More fancy new memory, STT-RAM from Avalanche

STT-MRAM, Spin Transfer Torque Magnetic Random Access Memory, actually uses the spin of an electron to record a 1 or 0 making it quite scalable, though Avalanche's current proof of concept is built on a 55nm process.  Avalanche is hoping that their use of the common Serial Peripheral Interface bus and standard CMOS 300mm process will make this type of RAM easier to adopt than some of the other types of non-volatile RAM being developed such as RRAM, NRAM and Toshiba's STT-MRAM.  STT-MRAM can be incredibly fast, scale down well below 10nm and will not need multiple layers, which will reduce the heat produced even in extremely high densities.  Check out more on how they have designed their version of STT-MRAM over at The Register.


"Startup Avalanche is sampling an STT-RAM chip offering DRAM/SRAM speed, persistent storage, unlimited endurance and scalability beyond 10nm."

NRAM research gets a financial boost

Non-volatile memory technology is now at a turning point where we find out which technology will be doomed to be BETAMAX and which will carry on to become the VHS equivalent; hopefully that analogy is not too accurate as VHS was not the better of the two.  Allyn discussed the reasons why the market is looking for a new technology back in 2012 and his predictions that NAND still had some life in it have been proven over the past few years but we are seeing new limitations with the current technology.

In the past we have covered HP's Resistive RAM, also called a Memrisitor, which has been in development for many years but has finally appeared in some Panasonic microcomputers which control sensors.  STT-MRAM, spin transfer torque magnetoresistive random access memory, is Toshiba's project and while we still haven't seen any product it has been in development for more than 3 years and news of prototypes should arrive soon.  Lastly is NRAM, nano-RAM so named for the use of carbon based nanotubes in its design which is being developed by Nantero.

It is Nantero which is in the news today, having secured $31.5 million in funding this year, triple what they have seen in previous years according to the numbers The Inquirer has.  This particular technology offers densities in the terabytes per chip, storage which requires no active power source once written to and data retention of over 1,000 years at 85 degrees Celsius.  The speeds should match those expected from STT-RAM but at a fabrication price closer to the much lower cost RRAM; don't hold off buying your next SSD but do not think that market is going to get boring any time soon.


"It got $31.5m in an over-subscribed round to continue developing its nanotube-based non-volatile RAM (NRAM) semiconductor technology, which it says has DRAM read/write speed and is ultra-high density – think terabits."

Panasonic Launches New Microcomputers With ReRAM Storage

Subject: General Tech | August 6, 2013 - 04:27 PM |
Tagged: RRAM, Panasonic, memristor

RRAM (Resistive RAM) and "Memrisitor" non-volatile memory technology has been theorized about in the past, but it is finally starting to make its way into actual products. Specifically, Panasonic announced a new series of 8-bit MN101R microcomputers that feature RRAM memory for storage.

The Panasonic microcomputers are intended to be used in environmental sensors, healthcare monitors (blood pressure, activity, et al), fire alarms, and electronic passports. Panasonic expects to ship a million of these ReRAM-equipped boards a month. The company claims that the move from NAND flash to ReRAM results in up to a 50% power savings and increased memory durability supporting as much as 10-times higher re-write cycles. Additionally, the ReRAM is five times faster at writes than both NAND flash and EEPROM due in part to not having to perform a data erase during each write.

Panasonic and Crossbar (a start-up working on RRAM) have some impressive figures to share, but enthusiasts should not get their hopes up just yet. The Panasonic microcomputers are using a scant 64KB of ReRAM paired with 4KB of SRAM. While a good first step, the technology still has a ways to go before we start to see it enter mobile devices and traditional PCs.

With that said, it does have a lot of potential, and I’m excited to finally see an actual physical product come out of all the resistive RAM research!

Resistive RAM comes closer to reality

Resistive RAM has been one of the technologies that we have heard of which could become the next standard in non-volatile RAM.  The technology promises high density storage, RAM level read and write speeds and a long storage life but while there has been a lot of research into this type of memory we haven't seen any commercially viable products being announced.  A company called Crossbar could change that with their new implementation which claims that it is ready to go into production with an impressive display of technological advancement.  They tout 20 times the write speed of NAND with 20 times less the power consumption as it is non-volatile and does not require electricity to hold data.  With an estimated 20 year life for any data stored on the media this could be a great long term storage solution; not just high availability data that needs the high write speeds.  Thanks to the use of 3D storage they can fit 1TB of data on a single 200mm2 chip.  Read more at The Inquirer.


Not this kind of Crossbar

"CALIFORNIA CHIP STARTUP Crossbar has unveiled what it claims is the first commercially viable Resistive RAM (RRAM) memory chip, a new generation of non-volatile memory capable of storing up to 1TB of data on a single 200mm2 chip."
