Comments Off on New USB Chip Developed
Silicon Motion says it has begun shipping samples of a new USB 3.0 controller chip for flash drives that could boost performance by up to 50%.
The company said the new SM3267 integrated controller is expected to deliver up to 160MB/s read, and 60MB/s write speeds through a single channel; that would be a 30% to 50% performance improvement over today’s USB 3.0 flash drive technology.
Even though the USB 3.0 specification has the capability to support 4.8Gbps throughput speeds, the speed of a USB 3.0-enabled flash drive is dictated by the speed of the accessing flash devices in the drive. Today, most consumer-USB 3.0 flash drives support about 100MB/s read speeds.
We are pleased to announce that SM3267 has received design-ins from most of our current USB controller customers, including many top-tier OEMs, and we expect SM3267-based USB 3.0 flash drives will be commercially available starting in the fourth quarter of 2013,” Wallace Kou, CEO of Silicon Motion, said in a statement.
The new integrated chip will also be able to run at lower voltages, from 5 volts to 1.2 volts, enabling a 25% to 30% lower USB flash drive device temperature compared with other USB 3.0 flash controller products in the market, Silicon Motion said.
The new IC will support the vast majority of NAND flash technology, including new triple-level cell (TLC), multi-level cell (MLC), high speed Toggle, and ONFI DDR NAND manufactured by Samsung, Toshiba, SanDisk, SK Hynix, Micron and Intel.
The new chip has already passed both USB-IF compliance testing and WHCK (Windows Hardware Certification Kit) tests for Windows 7 and Windows 8.
The new IC is available in a Chip-on-Board (COB) and in a 48-pin QFN green package.
Stanford Develops Carbon Nanotubes
Researchers at Stanford University have demonstrated the first functional computer constructed using only carbon nanotube transistors.
Scientists have been experimenting with transistors based on carbon nanotubes, or CNTs, as substitutes for silicon transistors, which may soon hit their physical limits.
The rudimentary CNT computer is said to run a simple operating system capable of multitasking, according to a synopsis of an article published in the journal Nature.
Made of 178 transistors, each containing between 10 and 200 carbon nanotubes, the computer can do four tasks summarized as instruction fetch, data fetch, arithmetic operation and write-back, and run two different programs concurrently.
The research team was led by Stanford professors Subhasish Mitra and H.S. Philip Wong.
“People have been talking about a new era of carbon nanotube electronics moving beyond silicon,” Mitra said in a statement. “But there have been few demonstrations of complete digital systems using [the] technology. Here is the proof.”
IBM last October said its scientists had placed more than 10,000 transistors made of nano-size tubes of carbon on a single chip. Previous efforts had yielded chips with just a few hundred carbon nanotubes.
Micron Ships Hybrid Memory Cube
Micron Technology has announced that is is currently shipping 2GB Hybrid Memory Cube (HMC) engineering samples that represent a dramatic step forward in memory technology and are designed for applications that require high-bandwidth access to memory like data processing, data packet buffering or storage.
According to Micron, the Hybrid Memory Cube uses advanced through-silicon vias (TSVs)-vertical conduit that connect a stack of individual chips in order to combine high-performance logic with Micron’s DRAM. The current engineering sample features a 2GB memory cube that consists of four 4Gb DRAM dies. It provides 160GB/s of memory bandwidth while using up to 70 percent less energy per bit when compared to currently available technologies.
Micron expects 4GB HMC engineering samples to be available in early 2014 while volume production of both 2GB and 4GB HMC is scheduled to begin later in 2014.

Comments Off on HP To Support The iPad
Is your iPad out of warranty? Hewlett-Packard to the rescue.
HP updated its SmartFriend support service and will now troubleshoot problems with Windows, Android, Chrome OS, OS X and iOS products, according to a fact sheet describing the service.
“HP is expanding its HP SmartFriend service to provide 1:1 expert support for any brand of PC or tablet,” the company said. The plan previously supported PCs from HP and other vendors, as well as Macs.
Users can avail of the service to address general hardware, software and malware issues. HP says its agents can “remove viruses, improve PC performance, solve software errors, and connect devices to a wireless network with enhanced security.” The support is provided by phone or over the Internet, so don’t expect a technician to trot in and fix your iPad in person. But HP notes it can save you from driving to a store.
Unlike Best Buy’s Geek Squad service, HP’s service does not include hardware repairs. It can be tricky to change the battery or storage in tablets, so for iPads, the Genius Bars at Apple Stores may still be the best option for some repairs.
HP didn’t immediately comment on exactly what support it will provide for the iPad. HP printers offer wireless printing from iPads and iPhones. HP sells primarily Windows PCs and Android tablets, though on last Thursday it announced the Pavilion 14 laptop with Google’s Chrome OS.
While SmartFriend includes support for iOS devices, the service seems focused mainly on Windows products. Its technicians include “Microsoft Application Trainers, Microsoft Product Specialists, A+/MCP/MCSE Certified Professionals, Network Administrators and HTML Developers,” according to the fact sheet.
