MRAM News, Resources & Information
MRAM is a next-generation memory technology, based on electron spin rather then its charge. Often referred to as the "holy-grail of memory", MRAM is fast, high-density and non-volatile and can replace all kinds of memories used today in a single chip.
In November 2013, Crocus Technology filed an Inter Partes Review petition to the US PTO, claiming that Spin Transfer Technologies's US patent #6,980,469 describes a technology already used in prior art, in particular in the patent portfolio of Crocus.
Crocus Technology now says that the USPTO issued a preliminary decision in favor of Crocus' petition - saying that there is a “reasonable likelihood” that Crocus will prevail with respect to its challenge. The patent in question describes a high-speed low power magnetic devices based on current induced spin-moment transfer.
In January 2013, NVE filed a patent infringement lawsuit against Everspin Technologies. A few months later, Everspin filed a patent lawsuit of their own against NVE.
Yesterday NVE announced that the two companies agreed to drop both lawsuits and will not assert the patents in those suits against each other in the future. NVE says that this agreement (which seems to be a appointment's to their shareholders) is limited to the patents in the 2012 lawsuits.
Back in June 2013 Samsung Electronics launched a global research outreach program aimed towards STT-MRAM innovation. The Samsung Global MRAM Innovation (SGMI) wanted wanted to reach out to colleges, universities and research labs from all over the world to explore breakthrough and innovative STT-MRAM research.
Samsung ran a short ad campaign on MRAM-Info and Spintronics-Info to help discover partners. Samsung informed us that they received lots of best and most novel proposals on a range of compelling research subjects. They are now collaborating with 15 SGMI partners. Hopefully we'll someday hear of the advances made through these collaborations.
Avalanche Technology has been awarded four key "milestone" patents for its STT-MRAM technology and solid-state storage array system design. Avalanche has over 200 filed patents that covers the full spectrum from memory cell/circuit design and manufacturing to solid-state storage system development and deployment.
Avalanche (founded in 2006 and based in California, US) developed patented Spin Programmable STT-MRAM (SPMEM) memory that uses a revolutionary proprietary spin current and voltage switching technology. The company wants to license their technology for embedded applications and also build discrete standalone memory devices. In July 2012 the company raised $30 million.
I'm happy to announce that MRAM-Info's infrastructure was updated today. MRAM-Info is based on the open-source Drupal CMS, and we updated from version 6 to version 7. As a reader you will not find many differences, but hopefully it will enable a more stable, safe and quick web site.
If you do find any bugs or glitches, please let us know.
Crocus Technology announced that ARM licensed the company's Magnetic Logic Unit (MLU) technology. The MLU is a CMOS based rugged magnetic technology capable of offering important advantages in performance, size and security for embedded micro-controllers. MLU can replace both flash and RAM and are suitable for mobile and security applications.
Crocus will provide ARM with access to its MLU technology, including MRAM blocks in sub-90 nm technology which can replace traditional flash memory, plus MIP (Match In Place) enabled technology which enhances the security of keys and other secret data. Crocus has been co-developing the MLU technology together with IBM since 2011.
