"Sneak Path" Breakthrough Heralds Arrival Of Ultra-High Density Resistive Memory

Contributed Article by CrossBar’s Sung Hyun Jo, Ph.D.

As floating-gate flash memory technologies used in the majority of products on the market today quickly approach the limits of their ability to scale to higher densities, it has become widely recognized that a new non-volatile memory technology is needed to replace them. Resistive random-access memory (ReRAM) is widely hailed as the “most likely to succeed” in the race to replace today’s flash memory with a new, more scalable, higher-capacity, higher-performance and more reliable non-volatile memory. While many companies are actively pursuing ReRAM technologies, however, the road to creating commercially viable ReRAM products has not been easy.

CrossBar gets around a nasty obstacle to dense 3D memory chips
Creating 3D memory chips isn’t too hard. But packing the memory cells so they contain a lot of dense storage is a problem that has bedeviled chip makers for a while. But memory chip startup CrossBar says it has figured out a way to create 3D structures with a lot of densely packed circuitry. The result could be memory chips that can store a ton of data in a very small space. Santa Clara, Calif.-based CrossBar disclosed what it called a breakthrough innovation at the 2014 International Electron Devices Meeting in San Francisco today. It will enable high-density storage with faster response times and lower power consumption. As such, it could be useful in everything from data centers to smartphones.

CrossBar breaks 3D storage barrier
3D is the memory chip buzzword du jour, because reducing feature sizes is expensive, while stacking memory cells up is much less so. Fabs can use older, stable processes to build larger capacity chips with less technical risk. Samsung has announced products using their 3D flash. But NAND flash is not the only memory technology that can benefit from 3D economics. Where speed and reliability are critical various forms of Resistance RAM (ReRAM or ReRAM) are starting to make inroads. CrossBar, a venture-backed startup in Silicon Valley, is pushing the 3D bandwagon even further.

CrossBar ReRAM Tweaks Nonvolatile Memory

By Jim Turley

I gotta say, memory chips are boring.

And that’s coming from a guy who lives and works in the chip business. Sure, I can get all excited about microprocessor chips. I can generally keep my eyes open through a discussion of interface chips. I’ve even been known to nod occasionally when the topic turns to cryptography chips. But memory? Give me some toothpicks for my eyelids.

CrossBar's Resistive RAM claims milestone, but future ship date remains unclear

By Carol Sliwa

Many enterprises are still getting a handle on the best ways to use NAND flash, but they can already scope out some of the potential successors to the solid-state storage technology.

CrossBar Inc. specializes in non-volatile 3D Resistive RAM (ReRAM), which promises greater endurance and higher density than NAND flash. The Santa Clara, California-based startup claims that it reached an important milestone toward commercializing terabyte-scale memory arrays that can use a chip the size of a postage stamp.

CrossBar Has 1Mb ReRAM

By David Manners

CrossBar, the four year-old Santa Clara resistive RAM (ReRAM) start-up, has demonstrated pre-production 1Mb arrays. The array uses CrossBar’s using its patented “1TnR” (1 Transistor driving n Resistive memory cells) technology which makes it possible for a single transistor to manage a very large number of interconnected memory cells, enabling very high capacity solid-state storage.

Other memories utilising passive cross-point architectures, such as Resistive RAM, PCM (Phase Change Memory) and neuromorphic systems, experience unintended electrical current when accessing high density storage due to “sneak path current.” .

New chips promise faster computing

New computer chips that have instant-on capabilities found in tablet devices but also provide higher performance, will change the way people use personal computers, according to an industry analyst.

Continuing research in solid-state technologies are leading to the development of so-called magnetoresistive random access memory (MRAM) and resistive random access memory (ReRAM) chips that offer many advantages over conventional DRAM (dynamic random access memory) chips, according to Tom Coughlin, founder of Coughlin Associates, a data storage consulting firm.

DRAM chips store data using an electrical charge in each memory cell. Capacitors used in DRAM chips lose their charge over time and memory assemblies using DRAM must refresh all the cells in their chips approximately 20 times per second. As DRAM cell decrease in size their need to refresh increases.

New types of RAM could revolutionize your PC

New chips that blur the line between computer memory and storage are starting to move beyond niche applications and could change how we use PCs, an industry analyst said Sunday.

The chips would enable the same instant-on capability that’s common on tablets, but at much higher performance, said Tom Coughlin, founder of Coughlin Associates.

“We’re seeing the development of new solid-state storage technologies that are starting to play a role,” he said. “MRAM is one that we’re seeing playing a role providing a non-volatile memory technology, and there’s some talk about resistive RAM doing some things.”.

What's After 3D NAND?

By Mark LaPedus

Planar NAND flash memory is on its last scaling legs, with 3D NAND set to become the successor to the ubiquitous 2D technology. Samsung Electronics, for one, already has begun shipping the industry’s first 3D NAND device, a 24-level, 128-gigabit chip. In addition, Micron and SK Hynix shortly will ship their respective 3D NAND devices. But the Toshiba-SanDisk duo are the lone holdouts, as the joint venture partners will extend planar NAND as long as possible before rolling out a 3D NAND device in 2016.

Storage Tech to Look Out For
Last month we saw some major developments in two storage technologies - Vertical NAND (V-NAND) and Resistive RAM (ReRAM) - which have the potential to change the way we view storage. We currently have two choices - spinning mechanical hard drives and flash based solid state drives (SSD). The spinning hard drives still offer the best cost per GB as compared to flash-based SSDs, but each of these technologies come with their own set of issues. Hard drives lack the speedy access times and low-power goodness offered by an SSD. The only way to currently get the best of both worlds - lower cost per GB and fast access times - is to invest in a hybrid .drive. But as far as SSDs are concerned, while the costs may have come down, they are still grappling with their own set of issues.
