Weebit Nano Demos Chips Integrating ReRAM Module to SkyWater Technology Foundry

Weebit Nano Ltd. has taped-out (released to manufacturing) demonstration chips integrating its embedded Resistive Random-Access Memory (ReRAM) module to SkyWater Technology’s foundry.

This is the first tape-out of the company’s ReRAM technology to a production fab and is a milestone toward commercialization. The technology will be available on SkyWater’s 130nm CMOS process, which is for applications such as analog, power management, automotive, IoT and medical. SkyWater customers can use the integrated demo chip as the final platform for testing and prototyping ahead of volume production.

Coby Hanoch, CEO, Weebit Nano, said: “We’ve developed a close and efficient partnership with SkyWater, enabling us to meet our milestones, and bringing us ever closer to volume production. This successful tape-out concludes the technology transfer to SkyWater’s US production fab, and once the chips are back from the fab, we will proceed with technology qualification. We’re in discussions with early-adopter customers looking to leverage our faster, more efficient memory technology to increase their competitiveness in the market.”

Thomas Sonderman, president and CEO, SkyWater, said: “We plan to offer Weebit ReRAM as part of our growing portfolio of silicon-proven design IP. Weebit ReRAM is a rich building block our customers can leverage to create innovative, highly differentiated SoC designs.  Given the technology’s ultra-low power consumption and integration flexibility, we are already seeing enthusiastic interest from customers in areas such as IoT, power management and mixed-signal designs.” 

The embedded ReRAM module includes a 256Kb ReRAM array, control logic, decoders, IOs elements, and ECC. It is designed with patent-pending analog and digital smart circuitry running smart algorithms, thereby enhancing the memory array’s technical parameters.  It also supports an extended temperature range, 10-years’ data retention at high temperatures, fast access time, low standby power, and is radiation-hardened (rad-hard) by nature.

The demo chip comprises a full subsystem for embedded applications, including the firm’s ReRAM module, a RISC-V microcontroller (MCU), system interfaces, memories and peripherals.
