovating on multiple fronts. The results of the Life Cycle Assessment will support further environmental initiatives, cementing Weebit Nano’s ReRAM as a key memory technology going forward.“
Olivier Faynot, head, silicon component division, CEA-Leti, said: “Every player in the ICT sector has a role to play in reducing the electronics industry’s environmental impact. The NVM assessment we are taking on with Weebit Nano will be valuable in determining main contributors to GHG emissions from the ReRAM supply chain, and will help us examine potential abatement scenarios. This effort is part of an energy efficiency optimisation,proach we are recommending toward reducing the carbon footprint of the ICT industry. We must all work together to pursue solutions across processes, circuits, architectures, software, algorithms, use stage, reuse and recycling.“
