MRAM-Info upgraded

MRAM-Info was upgraded today (if anyone is interested, we upgraded to Drupal 6.x from 5.8). Most of the changes are infrastructure related so you won't notice much, but hopefully the site should be faster now, more stable and more secure.
If you do find any bugs, glitches or you have any comments, please let us know!

New Graphene-Info site launched

We're happy to announce a new addition to the Metalgrass site network: Graphene-Info. Graphene is a sheet, one-atom-thick of carbon atom, in a honeycomb crystal lattice. If you use many layers of graphene, stacked one on top of the other, you’ll get Graphite. Graphene has many uses - Spintronics, sensors, ICs (for example a transparent backplane for OLEDs), ultra-capacitors and more.

Graphene-Info

We hope you'll enjoy the new site...

MRAM-Info site redesign

We have updated our site's design... with a much cleaner look. Hopefully this will make reading and finding information easier.

I'd love to hear your comments on the new look!

Crocus' CEO: we'll have an MRAM product by end of 2009 - smaller, cheaper and better than Everspin's MRAM

Jean-Pierre Braun, the CEO of Crocus technologies, is visiting Israel these days, and I had the good chance of meeting him. Crocus' technology is based on work done by the French Spintec research center. In fact they get an exclusive access to Spintec MRAM related research and patents for the next 15 years.

Crocus' technology

Crocus' basic technology is based on Field-Induced MRAM (Toggle MRAM), which is in some ways similar to Everspin's technology (or 1st generation MRAM). Historically, Field-Induced MRAM is very hard to scale, and has stability and retention problems. Crocus aims to solve all this using a thermally activated magnetic latch. They call their technology Thermally Assisted Switching or TAS. Basically this means that the latch helps the cell retain the memory value very well. It can also scale quite well. This also (theoretically) will allow them to pack more than 1 bit per cell... some day.

Jean-Pierre says that many companies are doing 'Thermal MRAM' - which only means heating the material for easier handling. But Crocus technology is very different - because of the use of this magnetic latch, not just heat by itself.

Crocus plans

Crocus already has a 'small' (few KBits) working sample of their memory, and towards the end of 2009 they will hopefully get a real product out. I can't say much yet, but this product will have a higher-density than Everspin's products (currently 4Mbit), smaller size and will also be considerably cheaper. This is great news, and hopefully they'll be able to pull it off. Even though the largest MRAM market is for embedded memory, the first Crocus product will be stand-alone.

Crocus financials

Obviously these are hard times - especially for start ups and companies that are still losing money. Crocus has already raised around US$30M, but they aim to break-even in 2010 or 2011. They will still require another round of investment, but hopefully a small one.

Future plans

Crocus are also working on STT-RAM. Jean-Pierre thinks that the best way forward is Perpendicular STT-RAM, which is currently lead by Toshiba. Crocus' MRAM road map looks like this -

Interview with Vincent Chun from Spin Transfer Technologies

In October 2008, I had the chance of interviewing Vincent Chun from Spin Transfer Technologies. Vincent Chun is the executive in charge at Spin Transfer Technologies. He is also a Director of Allied Minds, the investment firm that provided pre-seed funding for STT. Dr. Chun has 23 years of experience in science, technology, and corporate and entrepreneurial business management. He has a Ph.D. from MIT and an MBA from Kellogg. Spin Transfer Technologies was jointly formed by Allied Minds and New York University, using technology developed by Dr. Andrew Kent at NYU’s Physics Department.

* Can you explain your STT-MRAM technology?
Spin Transfer Technologies’ MRAM innovation utilizes a deterministic mechanism to rotate the magnetization vector of a free magnetic layer. This is made possible by using an orthogonal orientation between the magnetization of the pinned and free magnetic layers. Because the magnetization reversal mechanism does not rely on thermodynamic processes to initiate the switching, there is no incubation delay – and the switch time is very short, while the power consumption is very small compared to spin-transfer techniques used by others. We call our technology Orthogonal Spin Transfer MRAM or OST-MRAM for short.


* How many people work in STT currently?
Eight people are involved in STT activities at the moment.


* What is your plan? Do you want to license your IP, or perhaps try to make the chips yourself or with a partner?
We plan to make the chips with one or more partners, but will certainly be open to licensing the technology as well.

MRAM Related Invention Looking For Funding Or Buyout

We've been approached by "VCPartners" who have an MRAM related invention and are looking to sell it or get funding. The invention is titled "HIGH SPEED MAGNETIC RANDOM ACCESS ELECTRONICALLY CONTROLLED MEMORY" and here's their abstract:

There is presented the principally new magnetic core memory device (hereinafter MD) with use of new principle of memory control, which allows to create fully featured high-speed operative memory with random access on magnetic elements with several unique characteristics.
Feasibility and efficiency of the technology is proved experimentally. We have the working model of MD according to the invention. The invention exists in form of “know-now” and has no patent protection. We want to commercialize the invention together with interested companies or to sell it.
