Weebit Nano Limited Tapes Out ReRam Demo Chip to SkyWater Foundry

WeebitNano Limited announced it 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 Weebit’s ReRAM technology to a production fab and is a major milestone toward commercialization. The technology will be available on SkyWater’s 130nm CMOS process, which is ideal for applications such as analog, power management, automotive, IoT and medical. SkyWater customers can now use the highly integrated demo chip as the final platform for testing and prototyping ahead of volume production. Weebit’s embedded ReRAM module includes a 256Kb ReRAM array, control logic, decoders, IOs (Input/Output communication elements) and error correcting code (ECC). It is designed with unique patent-pending analog and digital smart circuitry running smart algorithms, thereby significantly enhancing the memory array’s technical parameters. It also supports an extended temperature range, 10 years’ data retention at high temperatures, fast access time, extremely low standby power, and is radiation-hardened (rad-hard) by nature. The demo chip comprises a full sub-system for embedded applications, including the Weebit ReRAM module, a RISC-V microcontroller (MCU), system interfaces, memories and peripherals.

Weebit Nano Limited to Demonstrate Its ReRAM IP Module for the First Time

No independent directors

Following the recent departure of a director, there are no independent directors on the board. The company's board is composed of: No independent directors. 6 non-independent directors. Non-Executive Director Syed Raza was the last director to join the board, commencing their role in 2019. The company's lack of independent directors is a risk according to the Simply Wall St Risk Model.

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

Weebit Nano Limited confirmed demonstration (demo) chips integrating its embedded Resistive Random-Access Memory (ReRAM) module have successfully completed their functional testing phase, a key step towards delivering a commercial product. These are the first available System-on-Chips (SoCs) embedding the Weebit ReRAM array inside its memory module. Potential customers can now use the demo chips to test Weebit’s ReRAM technology ahead of commercial orders and volume production. After receiving the silicon wafers containing the demo chips from manufacturing in December, Weebit, 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 smart algorithms, error correcting code (ECC) and various data manipulations. It also included testing the operation of the complete sub-system 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 highly integrated chips will now be used for characterisation and qualification – the next steps on Weebit’s commercialisation path. 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 SkyWater, volume production can commence. The transfer of Weebit’s embedded ReRAM technology to SkyWater’s production fab is progressing on schedule.
