Next-generation memory developer Weebit Nano (ASX: WBT) has reported the achievement of several significant technical milestones during Q4 FY22 as it progresses towards volume production at SkyWater and first customer orders.
In Q4 FY22, Weebit completed the transfer of its technology to SkyWater’s US production fab, taping-out (released to manufacturing) its first System-on-a-Chip demo chips integrating its embedded ReRAM module.
Commenting on Q4 FY22, Weebit Nano CEO Coby Hanoch said, “These integrated demo chips allow potential customers to evaluate the functionality of our embedded technology, using it to analyse our ReRAM with the goal of integrating it within their new product designs. Technology qualification with SkyWater will commence once we get the wafers back from the fab towards the end of 2022. This will be the final technical step before customers can commence volume production.
“We’ve also started conducting a qualification process on the wafers we received from Leti in their state-of-the-art fab. The initial results are very good, and the qualification results will help us with other fabs.”
The company also publicly demonstrated its ReRAM IP module for the first time at a key industry event, Leti Innovation Days, which showed it being fed live images, retaining this data while powered-off, and then displaying the data separately. The demo also shows how the Direct Program/Erase capability and bit addressability of Weebit ReRAM delivers a significantly faster write speed compared to typical flash memory technology, which needs to access entire data sectors every time it erases/writes.
Weebit’s embedded ReRAM will first be available on SkyWater’s 130nm CMOS process, which is ideal for analog, power management, automotive, IoT and medical applications.
“Weebit is in discussions with several potential customers who need the faster and more energy efficient memory technology and integration flexibility our ReRAM provides. While our embedded ReRAM is suitable for a diverse range of industries and products, we are initially targeting IoT, industrial, aerospace and defense applications. These are domains where our technology has significant competitive advantages over existing flash technology and other emerging non-volatile memories, offering excellent endurance and retention at high temperatures. Robustness, reliability, and longevity in harsh environmental conditions are key requirements for these applications, combined with ultra-low power consumption.”
Weebit is exhibiting at Flash Memory Summit (FMS) 2022 in California next week – the largest global conference for the Non-Volatile Memory ecosystem. The company will be showing both the new demonstration of its demo chip as well as its compelling neuromorphic demo, first shared in 2019. Weebit’s VP Technology Development Amir Regev will also be presenting new test results of its ReRAM memory module.
