Overview
Weebit Nano is an Israeli semiconductor intellectual-property company focused on resistive random-access memory, commonly abbreviated ReRAM or RRAM. Unlike volatile memory, ReRAM is designed to retain stored information when electrical power is removed. Weebit’s business is centered on developing, productizing, qualifying, and licensing ReRAM intellectual property to semiconductor manufacturers, foundries, and chip designers rather than selling finished consumer electronics or packaged memory products under its own retail brand. The company was established in Israel in 2015 with roots in research and patent work associated with Professor James Tour of Rice University. Its objective was to turn emerging ReRAM research into a manufacturable semiconductor technology. In 2016, Weebit Nano merged with Australian company Radar Iron, after which the combined business adopted the Weebit Nano name and began trading on the Australian Securities Exchange under the symbol WBT. The company has retained an international operating model, combining Israeli corporate and engineering activity with research and commercialization relationships in France, the United States, Australia, China, India, Italy, South Korea, and other semiconductor markets. Weebit’s principal technology is an oxide-based form of ReRAM, generally described as OxRAM. The memory cells are designed to be compatible with standard CMOS semiconductor manufacturing and are integrated into the back-end-of-line portion of a chip fabrication process. This integration approach is intended to reduce disruption to a foundry’s transistor-manufacturing flow and make the technology suitable for incorporation into existing process platforms. The company has worked with research institute CEA-Leti on technology development, process nodes, memory arrays, selectors, and embedded memory modules. Its work has included both bulk CMOS and fully depleted silicon-on-insulator, or FD-SOI, platforms. The initial commercialization strategy has concentrated on embedded ReRAM: memory arrays and supporting circuitry integrated directly into systems-on-chip designs. Such embedded non-volatile memory can be used for configuration data, security functions, firmware, code storage, calibration information, and other applications where persistence, endurance, performance, and power efficiency are important. Weebit has also described longer-term opportunities in discrete ReRAM devices, in which memory is supplied in an individual chip package rather than integrated into a larger system-on-chip. Potential application areas include automotive electronics, industrial systems, aerospace and defense equipment, medical devices, Internet of Things endpoints, wearables, smartphones, robotics, autonomous vehicles, communications infrastructure, and artificial-intelligence hardware. The company has additionally investigated the use of ReRAM arrays in neuromorphic computing and analog compute-in-memory architectures, where memory devices can participate directly in computation and potentially reduce data movement and power consumption. A major transition occurred between the company’s research phase and its commercial IP phase. Weebit and CEA-Leti produced increasingly large and capable arrays, demonstrated packaged devices and crossbar structures, and completed technology stabilization and qualification work. In parallel, Weebit established relationships with production foundries. Its partnership with SkyWater Technology led to the first commercially available Weebit ReRAM IP product in SkyWater’s 130 nm CMOS process, initially targeting automotive, defense, and related applications. Subsequent relationships with DB HiTek, GlobalFoundries, onsemi, Efabless, and other ecosystem participants expanded the number of process platforms and design routes through which the technology could be evaluated or adopted. Weebit Nano’s competitive proposition is therefore based on semiconductor IP licensing, process compatibility, non-volatility, endurance, reliability, and the ability to provide memory in process nodes where conventional embedded flash may be difficult or expensive to implement. Its commercial prospects depend on successful qualification, customer design-ins, foundry availability, license agreements, and the ability of its technology to meet demanding automotive, industrial, security, and advanced-computing requirements. The company remains an active public semiconductor technology business, with Coby Hanoch serving as chief executive officer since 2017.
History
Weebit Nano began in Israel in 2015 as a startup intended to commercialize resistive random-access memory technology derived from academic research and patent work associated with Professor James Tour of Rice University. ReRAM is a non-volatile memory technology: it is designed to preserve data without continuous power. The company’s founding objective was not to manufacture consumer memory modules, but to develop semiconductor intellectual property that could be integrated into chips through established foundry processes. In 2016, Weebit Nano merged with the Australian company Radar Iron. The merged organization retained the Weebit Nano name and became listed on the Australian Securities Exchange under the ticker WBT. That transaction provided the company with a public-market structure while it continued developing its technology in Israel and through international research collaborations. A central relationship was formed with CEA-Leti, the French microelectronics research institute. Beginning in 2016, the organizations worked on ReRAM development and later extended their cooperation to technology enhancements, embedded memory modules, and a selector intended to support possible stand-alone memory products. Work with CEA-Leti covered process nodes including 40 nm and 130 nm, while later projects addressed 28 nm and 22 nm FD-SOI technologies. Weebit obtained commercialization rights to relevant joint developments. The company’s technical program progressed through a series of demonstrations. In 2017 it produced working 40 nm silicon-oxide ReRAM cell samples. In 2018 it demonstrated a 1 Mb array fabricated with a 40 nm process and produced the first packaged units containing arrays based on its technology. During the same period, Weebit began exploring applications beyond conventional data storage. Research with the Indian Institute of Technology Delhi, the Polytechnic University of Milan, and the Technion examined ReRAM for neuromorphic computing, artificial intelligence, alternative computing architectures, and lower-power data processing. In 2019, XTX Technology tested Weebit’s ReRAM arrays in its own laboratories and confirmed measurements previously obtained with CEA-Leti. In 2020, Weebit signed a letter of intent with SiEn Integrated Circuits to investigate potential use of the technology in SiEn products. It also demonstrated a spiking neural network using ReRAM. Later that year, Weebit and CEA-Leti completed a technology-stabilization process intended to make the technology transferable to a production fabrication facility. The partnership was extended to include additional ReRAM improvements, further embedded-memory development, and selector work. The move toward production accelerated in 2021. Weebit and CEA-Leti produced, tested, and characterized fully functional 1 Mb ReRAM arrays in a 28 nm FD-SOI process on 300 mm wafers. In September, Weebit and SkyWater Technology announced an agreement under which SkyWater licensed the technology for embedded non-volatile memory in customer designs. Silicon demonstration wafers incorporating the embedded module followed in late 2021. During 2022, Weebit publicly demonstrated its ReRAM IP module, taped out demonstration chips through SkyWater, and received its first production wafers incorporating the technology from the foundry. Other technical developments included demonstrations of crossbar arrays, work toward a multi-megabit ReRAM block for 22 nm FD-SOI, and completion of full technology qualification for a module produced with CEA-Leti. In March 2023, Weebit announced the first commercially available ReRAM IP product, implemented in SkyWater’s 130 nm CMOS process and aimed at automotive, defense, and related applications. The company subsequently reported industrial-temperature qualification, automotive-oriented reliability work, and operation at temperatures relevant to automotive-grade memory. It also reported irradiation studies suggesting that the memory retained data integrity and functionality after high-dose gamma exposure. Weebit expanded its foundry ecosystem in 2023 and 2024. DB HiTek licensed the technology for customer designs in a 130 nm BCD process. Weebit also received wafers integrating its embedded ReRAM in GlobalFoundries’ 22FDX process and prepared a public demonstration of the associated chip. A collaboration with Efabless made the technology available to chipIgnite prototyping customers using SkyWater manufacturing. The company later announced licensing arrangements involving onsemi and described further opportunities in embedded processing semiconductors and advanced computing. Weebit’s current business remains centered on semiconductor IP licensing and technology adoption. Its target markets include automotive, industrial, aerospace, defense, medical, security, IoT, communications, robotics, and artificial-intelligence hardware. The company’s growth depends on converting technology demonstrations and foundry qualifications into customer design wins, production licenses, and recurring IP-related revenue.
