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 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.
Israel-based SiOx RRAM developer Weebit Nano announced that it has signed a letter-of-intent with China-based SiEn QingDao Integrated Circuits to jointly investigate ways in which Weebit’s
technology can be used in SiEn’s products.
SiEn is a Communal Integrated Device Manufacturer (CIDM) company, which aggregates companies with similar target markets, technologies, production lines and customers to share common manufacturing technology production goals. Weebit hopes that its RRAM technology will
enhance SiEn’s competitive position by adding significant non-volatile memory capability to its future products.
Israel-based RRAM developer Weebit Nano Announced that it is launching a new program to address the needs of the discrete memory market
Weebit says it is accelerating its entry into the discrete, stand-alone, memory chip market. Weebit says that a key element required for discrete memory chips is the selector, which helps isolate the memory cells so that only the specific cells which should be modified actually are, and all the other cells are disconnected and not impacted.
In August 2019 Israel-based SiOx RRAM developer Weebit Nano announced that it has signed a letter of intent with XTX Technology to investigating ways in which XTX can use Weebit’s technology in its products. Today Weebit announced that XTX verified the technical parameters of Weebit's ReRAM technology and reproduced the results previously achieved with Leti.
Weebit says that this successful external testing with XTX was achieved four months ahead of schedule. The two companies are now investigating ways to integrate Weebit's ReRAM memroy technology into XTX Products.
Sony announced that it is accelerating its RRAM ("Cross Point ReRAM") development with an aim to commercialize it in 2020. Sony says that its ReRAM will be cheaper than NAND, and also faster, consumer less power and heat. Sony's efforts at this stage are to develop a smart low-power ReRAM controller, reduce the power consumption and manage the thermal issues.
As can be seen in the slide above (click to enlarge), Sony says its 128GB ReRAM drives will feature 25.6 GB/s read times, 9.6 GB/s write times and will support PCIe gen5 x 5. The power consumption target is 14.6W. The larger 16-chip 256GB drives will be faster at 51.2 GB/s read and 19.2 GB/s write. The power consumption will be 27.2W.
