Weebit Nano’s ReRAM IP achieves high temperature qualification in SkyWater Technology’s S130 process

 Weebit Nano (ASX:WBT), a developer of advanced memory technologies for the global semiconductor industry, and SkyWater Technology the trusted technology realization partner, announce that Weebit’s Resistive Random-Access Memory (ReRAM or RRAM) IP module has been fully qualified in SkyWater’s 130nm CMOS (S130) process at temperatures of up to 125 degrees Celsius – the temperature specified for Grade-1 automotive applications.

This qualification, based on a one-transistor one-resistor (1T1R) memory module leverages the previous qualification of Weebit ReRAM IP at these temperatures and is now ready for production tapeout at SkyWater. Such qualification demonstrates the quality and repeatability of Weebit’s embedded ReRAM IP for applications requiring high-temperature reliability. This includes various industrial, IoT, and aerospace products, as well as many automotive components, which must be qualified for operation at 125 degrees Celsius in applications which have lifetimes in excess of 10 years. The qualification was performed to well-known JEDEC industry standards for NVMs.

The S130 process by SkyWater is a silicon proven mixed-signal CMOS platform targeting automotive and industrial applications. With billions of devices in field use already, it features extended temperature capabilities ideal for mixed-signal IoT and edge computing applications. Additionally, it now incorporates embedded NVM, enhancing its suitability for a diverse range of SoC architectures.

Coby Hanoch, CEO of Weebit Nano, said: “SkyWater has customers across the industrial, automotive and aerospace domains who require support for a wide range of temperatures in their products. Weebit ReRAM is ideal for such applications as it performs well at high temperatures and offers added benefits in terms of simplicity, power efficiency, tolerance to electromagnetic fields, and other advantages. We are continuing to progress our discussions with potential customers who we anticipate will adopt Weebit ReRAM in 2024 and beyond.”

John Sakamoto, SkyWater President and COO, said: “SkyWater’s proven CMOS technologies have been used reliably for decades in automotive, aerospace, industrial and medical applications. Customers across these markets are increasingly looking to embed advanced NVM in their chips to add functionality and differentiation. With the recent qualification, we expect to see even more interest in Weebit ReRAM among customers who are looking for NVM that can extend to 125 degrees Celsius. We are delighted to mark another qualification milestone with Weebit.”
