RRAM-Info is a news hub and knowledge center for Resistive RAM technologies.
Resistive RAM is a non-volatile computer memory that uses materials that change their resistance - or memristors. RRAM is still in its early stages, but it may enable fast, efficient and small memory chips
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.
CrossBar says that its partners are now starting to use its RRAM memory technology for few-time programmable (FTP) and one-time-programmable (OTP) NVM applications. This is in addition to CrossBar's "traditional" MTP non-volatile memory and PUF security applications.
CrossBar says that this new applications demand can be met with its current technology, but the company also offers to optimize its RRAM for FTP and OTP applications, which will significantly increase memory density and reduce the cost.
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.
RRAM developer CrossBar announced (in July 2021) a new application of its RRAM technology for use as a physical unclonable function (PUF) in order to generate cryptographic keys in secure computing applications.
CrossBar's RRAM has been historically utilized as non-volatile semiconductor memory, but it is now being introduced for use in hardware security. The company says its solution can enable a more secure and cost-effective class of devices and systems.
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.
Researchers from Kyushu University and the National Taiwan Normal University developed a new RRAM device, readable through both electrical and optical methods. The device is based on perovskite quantum dots that enable to simultaneously store and visually transmit data.
By integrating a light-emitting electrochemical cell with a resistive random-access memory that are both based on perovskite, the team achieved parallel and synchronous reading of data both electrically and optically in a ‘light-emitting memory.’
The project NEUROTEC (“Neuro-inspired artificial intelligence technologies for the electronics of the future”) was launched in November 2019 to develop innovative "Beyond von Neumann" concepts for highly energy-efficient devices. The two-year project shows the great potential of a future neuromorphic computer.
The project aims to fuse two major technologies - machine learning and artificial neural networks (ANNs) and memristive materials and devices - especially redox-based RRAM and phase change memories (PCM). The project's mandate is to develop a full-range of basic technologies ranging from dedicated material deposition technologies, integration technologies, measurement technologies, the development of simulation and modelling tools, up to the design and realization of novel AI circuits.
