The Newest Spin on Electronics

06/12/2007 8:24 AM

In 1948, scientists at Bell Labs created something called a transistor, igniting the spark that has created the entire semiconductor industry and all of its progeny. Now, engineers at the University of Delaware hope to place the industry atop another precipice. They have created a technique for controlling a computer's ones and zeros using the spin in silicon electrons (spintronics) when they experience a magnetic field instead of an electric charge. The resulting circuitry will be many times faster than existing solutions and will extend the life of silicon as the primary (and least expensive) semiconductor substrate material. View a video on spintronics.

I'm using spintronics (I really hate that name) now. NVE makes a line of magnetic sensors and isolator chips that we are evaluating for space flight (the magnetic nature of spintronics is especially radiation tolerant) and we plan on using Honeywell's nonvolatile magnetic memory, NVMRAM, which is already qualified as radiation hardened, based on the same technology.

You can see real world devices at www.nve.com (no, I don't work there, or own stock - yet).

Are the Honeywell NVMRAMs USML?

If you mean are they US MIL - they don't have a DSCC drawing as of yet, but they are qualified through MIL-STD_883, TM 5005 Class S, and screened to QML level V.

The data sheet is here:


p/n is HXNV0100

Close. Actually, USML refers to the U.S. Munitions List and articles and information/technology listed on the USML require an export license for the article/information/technology to be exported from the U.S. or transferred to a non U.S. person. If these RAMs were designed FOR the military, they are likely USML. If they were not designed FOR the USML but do meet a mil spec., they may be USML.

We would call that ITAR, I guess.

I suppose it would fall into the category of space electronics which is

(1) scheduled to be moved to the licensing jurisdiction of the Department of Commerce upon establishment of a foreign policy control or (2) in the case of spacecraft and related equipment, the item is under review by an interagency space technical working group. The interagency review will result in a recommendation as to whether an item should be moved to the jurisdiction of the Department of Commerce or to USML category XV which was established for this purpose.


So, probably you'll want to get these to North Korea via a dummy corporation - maybe smuggle them out in bags of wheat.

For the record:

I, Texlex@CR4, would never, under any circumstances, endeavor to compromise U.S. interests or world security, as interpreted by any U.S. agency charged with administering U.S. export control laws or developing U.S. export control policy, by advising, assisting, or conspiring to violate any clearly stated U.S. export laws, regulations, or policies, and certainly not using wheat, gluten, chaff, stem, stalk, roots, germ, or any other portion of the wheat kernel or its associated organic plant matter, to North Korea. <<<signed with a pound of former flesh>>>

Yes, the ITAR was promulgated to administer U.S. export controls of USML articles. Many people refer to ITAR, but I prefer to idenfy the jurisdiction of the articles based on whether they are USML or not. The answer determines whether the ITARs attach or whether export control is governed by another agency and another set of regulations. I can tell from your response though that, no matter the slight difference between our styles of referring to the subject matter (2 sides of the same coin), you have had some significant exposure to the topic. I feel your pain.

Yes - 20 years on the U2.

Now, I'm in space - where no one can hear me scream.

I have several clients that provide marine and/or airborne survey and positioning services using USML Cat. VIII(b) and/or XII(d) articles and other equipment that is CCL. I would imagine some of the inertial/gyro hardware is very similar to what the U2 uses or has used to meet its navigation and positioning needs