The service starts at US$9.99 per month and users can sign up for a pre-paid, monthly or yearly support plan. A “Complete Plan” supports two devices, while a “Family Plan” supports up to four devices.
Dell Bets On Windows 8
Demand for Windows 8 may be still somewhat lukewarm, but Dell is maintaining its stance that it is the best operating system for business tablets and plans to roll out more Windows 8-based products later this year, according to a senior executive at the computer maker.
“Our Windows tablets are more secure and easier to manage than Android-based products and iOS-based products [because Windows is] on our tablets,” said Jeff Clarke, vice chairman and president of global operations at Dell. “And we are not going to change that.”
Windows-based devices accounted for just 4.5% of tablet sales in this year’s second quarter, according to research firm IDC. In comparison, Android-based devices had 62.6% of the tablet market and Apple’s iPad had 32.5%.
The slow adoption of Windows 8 tablets is partly due to their high prices, and to the operating system’s lack of mobile apps, analysts say. Windows 8 has also received mixed reviews, with some people citing its lack of a Start button in the desktop mode as a major problem.
But Dell expects demand for Windows 8 devices to pick up with the availability of Windows 8.1, which Microsoft will release in October.
Java 6 Security Hole Found
Security firms are urging users of Oracle’s Java 6 software to upgrade to Java 7 as soon as possible to avoid becoming the victims of active cyber attacks.
F-secure senior analyst Timo Hirvonen warned about the exploit this weekend over Twitter, advising that he had found an exploit in the wild actively targeting an unpatched vulnerability in Java 6, named CVE-2013-2463.
PoC for CVE-2013-2463 was released last week, now it’s exploited in the wild. No patch for JRE6… Uninstall or upgrade to JRE7 update 25.
— Timo Hirvonen (@TimoHirvonen) August 26, 2013
CVE-2013-2463 was addressed by Oracle in the June 2013 Critical Patch Update for Java 7. Java 6 has the same vulnerability, as Oracle acknowledged in the update, but since Java 6 became unsupported in April 2013, there is no patch for the Java 6 vulnerability.
Cloud security provider Qualys described the bug as an “implicit zero-day vulnerability”. The firm’s CTO Wolfgang Kandek said he had seen it included in the spreading Neutrino exploit kit threat, which “guarantees that it will find widespread adoption”.
“We know about its existence, but do not have a patch at hand,” Kandek said in a blog post. “This happens each time a software package loses support and we track these instances in Qualysguard with our ‘EOL/Obsolete’ detections, in this case.
“In addition, we still see very high rates of Java 6 installed, a bit over 50 percent, which means many organisations are vulnerable.”
Like F-secure, Kandek recommended that any users with Java 6 upgrade to Java 7 as soon as they can.
“Without doubt, organisations should update to Java 7 where possible, meaning that IT administrators need to verify with their vendors if an upgrade path exists,” he added.
U.S. Cloud Vendors Hurt By NSA
Edward Snowden’s public unveiling of the National Security Agency’s Prism surveillance program could cause U.S. providers of cloud-based services to lose 10% to 20% of the foreign market — a slice of business valued at up to $35 billion.
A new report from the Information Technology & Innovation Foundation (ITIF) concludes that European cloud computing companies, in particular, might successfully exploit users’ fears about the secret data collection program to challenge U.S. leadership in the hosted services business.
Daniel Castro, author of the report, acknowledges that the conclusions are based, so far, on thin data, but nonetheless argues that the risks to U.S. cloud vendors are real.
Indeed, a month prior, the Cloud Security Alliance reported that in a survey of 207 officials of non-U.S. companies, 10% of the respondents said that they had canceled contracts with U.S. service providers after Snowden’s leak of NSA Prism documents earlier this year.
“If U.S. companies lose market share in the short term, it will have long-term implications on their competitive advantage in this new industry,” said Castro in the ITIF report. “Rival countries have noted this opportunity and will try to exploit it.”
To counter such efforts, the U.S. must challenge overstated claims about the program by foreign companies and governments, said Jason Weinstein, a partner in the Washington office of law firm Steptoe & Johnson and a former federal prosecutor and deputy assistant attorney general specializing in computer crime.
“There are a lot of reasons to be concerned about just how significant those consequences will be,” Weinstein said. “The effort by European governments and European cloud providers to cloud the truth about data protection in the U.S. was going on well before anyone knew who Edward Snowden was. It just picked up new momentum once the Prism disclosures came out.”
Weinstein contends that European countries have fewer data protection rules than the U.S.
For example, he said that in the U.K. and France, a wiretap to get content can be issued by a government official without court authority, but that can’t happen in the U.S.
“U.S. providers have done nothing other than comply with their legal obligations,” he said. But because of Snowden’s leaks, “they are facing potentially significant economic consequences.”
