Speciality electronics outfit boasts of 64-fold density increase for its latest space-ready MRAM parts

Takes Avalanche's latest STT-MRAM tech and packs it into rad-hard ceramic squares


Electronics outfit Micross has announced the launch of a 1 gigabit magnetoresistive RAM (MRAM) component, its highest-density part yet - and a device it hopes will prove the future of spintronics for high-reliability computing in harsh environments.

Packaged in 18x20mm ceramic land-grid array (LGA) and ball-grid array (BGA) formats, the compact Micross chip represents the company's highest-density MRAM part yet - all part of its attempts to convince a range of markets that the spintronics-based MRAM, which stores data as magnetic elements rather than electric charges or current flows, is the superior choice for high-reliability electronics.

The new part isn’t designed to replace dynamic or static RAM, for all that Micross provides it with an SRAM-compatible interface. Instead, the company positions MRAM products as an alternative to flash storage - but with an inherent resistance to “harsh environments,” explaining the company’s target markets of aerospace, defence, space, and industrial.

Avalanche, the company behind the MRAM inside Micross' chip, announced its launch of spin-transfer torque magnetoresistive RAM (STT-MRAM) technology back in 2015, at the time using a 55nm process but targeting a transition to a sub-10nm process as manufacturing capabilities matured.

The version of Avalanche's STT-MRAM tech powering the Micross part has dropped to a 22nm process node, which undoubtedly helped the companies deliver the impressive density gains seen in the new release: a sixty-four-fold boost over Micross' original MRAM part, which held just 16Mb.

"Avalanche's next-gen 22nm Perpendicular Spin Transfer Torque MRAM technology has enabled Micross to provide greater SWaP [Size, Weight, and Power] savings through the addition of our 1Gb Hermetic MRAM to Micross' hi-reliability memory portfolio," claimed Jeremy Adams, vice president of products and services at Micross, in a prepared statement.

"Micross' 1Gb MRAM offers more than 64x the density of our initial 16Mb MRAM, with an improved bit density per mm² of 2.844Mb as compared with a bit density per mm² of 163.84kb. The low power, infinite endurance, high performance and scalability of Avalanche's next generation STT-MRAM technology allows Micross to continue delivering the world's most compact and efficient, non-volatile hi-reliability memory solutions for the aerospace and space industries."

The part, which is available in standard, radiation-tolerant, and radiation-hardened variants for those who need such things, offers over 10 years of data retention across a -40°C to +125°C temperature range - and a stable 45ns access time across its operating temperature range, too, the compan claimed.

Micross isn't alone in offering MRAM parts, however: in 2019 Samsung began shipping embedded MRAM (eMRAM) built on a 28nm silicon-on-insulator process node, a year after Everspin offered MRAM tech as an add-in card for servers and workstations. The heart of the technology, meanwhile, dates back to work at IBM in 1974 which would eventually see use in a prototyped MRAM chip in 1998.

The Reg asked Micross for pricing information on the new parts byt the company didn't respond in time for publication. Interested parties are free to contact the company through its website. ®

NFTs not annoying enough? Now they come with wallet-emptying malware

Plus rifle-toting robot dogs, but makers insist they're really dumb

In brief Whether or not non-fungible tokens are a flash in the pan or forever, malware operators have been keen to weaponise the technology.

An investigation was triggered after a number of cryptowallets belonging to customers of the largest NFT exchange OpenSea got mysteriously emptied. Researchers at security shop Check Point found a nasty form of NFT was in circulation, one that came with its own malware package.

People were receiving free NFTs from an unknown benefactor, but when they accepted the gift the attackers got access to their wallet information in OpenSea's storage systems. The code generated a pop-up, that if clicked, allowed wallets to be emptied.

Bank manager tricked into handing $35m to scammers using fake 'deep voice' tech

Plus: Microsoft Translator machine learning software now supports over 100 languages

In brief Authorities in the United Arab Emirates have requested the US Department of Justice's help in probing a case involving a bank manager who was swindled into transferring $35m to criminals by someone using a fake AI-generated voice.

The employee received a call to move the company-owned funds by someone purporting to be a director from the business. He also previously saw emails that showed the company was planning to use the money for an acquisition, and had hired a lawyer to coordinate the process. When the sham director instructed him to transfer the money, he did so thinking it was a legitimate request.

But it was all a scam, according to US court documents reported by Forbes. The criminals used "deep voice technology to simulate the voice of the director," it said. Now officials from the UAE have asked the DoJ to hand over details of two US bank accounts, where over $400,000 from the stolen money were deposited.

Amazon textbook rental service scammed for $1.5m

Michigan man arrested for borrowing costly textbooks and selling them

A 36-year-old man from Portage, Michigan, was arrested on Thursday for allegedly renting thousands of textbooks from Amazon and selling them rather than returning them.

Andrew Birge, US Attorney for the Western District of Michigan, said Geoffrey Mark Hays Talsma has been indicted on charges of mail and wire fraud, transporting stolen property across state lines, aggravated identity theft, and lying to the FBI.

