The company says that it has tested, characterized and measured functional 1 Megabit (Mb) ReRAM arrays in a 28nm process technology on 300mm wafers. The testing demonstrated the robustness of Weebit's ReRAM technology with results showing very good endurance and data retention alongside other production-level quality parameters.

SkyWater to adopt Weebit's RRAM technology it its production fab

Israel-based RRAM developer Weebit Nano has entered into its first commercial deal with US-based semiconductor foundry SkyWater Technologies. The deal includes a technology transfer agreement and a non-exclusive licensing agreement.

Weebit's ReRAM technology will be transferred to SkyWater’s production fab and then qualified for volume production by the end of 2022.

Weebit Nano completed its first embedded RRAM module design and tape-out

Israel-based RRAM developer Weebit Nano announced that it completed the design and the tape-out of its first embedded RRAM module. This integrated test-chip will be used as the final platform for testing and qualification, ahead of customer production.

Weebit says that it has used its patent-pending analog and digital smart circuitry to significantly enhance the array's technical parameters, including speed, retention and endurance. The test chip comprises a full sub-system in which the module is embedded, enabling potential customers to use it as a development and prototyping platform for new products such as low-energy IoT devices.

Weebit Nano developed an ReRAM cell integrated with an OTS selector

Israel-based RRAM developer Weebit Nano announced that it has developed the world's first commercial integration of an oxide-based ReRAM (OxRAM) cell with an ovonic threshold switching (OTS) selector. Weebit says that this is a critical step in the company's commercialization path for the discrete (standalone) memory market (which they hope to achieve by 2024).

The selector is a key element in a memory chip as it enables optimized cell access within the memory array. Weebit developed the technology for the integration together with its development partner CEA-Leti. Weebit says that this technology will broaden its target market beyond embedded memory to include discrete memory technology. In future architectures, the company aims to implement 3D memory stacking and crossbar architectures.

Weebit Nano raises a further $12 million AUD to accelerate its R&D and commercialization

Israel-based RRAM developer Weebit Nano announced it has raised $12 million AUD in its recent placement. The company says that its new funds will enable it to accelerate its commercialisation initiatives, including strengthening its technology, engineering and sales teams and increasing marketing activities in the embedded memory market. A non-underwritten share purchase plan to raise up to $3 million will be offered to eligible shareholders on the same terms as the Placement.

Weebit says it remains on track to achieve its first commercial agreement by mid-2021. Weebit Nano will also be able to accelerate the next phase of standalone memory development across both the technical and commercial aspects to fast track deployment, whilst also developing the next generation of its neuromorphic demo.

Weebit Nano raises $6.6 million AUD in a two-tranche placement

Israel-based RRAM developer Weebit Nano announced it has raised $6.6 million AUD via a two-tranche placement. The funds will be used to complete its memory module development, transfer the technology to a production fab and continue its work on discrete RRAM memory technology.

Weebit says that the placement was priced at a discount of around 22% to its current share price. The company now hopes to accelerate its development work and make up lost time from the COVID-19 shutdown.

Weebit and SiEn Integration Circuits sign agreement for RRAM collaboration

Israel-based SiOx RRAM developer Weebit Nano announced that it has signed a letter-of-intent with China-based SiEn QingDao Integrated Circuits to jointly investigate ways in which Weebit’s
technology can be used in SiEn’s products.

SiEn is a Communal Integrated Device Manufacturer (CIDM) company, which aggregates companies with similar target markets, technologies, production lines and customers to share common manufacturing technology production goals. Weebit hopes that its RRAM technology will
enhance SiEn’s competitive position by adding significant non-volatile memory capability to its future products.

Weebit announces a program to enter the discrete memory market

Israel-based RRAM developer Weebit Nano Announced that it is launching a new program to address the needs of the discrete memory market

Weebit says it is accelerating its entry into the discrete, stand-alone, memory chip market. Weebit says that a key element required for discrete memory chips is the selector, which helps isolate the memory cells so that only the specific cells which should be modified actually are, and all the other cells are disconnected and not impacted.

XTX verifies Weebit's ReRAM memory technology

In August 2019 Israel-based SiOx RRAM developer Weebit Nano announced that it has signed a letter of intent with XTX Technology to investigating ways in which XTX can use Weebit’s technology in its products. Today Weebit announced that XTX verified the technical parameters of Weebit's ReRAM technology and reproduced the results previously achieved with Leti.

Weebit says that this successful external testing with XTX was achieved four months ahead of schedule. The two companies are now investigating ways to integrate Weebit's ReRAM memroy technology into XTX Products.

Weebit Nano raised $3.1 million, aims to transfer to production capacity by end of 2020

Israel-based RRAM developer Weebit Nano Announced that it secured $3.1 million in a combined placement and entitlement offer. The company has also announced that it is progressing in its project to develop a customized ReRAM memory module for its South Korean customer - and aims to to deliver the module in mid-2020.
