Weebit Nano ReRAM IP now available in SkyWater Technology’s S130 process

2 mins read

Weebit Nano and SkyWater Technology have announced the availability of Weebit’s resistive RAM (ReRAM) IP in SkyWater’s 130nm CMOS (S130) process.

SkyWater customers will now be able to integrate Weebit’s non-volatile memory (NVM) into their system-on-chip (SoC) designs. Weebit has said that it will be demonstrating its S130 ReRAM IP module at Embedded World 2023, running from March 14-16, 2023.

Weebit, a specialist in advanced memory technologies, said that its ReRAM will enable semiconductor designs to be faster, lower cost, more reliable and more energy efficient than those using flash or other emerging NVMs. Weebit ReRAM technology in S130 is an ultra-low power, radiation tolerant and secure NVM that companies can use in developing highly integrated SoCs for applications across analogue/mixed-signal, IoT, automotive, industrial, and medical.

Demo chips produced by SkyWater integrating Weebit’s ReRAM module were recently received from manufacturing and proven fully functional. These chips are currently under qualification, and are being used for customer demonstrations, testing and prototyping.

Commenting Coby Hanoch, CEO of Weebit Nano, said, “Our valuable partnership with SkyWater has enabled us to bring this first Weebit ReRAM product to market. Our teams have worked tirelessly towards commercialisation of the technology, with our ReRAM IP now commercially available for customers to design their products in SkyWater’s US foundry. ReRAM is no longer the technology of the future – it is here now. We are now working with a number of potential customers to map the technology’s advantages to their specific design requirements.”

“Weebit ReRAM offers our customers a differentiated NVM solution they can use in developing highly integrated products at ultra-low power,” said Steve Kosier, CTO of SkyWater. He continued, “Weebit’s technology has excellent reliability even at high temperatures, and is tolerant to radiation and electro-magnetic fields, making it a great fit for many of our customers’ demanding target markets. The IP will be supported in our process design kit, allowing customers to integrate Weebit ReRAM into their designs. We look forward to partnering with our customers as they use this innovative NVM to embed more intelligence and capabilities in their next-generation products.”

Highlights of Weebit ReRAM IP:

  • High write cycle endurance, up to 100K cycles, supporting applications with recurring memory updates,
  • Supports 10 years’ data retention at high temperatures,
  • Ultra-low power consumption, including down to zero standby power,
  • Fast access time for quick bootup/instant-on capability,
  • Fast programming time with byte addressability,
  • Tolerant to ionizing radiation and electromagnetic interference (EMI), and
  • Inherently secure technology, deeply embedded between two metal layers.

Full qualification of the Weebit ReRAM memory module in SkyWater’s US production fab is expected to be completed in the first half of 2023.
