This achievement confirms the quality and reliability of Weebit’s embedded ReRAM non-volatile memory (NVM) technology for high-temperature automotive applications.
The Automotive Electronics Council (AEC) was originally established by Chrysler, Ford, and GM for the purpose of establishing common part-qualification and quality-system standards, and since then many key players in the automotive industry have joined. AEC-Q100 is the standard automotive stress test qualification for integrated circuits (ICs).
The Weebit ReRAM module was qualified according to the AEC-Q100 standard for Non-Volatile Memory including Program/Erase Endurance, Data Retention and High-Temperature Operating Life (HTOL) qualification tests. The qualification was achieved using a one-transistor one-resistor (1T1R) cell architecture, demonstrating stability at 150°C operation for up to 100K endurance cycles*, including cycling and post-cycling high-temperature data retention.
According to Yole Intelligence, part of Yole Group, the market for semiconductors in the automotive sector will grow from US$52 billion in 2023 to US$97 billion in 2029, with the number of semiconductor devices per car also continuing to grow**. Growth is driven largely by the adoption of more electrification and advanced driver assistance systems (ADAS), leading to the need for more advanced processing and more efficient power management, areas where ReRAM plays a key role.
Coby Hanoch, CEO of Weebit Nano, said: “Full AEC-Q100 qualification is a key requirement for an NVM to be designed into automotive microcontrollers and other components. With this achievement, companies considering embedded NVM will know that the parameters of Weebit ReRAM align with the specifications of automakers, and this will continue to enhance our position in
this domain.
“This qualification also has a much broader impact, beyond automotive, since many industrial and IoT applications, such as downhole tools, combustion engines, oil and gas and others, require high-temperature reliability and extended endurance. Achieving AEC-Q100 qualification influences numerous other applications too, as it gives designers confidence that the technology is very robust
and reliable, even beyond their needs.
“We are confident that this further qualification will generate even stronger interest from potential customers that are seeking memory advancements with temperature reliability and extended endurance requirements"
