Intrinsic Semiconductor Technology raises $8.4 million to bring its RRAM technology to market

UK-based Intrinsic Semiconductor Technologies (Intrinsic) has raised $8.4 million USD to further develop and commercialize its RRAM memory technology. The funding was led by Octopus Ventures, and was supported by existing investors and the UK government.

Intrinsic was spun-off from University College London (UCL) in 2017. The company's main technology is a silicon-oxide based RRAM memory, which is said to be fully air stable and inherently CMOS compatible. The company says its memory devices will be cheaper and easier to produce compared to competitive technologies.

GlobalFoundries acquires CBRAM technology from Renesas Electronics

GlobalFoundries announced that it acquired RRAM technology from Renesas Electronics, for use in chips for home and industrial IoT devices and smart mobile devices.

The RRAM technology originated at Dialog Semiconductor, which Renesas acquired. In 2020, Dialog licensed its CBRAM technology to GlobalFoundries. Dialog's RRAM technology, in turn, was developed by Adesto Technologies which was acquired by Dialog in 2020.

Infineon to adopt TSMC's embedded RRAM in its next-gen Aurix microcontrollers

Infineon says that its next generation Aurix TC4x microcontrollers will adopt RRAM memory, instead of the traditional embedded flash. The company expects the first samples of such chips to ship to customers before the end of 2023.

Infineo's next-gen Aurix chips will be produced at Taiwan Semiconductor Manufacturing Co (TSMC), using its 28nm CMOS process. The company says that RRAM memory will be more energy efficient at 28nm compared to the currently-used embedded flash memories. The RRAM memory will also enable higher disturb immunity and it allows for bit-wise writing without need for erase, which allows for superior performance over embedded flash. The cycling endurance and data retention are comparable with flash.

Weebit Nano receives the first RRAM-enabled silicon wafers from SkyWater Technology

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.

Weebit Nano shows a demo of its RRAM neuromorphic memory at Flash Memory Summit

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.

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

Crossbar targets new application for its RRAM memory, where resistance to physical attacks is essential

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.
