RRAM-Info: the RRAM experts

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

Crossbar and Mobiveil to support Crossbar's RRAM IP on Mobiveil's solid-state storage IP

Sep 14, 2017

Crossbar logoCrossbar announced a partnership with Mobiveil, a supplier of silicon IP, platforms and IP-enabled design services to apply Mobiveil complete PCIe to NVMe set of solid state drive (SSD) IP to support Crossbar's RRAM IP blocks.

Mobiveil and Cross will work together on a new RRAM-based design from Mobiveil’s complete PCIe-to-NVMe set of SSD IP with Crossbar’s RRAM enabling six-million 512B IOPS below 10us latency. Crossbar says that the performance gain will enable RRAM-based SSDs to significantly speed up access to frequently requested information in large data centers.

Crossbar ramps up 40nm RRAM production, signs-up 12 MCU/SoC companies as licensees

Sep 01, 2017

Crossbar logoIn March 2016 Crossbar announced its strategic partnership with Semiconductor Manufacturing International Corporation (SMIC) to co-develop and produce RRAM technologies. In January 2017 Crossbar announced that it started sampling RRAM chips.

In an interesting interview with Electronic Design, Crossbar's Vice President of Strategic Marketing & Business Development, Sylvain Dubois, discloses that Crossbar has started to ramp up production, and has signed a dozen agreements to license its technology to MCU/SoC companies. Crossbar's current developments are targeting embedded ReRAM IPs integrated in MCUs/SoCs for IoT, consumer electronics, artificial intelligence, and industrial applications.

Researchers show that short weak pulses can be used to switch RRAM states

Aug 11, 2017

Researchers from the NIST in the US have found that short, weak energy pulses can be used to change RRAM states. This method is much more efficient and reliably than current switching techniques.

RRAM switching states (NIST)

The researchers explain that current RRAM devices use single relatively high-energy pulses in order to switch the state (on / off, or 1 / 0). This is an unreliable method. The researchers have now discovered that short pulses (only 100 picoseconds in total), even very weak ones, are useful to switch the state.

Researchers combine RRAM and logic in a single 3D CNT chip

Jul 06, 2017

Researhcers at Stanford and MIT developed a new 3D chip fabrication method that combines a CNT-based processor with RRAM memory cells. This technology can be used to create 3D chip architectures in a way that is not possible with silicon-based chips.

Both CNT-based logic and RRAM memory components can be deposited at relatively low temperatures (around 200 degrees Celsius) as opposed to silicon which requires 1,000 degrees to deposit. This means that you can place one layer on top of the other without damaging either layers.

Researchers use ALD coating tech to successfully deposit RRAM functional layers

Jun 28, 2017

Researchers at Moscow's Institute of Physics and Technology (MIPT) developed a method of depositing the functional layers of an RRAM memory cell using high quality ALD coating. The researchers report that ALD enables a controllable growth of oxygen deficient oxides.

The MIPT researchers used production-proven ALD equipment made by Picosun. The researchers now want to see whether the ALD process can be scaled to an industrial-scale production process.
