Mark Stiles, from the NIST's Center for Nanoscale science and technology, gave an interesting lecture titled "Spin Current: the Torque Wrench of Spintronics" in which he discussed spintronics challenges, especially for spin-torque memory devices:
Here's an interesting video interview with Joe O'Hare, Everspin's Director of Product Marketing. Joe explains the company's MRAM (and ST-MRAM) tech and business, especially how it relates to enterprise SSD, which seems to be the focus of MRAM applications at the moment:
During the interview, Joe updates that everspin is now designing a 256Mb chip, and this will be the next product the company will introduce. Currently their highest-density chip is the 64Mb ST-MRAM chip (announced in 2012, but only ramped-up recently).
Tweaktown posted an interview with Everspin's CEO, Philip LoPresti, who explains the company technology and business.
Philip says that while Everspin currently ships only 64 Mbit STT-MRAM, they have plans to increase the density up to a Gigabit within the next few years.
Micron announced that it is now mas-producing 45-nanometer Phase Change Memory (PCM) for mobile devices, featuring 1-gigabit (Gb) PCM plus 512-megabit (Mb) LPDDR2 in a multichip package. This is the first time that PCM memory is available in volume production.
The 45nm PCM is targeted for feature phones, with a future roadmap aimed at addressing smartphones and media tablets.
Veeco produced a nice ad showing their NEXUS Ion Beam Deposition System. This tool is "ideal for MRAM applications" and can also be used for read/write heads used in hard disk drives:
Researchers from the National Institute of Standards and Technology (NIST) and University of Colorado Boulder (CU) developed a new chip that uses microfluidics and magnetic switches to trap and transport magnetic beads. This low-power device may be useful for medical devices. This technology may also lead us towards "MRAM" chips used for molecular and cellular manipulation.
In the past, magnetic particle transport chips required continuous power and even cooling. This new technology manages to overcome the power and heat issues, and offers random-access two-dimensional control and non-volatile memory. The prototype chip uses 12 spin valves (commonly used as magnetic sensors in HD read heads) which are optimized for magnetic trapping. Pulses of electric current are used to switch individual spin valve magnets “on” to trap a bead, or “off” to release it, and thereby move the bead down a ladder formed by the two lines. The beads start out suspended in salt water above the valves before being trapped in the array.
