Under the agreement, DB HiTek has licensed Weebit ReRAM for its customers to integrate as embedded non-volatile memory. Weebit ReRAM technology will be available in DB HiTek’s 130nm Bipolar-CMOS-DMOS (BCD) process, which is used in analog, mixed-signal, and power designs in consumer, industrial and other IoT devices. DB HiTek also has the option to use Weebit ReRAM for other process nodes.

4DS Memory achieved better-than-expected results from latest memory system testing

Australia-based RRAM developer 4DS Memory  announced that it has achieved “significantly better than expected” analysis results from testing of its latest memory system offering known as the Fourth Platform Lot wafer. 4DS says that the notable improvements to the 4Ds Platform Lot technology has been supported by the company’s ongoing collaboration with world-leading R&D and innovation hub in nanoelectronics and digital technologies developer, imec.

Mr Yen said the company has also proven that 4DS Interface Switching ReRAM technology is transferable, while demonstrating a fully functional megabit array with 4DS Interface Switching ReRAM memory cells. Notably, the tests also highlighted consistent read and write speeds equivalent to DRAM and proven endurance in excess of 2 billion cycles at DRAM read and write speed on a megabit array.

The fund raising took part through the placements of 12 million new shares to international institutional investors, as well as an oversubscribed share purchase plan (SPP) to existing shareholders.

In early 2023 Weebit taped-out demonstration chips integrating its embedded RRAM module in an advanced 22nm FD-SOI process technology. In November 2022 the company announced that it has received the first silicon wafers from SkyWater Technology, with embedded Weebit RRAM.

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.

Weebit Nano taped-out its first 22 nm demo RRAM chip

Israel-based RRAM developer Weebit Nano announced that it has taped-out (released to manufacturing) demonstration chips integrating its embedded RRAM module in an advanced 22nm FD-SOI (fully depleted silicon on insulator) process technology.

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.

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.
