The Weebit ReRAM module in SkyWater Technology’s 130nm CMOS (S130) process has already been qualified at temperatures of up to 125°C – the temperature specified for Grade-1 automotive applications.

Now, as part of firm’s ongoing efforts to demonstrate performance at higher temperatures and higher endurance levels, the company is demonstrating:

  • High endurance: 100,000 cycles (*)

  • High-temperature stability: 150°C lifetime operation, including cycling and retention

Coby Hanoch, CEO, said: “The performance levels we’re achieving align with requirements specified by automotive companies. Demonstrating the resilience of Weebit ReRAM under these conditions will continue to enhance our position in this domain. Our latest results reaffirm the viability of Weebit ReRAM for use in microcontrollers and other automotive components, as well numerous other applications requiring high-temperature reliability and extended endurance. Weebit ReRAM is ideal for these applications, offering advantages including ease of integration, cost effectiveness, power efficiency and tolerance to radiation and electromagnetic fields.”

Amir Regev, VP, quality and reliability, will present the test results during a session at the 8th Electron Devices Technology and Manufacturing Conference (IEEE EDTM 2024), being held in Bangalore, India, March 3-6, 2024.

The company’s ReRAM IP module is available with support in SkyWater’s S130 process design kit. The company is also working closely with DB HiTek to get its ReRAM technology qualified for customer designs.
