Weebit Nano Demo Chips Integrating Embedded ReRAM Module Complete Functional Testing Phase 

Weebit Nano Ltd. confirms demo chips integrating its embedded Resistive Random-Access Memory (ReRAM) module have completed their functional testing phase, a step towards delivering a commercial product.

These are the first available SoCs embedding the firm’s ReRAM array inside its memory module. Potential customers can use the demo chips to test the ReRAM technology ahead of commercial orders and volume production.

After receiving the silicon wafers containing the demo chips from manufacturing in December, the company, together with its development partner CEA-Leti, sliced the wafers into chips, packaged them, and has now completed functional testing of the chips. Testing included programming (set and reset) and reading of the entire ReRAM array using algorithms, ECC and various data manipulations. It also included testing the operation of the complete subsystem comprising all communication interfaces and system peripherals, as well as software running on the RISC-V microcontroller (MCU). The entire chip is performing as expected.

These integrated chips will now be used for characterisation and qualification – the next steps on the firm’s commercialisation path.

Coby Hanoch, CEO, said: “Our team tested the complete demo chip including the full memory array, the advanced features of our memory module, and the entire system, and confirmed that it functions as expected. This is the first time we can see Weebit’s innovative memory technology operating live in a fully functional chip. We are now moving into a new phase of our roadmap during which customers can confidently begin designing Weebit ReRAM into their SoCs. The characterisation process is now underway and will be immediately followed by full qualification.”

Chips based on a similar design are currently being prepared for fabrication in SkyWater Technology’s US production fab. Once the module is qualified at this fab, volume production can commence. The transfer of the company’s embedded ReRAM technology to the fab is progressing on schedule.