Also indicted were three alleged co-conspirators: Gregory Mark Gleesing, 43, and Lovedeep Singh Dhanoa, 25, both from Portage, Michigan, and Paul Steven Larson, 32, from Kalamazoo, Michigan

Computer scientists at University of Edinburgh contemplate courses without 'Alice' and 'Bob'

Academics advised to consider excluding certain terminology for the sake of inclusivity

A working group in the School of Informatics at the University of Edinburgh in Scotland has proposed a series of steps to "decolonize" the Informatics curriculum, which includes trying "to avoid using predominantly Western names such as Alice/Bob (as is common in the computer security literature)."

The names Alice and Bob were used to represent two users of a public key cryptography system, described in a 1978 paper by Ronald Rivest, Adi Shamir, and Leonard Adleman, "A Method for Obtaining Digital Signatures and Public-Key Cryptosystems." And since then, a variety of other mostly Western names like Eve – playing an eavesdropper intercepting communications – have been employed to illustrate computer security scenarios in related academic papers.

The School of Informatics' working group reflects the University of Edinburgh's commitment to diversity, equity, and inclusion and to meet specific obligations spelled out in Scottish regulations like the Equality Act 2010 and the Public Sector Equalities Duty.

Toyota needs more than its Cheer Squad to deal with chip shortages, as five more home factories forced into idleness

Car makers facing increasingly tough times until supply catches up

Toyota said it would cut car production by up to 150,000 vehicles due to ongoing semiconductor shortages and restrictions associated with the COVID-19 pandemic.

The car maker is idling five factories in home country Japan on some days in November, which affects the production of popular models including Corolla and Camry.

Toyota started cutting production in August due to chip shortages and said, "we expect the shortage of semiconductors to continue in the long-term".

Missouri governor demands prosecution of reporter for 'decoding HTML source code' and reporting a data breach

Salus populi suprema lex esto ... or perhaps not

A Missouri politician has been relentlessly mocked on Twitter after demanding the prosecution of a journalist who found and responsibly reported a vulnerability in a state website.

Mike Parson, governor of Missouri, described reporters for local newspaper the St Louis Post Dispatch (SLPD) as "hackers" after they discovered a web app for the state's Department of Elementary and Secondary Education was leaking teachers' private information.

Around 100,000 social security numbers were able to be exposed when the web app was loaded in a user's browser. The public-facing app was intended to be used by local schools to check teachers' professional registration status. So users could tell between different teachers of the same name, it would accept the last four digits of a teacher's social security number as a valid search string.

Everyone who wants a smartphone for Chrimbo will get one, but in the real world things are somewhat different

Global handset market slips in Q3 on sliding chipset availability, says Canalys

Crippling component shortages caused smartphone shipments to dip in calendar Q3, though it was the also-rans, vendors outside of the top five biggest brands with the lowest economies of scale, that suffered most.

Preliminary results from Canalys show the market declined 6 per cent year-on-year. The analyst was not yet ready to make public the absolute shipment figures but a year ago sales into the channel were 348 million, so they look 20.9 million units lighter.

"The chipset famine has truly arrived," said Ben Stanton, principal analyst. "On the supply side, chipset manufacturers are increasing prices to disincentivize over-ordering, in an attempt to close the gap between supply and demand. But despite this, shortages will last until well into 2022."

Boeing 737 Max chief technical pilot charged with deceiving US aviation regulators over MCAS

He hasn't got $2.5bn to hand to the DoJ, unlike his bosses

A Boeing 737 Max test pilot has been charged with obstructing US aviation safety regulators, according to the US Department of Justice, and faces up to 20 years in prison if convicted.

Former 737 Max chief technical pilot Mark Forkner, 49, of Texas, has been charged with "deceiving the Federal Aviation Administration's Aircraft Evaluation Group" (AEG) and committing fraud by misleading Boeing's airline customers into believing the 737 Max was a safe aircraft.

"Forkner allegedly abused his position of trust by intentionally withholding critical information about MCAS during the FAA evaluation and certification of the 737 MAX and from Boeing's US-based airline customers," said Assistant Attorney General Kenneth A Polite Jr of the Justice Department's Criminal Division in a statement.

Keep expectations low and you won't be disappointed: OVH manages 6 per cent increase on its IPO debut

French cloud provider puts outage and fire behind it to focus on beating the big players

French cloud and colocation service provider OVH has edged a 6 per cent increase in its nominal market valuation following its initial public offering on the Euronext Paris stock exchange.

The Gallic tech challenger, viewed by some as the great cloud hope for Europe, has faced its fair share of challenges this year, having seen fire engulf its Strasbourg operations on 10 March.

But the European IPO proved hot in other ways, with shares up to around €19.70, well on track with the launch price range of €18.50-€20.

Space boffins: Exoplanet survived hydrogen-death of its host star

Hope extended to gas giants across the universe... well, it is Friday

Those of us fatalistically counting down the minutes until the Earth is engulfed by the dying embers of the Sun in approximately 5 billion years might be offered a glimmer of hope by the news that planets – or at least gas giants – can survive the collapse of their host star.

Joshua Blackman, a postdoctoral researcher at Australia's University of Tasmania, and his colleagues have found evidence of a Jupiter-like planet orbiting a white dwarf star somewhere outside the Solar System off in the Milky Way.

It is the first time scientific evidence of a planet surviving a star's collapse has been presented, although theoretical models predicted it is possible, according to a study published in Nature.
