$WBT Weebit Nano Qualifies Its ReRAM Module for Automotive Grade Temperature

Extending Qualification to Higher Temperatures for a Broad Range of Applications
Weebit Nano Ltd (ASX:WBT), a leading developer of advanced memory technologies for the global semiconductor industry, has achieved a significant milestone in its development. The company announced that it has successfully qualified its Resistive Random-Access Memory (ReRAM) module to operate at temperatures up to 125 degrees Celsius, meeting the strict requirements for automotive grade 1 Non-Volatile Memories (NVMs).

Suitability for Automotive and Industrial Applications

The qualification of Weebit ReRAM at these high temperatures demonstrates its suitability for use in microcontrollers and other automotive components, as well as high-temperature industrial and IoT applications. The testing was conducted using Weebit's demo chips, which were manufactured in collaboration with its R&D partner, CEA-Leti, and adhered to the well-known JEDEC industry standards for NVMs.

Rigorous Qualification Process

The qualification process involved rigorous testing of several silicon dies blindly selected from three independent wafer lots. While most chips for ... consumer and industrial applications need to be qualified for up to 10 years at temperatures ranging from zero to 85 degrees Celsius, advanced automotive components have much higher temperature requirements for a duration of 10 years or longer, without any failures.

Weebit's ReRAM modules successfully passed the entire set of qualification tests at 125 degrees Celsius for 10 years retention, showcasing the quality, repeatability, and high-temperature reliability of Weebit's embedded ReRAM IP.

Future Prospects and Industry Impact

Coby Hanoch, CEO of Weebit Nano, emphasised that this achievement is part of an ongoing process aimed at extending the qualification of the ReRAM technology to even higher temperatures and endurance levels. The company is witnessing increased interest in its ReRAM modules for automotive and industrial applications. Hanoch highlights that ReRAM technology offers several advantages over other emerging NVMs, including high temperature performance, low complexity, cost-effectiveness, and tolerance to radiation and electromagnetic interference.

According to Simone Bertolazzi, Principal Technology & Market Analyst of Memory at Yole Intelligence, embedded ReRAM is considered a promising candidate for automotive applications. It demonstrates better performance metrics than flash, such as programming time, endurance, and power consumption. With the involvement of major foundries and leading automotive MCU suppliers, the volume of embedded ReRAM wafers is expected to rise significantly in the coming years.

Weebit Nano is at the forefront of pioneering resistive memory technology, offering chip designers the opportunity to incorporate ReRAM modules to create automotive circuits with improved performance, power efficiency, and cost-effectiveness.

Weebit Nano will continue to extend the qualification of its ReRAM modules to higher temperature and endurance levels in collaboration with CEA-Leti and SkyWater Technology, further solidifying its position in the global semiconductor industry.
