Israel-based RRAM developer Weebit Nano announced that it has received the silicon wafers from SkyWater Technology, with embedded Weebit RRAM. The company says this is an important step as its technology is now proven with standard tools and a mature process flow, which makes it easy for customers to dopt its technology.

The silicon SkyWater RRAM-enabled wafers will be sliced into chips, packaged, and then tested and qualified. The chips, which were manufactured in SkyWater’s 130nm CMOS process, will be used for customer demonstrations, testing and prototyping ahead of commercial orders and volume production, allowing customers to confidently start designing SoCs using these ReRAM modules.

Israel-based RRAM developer Weebit Nano demonstrated (together with its partner, CEA-Leti) how its RRAM can provide an exciting new solution for artificial intelligence applications using spiking neural networks, at the Flash Memory Summit:

Neuromorphic computing makes it possible to emulate the brain’s natural operation. Using RRAM, this emulation is much more efficient than today’s simulations, consuming orders of magnitude less power, to allow sophisticated AI at a fraction of the power consumed by today’s systems. This is because the ReRAM (RRAM) cell has physical and functional similarities to a biological brain synapse.

Israel-based RRAM developer Weebit Nano has taped-out demonstration chips integrating its embedded ReRAM module to SkyWater Technology’s foundry. Weebit signed the agreement with SkyWater in September 2021 to transfer its technology to SkyWater's fab.

This is the first tape-out of Weebit's technology to a production fabrication. The technology will be available on SkyWater’s 130nm CMOS process, which is suitable for applications such as analog, power management, automotive, IoT and medical. Weebit says that its chips are designed with unique patent-pending analog and digital smart circuitry running smart algorithms, thereby significantly enhancing the memory array’s technical parameters

Israel-based RRAM developer Weebit Nano announced that together with CEA-Leti iit has demonstrated its first operational crossbar arrays that combine its ReRAM technology with a selector.

Weebit says that that is is a key milestone on the company's path to creating standalone memory chips. The company's RRAM crossbar arrays were developed using a 1S1R (one selector one resistor) architecture to enable the higher density needed for discrete chips. Weebit's arrays can be stacked in 3D layers to deliver higher densities.

Israel-based RRAM developer Weebit Nano announced that it has received from manufacturing the first silicon wafers that integrate its embedded ReRAM module inside complete subsystem demo chips.

These highly integrated chips will be used for testing, characterization and demonstration to potential customers. Weebit also updates that the transfer of the company's embedded ReRAM technology to SkyWater Technology's production fab is progressing on schedule.

Israel-based RRAM developer Weebit Nano raised $25.7 million AUD from four Israeli institutional investment and pension funds. The company also announced a pro rata non-renounceable Entitlement Offer to raise a further $9 million AUD.

The company provided shares at $2.84 AUD per share, which represents a 11.5% discount to the last closing price on 8 November 2021.

Israel-based RRAM developer Weebit Nano announced that together with its partner CEA-Leti, it has demonstrated production-level parameters of its RRAM technology in a 28nm process.

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.

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.

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.

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.
