RRAM-Info: the RRAM experts

Dialog Semiconductor announced that it has has entered into an agreement with GlobalFoundries in which Dialog licenses its Conductive Bridging RAM (CBRAM) technology to GF. Dialog's RRAM technology was pioneered by Adesto Technologies which was recently acquired by Dialog Semiconductor in 2020.

GF will first offer Dialog’s CBRAM as an embedded, non-volatile memory (NVM) option on its 22FDX platform, with the plan to extend to other platforms. Dialog’s proprietary and production proven CBRAM technology is a low power NVM solution designed to enable a range of applications from IoT and 5G connectivity to artificial intelligence (AI).

TSMC is developing RRAM technologies for several years, and the company first hoped to introduce its first embedded RRAM in 2019. This did not happen, but the company says it is now on track for first customer tape-outs in the second half of 2020.

TSMC will offer RRAM on its 40nm and 22nm manufacturing processes.

Australia-based RRAM developer 4DS Memory announced that it has raised a total of $7.6 million AUD ($5.45 million USD) in two financing round.

4DS Memory says that it will use the funds to further develop its Interface Switching ReRAM technology with imec and Western Digital's subsidiary, HGST.

Researchers from Korea's Pohang University of Science & Technology (POSTECH) has designed a halide perovskite material for RRAM memory devices. The perovskite material offers low-operating voltage and high-performance resistive switching memory.

The researcher say they have succeeded in designing an optimal halide perovskite material (CsPb2Br5) that can be applied to a ReRAM device by applying first-principles calculation based on quantum mechanics.

Israel-based RRAM developer Weebit Nano announced it has raised $6.6 million AUD via a two-tranche placement. The funds will be used to complete its memory module development, transfer the technology to a production fab and continue its work on discrete RRAM memory technology.

Weebit says that the placement was priced at a discount of around 22% to its current share price. The company now hopes to accelerate its development work and make up lost time from the COVID-19 shutdown.

GigaDevice, a provider of non-volatile memories, MCUs and sensors announced an RRAM patent licensing agreement with Rambus and Reliance Memory (which is a Joint Venture between GigaDevice and Rambus established in 2018).

Under these agreements, GigaDevice obtained licenses for more than 180 RRAM technology-related patents and applications from Rambus and Reliance Memory.

Singapore's A*STAR Institute of Microelectronics (IME) announced that it has strengthened its collaboration with Picosun Group in the area of next-generation memories.

Picosun provided ALD solutions and consultancy to IME to assist in the development work on FeRAM and ReRAM technologies.Picosun's ALD equipment supports 12" wafer processing.
