Weebit Nano’s 185% Rally, Onsemi Breakthrough Brings ReRAM Closer to Reality

Weebit Nano’s onsemi Milestone Strengthens Commercial Outlook After 185% Share Price Surge over the past 6 months

Weebit Nano (ASX:WBT) has achieved a significant milestone in its journey toward commercialising its next-generation memory technology, Resistive Random Access Memory (ReRAM). The company has successfully completed the “tape-out” phase — the point where chip designs are finalised and released for manufacturing. This marks the transition from development to early-stage production, as Weebit Nano’s ReRAM technology is now being manufactured at onsemi’s advanced 300mm production facility in the United States for real-world testing and qualification.

For investors, this milestone represents an important early step toward commercialisation. While large-scale production and full market adoption remain ahead, this major step forward with onsemi signals growing traction. Weebit Nano’s FY25 financials revealed that revenue from onsemi contributed approximately AUD 3.6 million, suggesting potential licensing and non-recurring engineering fees of AUD 10–15 million over the qualification period. This underscores the strategic importance of the partnership at this stage of Weebit Nano’s growth.

Confidence in the technology’s readiness was further strengthened earlier this year when the company completed AEC-Q100 qualification at 150°C operation. This rigorous automotive-grade stress test confirms that its ReRAM remains reliable under extreme temperature conditions, making it suitable not only for automotive applications, but also for a wide range of high-performance environments.

A recap of the Weebit Nano story

Weebit Nano is commercialising a next-generation memory technology known as Resistive Random Access Memory (ReRAM). Unlike volatile memory, such as DRAM, ReRAM is non-volatile, meaning it can retain data without constant power. This makes it far more energy-efficient and highly scalable, offering a major advantage as global data demands continue to surge.

Today’s most widely used non-volatile memory technology is NAND flash, but it is reaching its physical and performance limits. As demand for Artificial Intelligence and data-intensive applications accelerates, the industry is pushing for higher storage density. However, NAND flash is struggling to scale below 40 nanometres, which means it can’t scale down with today’s modern computer chips. ReRAM overcomes most of the limitations of flash mameory, enabling faster, more efficient and higher-capacity memory solutions for the next generation of computing, both in standalone storage solutions as well as in embedded memory solutions. The latter is where Weebit Nano is making a lot of progress.

The investor’s takeaway for Weebit Nano 

For growth-focused investors, Weebit Nano presents a compelling long-term opportunity as it addresses a major challenge within the semiconductor industry. Its collaboration with onsemi provides early validation of its technology and demonstrates growing confidence in ReRAM’s commercial potential. If initial prototyping and testing are successful, which we expect we’ll likely know in the first half of 2026, Weebit Nano could begin generating royalty income from onsemi soon after.

The embedded ReRAM market is forecast to reach approximately AUD 957 million by 2027, and we believe Weebit Nano is three to five years ahead of peers such as DorsaVi in terms of commercial readiness. This leadership position, combined with strong industry demand for faster, more efficient memory solutions, offers a clear pathway for long-term growth.

Additionally, Weebit Nano is the only independent provider of ReRAM, i.e. TSMC is the only other provider that offers commercial scale ReRAM to its customers. In other words, Weebit Nano is most likely the go-to ReRAM provider for any chip manufacturer that doesn’t want to be dependent on TSMC!
