ASX-listed semiconductor company Weebit Nano (WBT) has successfully completed its technology stabilisation process and is now ready to transfer its silicon oxide ReRAM memory technology to a production fab.
Conducted with its research partner Leti in France, the final stage in the stabilisation process successfully reduced the cell to cell and die to die non-uniformity of Weebit’s ReRAM, further increased the level of functional cells, and ensured batch-to-batch repeatability.
These improvements to Weebit’s next-generation memory technology are an important milestone on the path to productisation and commercialisation, creating a solid foundation for its next development steps, including the module IP design for the embedded market, standalone memory for mass storage, and production in a foundry.
The final stabilisation phase continued the significant improvement of Weebit’s memory functionality, exceeding expectations and bringing the level of functional cells to over 99%, a key requirement when moving to production. In addition, optimised integration showed excellent wafer to wafer reproducibility for various programming conditions, which means that different memory cells in different areas of a wafer and across different wafers in the batch present the same behaviour (similar resistivity response to various voltage levels).
Coby Hanoch, CEO of Weebit Nano, said: “The successful completion of the stabilisation process follows four years of extensive research and development by the joint Weebit and Leti engineering teams, which has created a unique and highly competitive ReRAM technology. Our close collaboration with Leti will continue, as we constantly strive to improve and further optimise the technical parameters of our silicon oxide ReRAM.
“In parallel to completing the stabilisation process which has reinforced the capabilities of our technology, we are moving closer to commercialisation, engaging in discussions with a production partner and working towards transferring our IP and achieving technology qualification in the partner’s fab.”