Gartner analyst Ed Anderson said his firm has yet to see any revenue impact on cloud providers since the Prism disclosures, but added, “I don’t think Prism does U.S. providers any favors, that’s for sure.”
Nonetheless, Anderson added, “I think the reality is [the controversy] is likely to die down over time, and we expect adoption to probably continue on the path that it has been on.”
One reason why U.S. providers may not suffer is because “the alternatives aren’t great if you are a European company looking for a cloud service,” he said.
Google Snubs Privacy

Comments Off on Google Snubs Privacy
Search giant Google has told the British government it is immune to prosecution on privacy issues and it can do what it like. The US Company is accused of illegally snooping on its British customers by bypassing privacy settings on Apple devices, such as iPads, to track their browsing history.
A group of British people took Google to court but the search engine is trying to get the case thrown out. Its argument is that it is not subject to British privacy law because it is based in California. This is the second time that Google has tried to avoid British law by pretending to operate in another country. It has come under fire for failing to pay tax in the UK
Nick Pickles, director of Big Brother Watch, said: ‘It is deeply worrying for a company with millions of British users to be brazenly saying they do not regard themselves bound by UK law. Solicitor Dan Tench, of law firm Olswang, said this was another instance of Google being here when it suits them and not being here when it doesn’t. Ironically when the US ordered Google to stop what it was doing, it forced the search engine to pay a $22.5million to regulators.
There are some indications that Google may not get its way. In July the Information Commissioner’s Office told Google its privacy rules breached UK law so it will be very hard for it to stand up in court and say it didn’t.
Intel Launches 530 Series SSD
Intel’s new SSD 530 series was detailed a while ago, but now it is finally official. Intel has formally announced the new drives in three form factors: mSATA, M.2 and 2.5-inch.
The drives will be available in a wide range of capacities, starting at 80GB, through 120GB, 180GB, 240GB, 360GB and 480GB for 2.5-inch drives. As for M.2 and mSATA drives, they will be available in 80GB, 120GB, 180GB and 360GB capacities.
Intel’s new 530 drives are based on 20nm MLC flash and the brains behind the brawn come from LSI, in the form of the SandForce SF-2281 controller. Although transfer speeds will vary depending on capacity, the fastest 530-series drives will deliver read speeds of up to 540MB/s and write at 490MB/s. As for random performance, they boast 41k IOPS in random read and 80k IOPS in random write.
Intel also says the 530-series is its most power efficient storage product to date, which is hardly surprising, but it is good news for notebook vendors who will use mSATA units.
The DoD May Share Airwaves

Comments Off on The DoD May Share Airwaves
The U.S. Defense Department is proposing to share some of its radio airwaves with private industry, a nod to growing pressure from the wireless industry and the Obama administration that federal agencies ease their control of valuable spectrum.
In a letter released by the Federal Communications Commission on Tuesday, the Department of Defense offers to share the airwaves it now dominates in the slice of frequencies from 1755 megahertz (MHz) to 1780 MHz with spectrum-hungry wireless and Internet companies.
The military would rearrange its systems within that slice of spectrum as well as the 2025-2110 MHz band and compress programs into the 1780-1850 MHz band that it would retain.
The Defense Department uses the airwaves for programs such as pilot training and drone systems and has faced criticism from some in the industry and in Congress for resisting efforts to open those airwaves for commercial use to satisfy growing demands posed by data-hungry gadgets and services.
The Pentagon had pointed to its own need for airwaves as its use of drones and other reliance on wireless technology grows. It also had estimated the process of moving its programs to new frequencies would cost more than $12 billion.
Under the new plan, the Defense Department drops the cost estimate to $3.5 billion by compromising on sharing slices of airwaves without completely clearing any of the spectrum bands.
In the letter, originally sent on July 17 to the National Telecommunications and Information Administration, which oversees federal airwaves, DOD Chief Information Officer Teresa Takai called the proposal “a workable balance to provide access to the 1755-1780 MHz band most desired by the commercial wireless industry while ensuring no loss of critical DoD capabilities.”
The NTIA, in its own letter to the FCC, said it had not had enough time to review the proposal and could not yet endorse it.
The FCC, with NTIA’s help, is preparing for several auctions of airwaves to take place in coming years, including one that would sell off chunks of federally controlled spectrum. They will be the first reshuffling of airwave ownership since 2008.
Congress has required the FCC to auction off the 2155-2180 MHz band by February 2015 and the industry has sought to pair up that slice of spectrum with the valuable 1755-1780 MHz band, arguing it would collect more money. Lawmakers in the House of Representatives have introduced a bill to ensure such pairing.
The FCC has been drafting a notice of proposed rulemaking that would seek public comments on how the FCC should auction those federally owned or already cleared airwaves to the wireless companies and an FCC official said the agency’s notice will address the Pentagon’s new proposal.
President Barack Obama last month directed federal agencies to look for ways eventually to give up or share more of their airwaves with the private sector. This followed his June 2010 call to open up 500 MHz of federal spectrum for commercial use.
