Weebit Nano qualifies its ReRAM module for automotive grade temperature

Extending qualification to higher temperatures for a broad range of applications

HOD HASHARON, Israel, July 31, 2023 (GLOBE NEWSWIRE) -- Weebit Nano Limited (ASX:WBT), a leading developer of advanced memory technologies for the global semiconductor industry, has fully qualified its Resistive Random-Access Memory (ReRAM) module up to 125 degrees Celsius, the temperature specified for automotive grade 1 Non-Volatile Memories (NVMs). This achievement demonstrates the suitability of Weebit ReRAM for use in microcontrollers and other automotive components, as well as high-temperature industrial and IoT applications.

The qualification, using Weebit’s demo chips manufactured by its R&D partner CEA-Leti, was performed based on well-known JEDEC industry standards for NVMs. These standards impose rigorous testing of many silicon dies blindly selected from three independent wafer lots.

Most chips for consumer and industrial applications need to be qualified for up to 10 years at temperatures between zero and 85 degrees Celsius. Advanced automotive components are much more stringent, requiring qualification at higher temperatures for 10 years or longer, with zero failures. All the Weebit dies successfully passed the entire set of qualification tests at 125 degrees Celsius for 10 years retention, demonstrating the quality and repeatability of Weebit’s embedded ReRAM IP for applications requiring high-temperature reliability.

Coby Hanoch, CEO of Weebit Nano, said: “This achievement is part of an ongoing process through which we are extending the qualification of our ReRAM technology to even higher temperatures, longer retention and higher endurance levels. In our discussions with Tier-1 foundries and semiconductor companies, we’re seeing increased interest in our ReRAM for automotive and industrial applications. Proving the resilience of Weebit ReRAM at such high temperatures will continue to move these discussions forward. We believe ReRAM to be a better choice for automotive and industrial applications compared to other emerging NVMs not only because of its high temperature performance, but also its low complexity, cost effectiveness, and other advantages such as tolerance to radiation and electromagnetic interference.”
