CrossBar announced that its RRAM memory technology is inherently resistant to physical hacking targeting sensitive information and data stored in memory. This could lead to new applications where resistance to reverse engineering and physical attacks are essential requirements of the system.

Cross bar says that its filamentary-based ReRAM has been demonstrated to provide unique levels of security, including strong resistance to attempts to read the memory through invasive physical hacking. Cross further says that MicroNet Solutions (MSI) performed extensive delayering and inspection of CrossBar's ReRAM memory silicon through imaging techniques in an attempt to determine its stored content. After significant evaluation using sophisticated techniques such as measuring electron beam induced current and passive voltage contrast imaging, MSI was unsuccessful in determining the contents of the memory array.

Fujitsu Semiconductor Memory Solution announced the launch of a 12Mbit ReRAM chip, the MB85AS12MT. Fujitsu says that evaluation samples are currently available.

The MB85AS12MT offers a small package size (2mmx3mm) and a low level of average read current (0.15mA). Fujitsu targets applications in wearable devices such as hearing aids and smart watches.

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.

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.’
