The SD Association announced a new interface for flash memory cards today that triples data transfer speeds.

The faster SD card specification was expected since the group started previewing it in September. But more unusually for the consortium, the SD Association also announced an e-book specification at the Consumer Electronics Show in Las Vegas.

"Our new e-Book application...opens broad consumer access to e-book content, and turns billions of existing SD mobile phones and devices into e-readers," Norm Frentz, chairman of the SD Association, said in a statement. "SD continues to evolve its capabilities to support voracious consumer demand for portable movies, television broadcasts, high-definition home videos, and now full-color books."

It's not yet clear who among e-book reader makers, publishers, or other companies are on board with the new specification, but two partners showing eBook support at CES are Toshiba and Sharp, the association said. Such partnerships will be important to its success, though, and there already are other e-book formats, such as ePub.

But eBook won't live in isolation. "The association plans to support popular external formats like ePublish, CPS, XMDF and ".book" formats in the near future," said SD Association communications director Kevin Schader. And to keep content publishers happy, it's free to use and supports copy protection. … Read more

Lexar Media, one of the premium-brand flash memory card makers, will introduce its first SDXC cards later this quarter with two high-end models geared for professionals, a 64GB card for $500 and a 128GB card for $700.

The 128GB model illustrates the narrowing gap between the SD lineage and a rival format popular among professionals, CompactFlash, which tops out at 64GB for mainstream brands. But while SDXC might be a step ahead in capacity--at least when it comes to announced products--CompactFlash leads in a different domain, data transfer speed.

Each of Lexar's new SDXC cards, with a 133X speed … Read more

A new kind of memory from IBM Labs is promising to revolutionize how much data we can store and how fast we can access it on our mobile and desktop devices.

After spending six years as a theoretical concept, the memory, dubbed Racetrack, finally is a huge step closer to reality. Researchers at IBM have recently confirmed that their theories of the physics behind Racetrack are valid and can be used to develop and manufacture this new type of memory.

This revolutionary type of memory could open up a whole new world for laptops, smartphones, and other mobile devices. Users would be able to store as much as 100 more times data on their portable gadgets, perhaps keeping as many as 500,000 songs or 3,500 full-length movies on one mobile device. And since Racetrack would use considerably less power, a single battery charge could power a device for weeks rather than days or hours.

The new memory is also expected to play a role in desktop computers and servers, allowing them to access more data much faster. In some ways, Racetrack combines the best elements of flash memory and magnetic storage and could prove to be the one technology to someday replace current RAM, Flash RAM, and even conventional disk drives.… Read more

China will soon overtake Japan as the world's second heaviest spender on research and development, according to a report from the Battelle Memorial Institute.

A nonprofit group that conducts scientific research, Battelle published its findings today as part of an article in its R&D Magazine. The article and its full supplementary report (PDF) looked at global R&D spending in general and across six specific segments--Information Technology, Electronics, Life Sciences, Aerospace/Defense/Security, Energy, and Advanced Materials.

Next year, China is expected to spend $153.7 billion on R&D, a big jump from $141.… Read more

In the flash-memory format wars, Secure Digital has vanquished xD Card and Memory Stick. SD, as it's known, is supported by everything from Apple laptops to Panasonic 3D videocameras.

But CompactFlash, a rival flash-card format that prevails in high-end SLRs from Canon, Nikon, and Sony, is holding out. More than that: its backers are developing a high-performance successor. Nikon, Sony, and memory card maker SanDisk have proposed that the CompactFlash Association standardize a sequel that can transfer data at a rate of 500MB per second and reach eventual capacities of 6TB.

"This next-generation format is expected to be … Read more

In items like camera memory cards, flash memory is a ho-hum commodity. But when it comes to building flash directly into a computer, the disruption is probably just beginning.

That's why I find Fusion-io an intriguing company.

Fusion-io builds flash memory onto PCI Express cards that plug into server expansion slots, letting customers move beyond hard drives' physical enclosures and SATA interface. That means data can be written and read faster overall, in part because SATA has worse overhead--in other words, bandwidth that must be used to run the communication protocol rather than for the actual data being read or written.

The Salt Lake City start-up isn't the only PCIe storage maker in the market--Texas Memory Solutions' RamSan-10 and the RamSan-20 and OCZ Technology's Z-Drive products are competitors. But Fusion-io has clout: in addition to sales partnerships with IBM, Dell, and Hewlett-Packard, and more than 50 patent applications filed, it's got an investment from flash memory maker Samsung.

Flash crashes the party For all the change in the computer industry, it's actually pretty rare that a hardware difference comes along that actually is more than an evolutionary tweak to the existing setup.

Flash memory, which has displaced the hard drive in corners of the market such as iPods and high-end laptops and has the potential to do so elsewhere, is one of those changes. It combines the world of conventional computer memory--dynamic random access memory, or DRAM--with the world of hard drives.

DRAM needs a constant supply of electrical power to remember its data, but it can read and write data quickly; hard drives store data even when the power is switched off, and can store much larger amounts of data, but they're relatively slow. Intermediate between the two is flash memory, in terms of data transfer speeds and cost per gigabyte, and like a hard drive it can store data when the computer is switched off.

The first large-scale arrival of flash memory in computers took the form of solid-state drives, or SSDs. They packed flash memory into the type of enclosure that in the past housed a hard drive, and they communicated with the rest of the computer system with the standard hard drive interface, called SATA. Advatages of SSDs include faster data transfer, better ruggedness because of the absence of moving parts, and lower power consumption because the physical platters of hard drives don't need to be rotated all the time. … Read more

Intel's deep commitment to flash memory technology was on display today with two announcements centered on large business customers.

The world's largest chipmaker announced it was a lead investor in a company that makes flash storage more palatable to the enterprise, while Hitachi announced the fruits of joint flash development with Intel aimed at large businesses.

As part of 18 new investments by Intel Capital totaling $77 million, the world's largest chipmaker led a group that invested $32 million in Anobit. The Israel-based company has patented technology that increases the long-term reliability of lower-cost-per-bit flash memory, referred … Read more

Editors' note: This is a guest column. See Larry Downes' bio below.

In "1984," George Orwell's classic dystopian novel, protagonist Winston Smith is a low-level bureaucrat in the Ministry of Truth. His job: to "rectify" old newspaper articles in which Big Brother's predictions or promises turned out to be false. Once the articles are rewritten, the original text--and the truth they represent--is dropped down a pneumatic tube known as a memory hole, "to be devoured by the flames."

The European Commission has recently proposed a real-life version of this fictional device, though … Read more

CNET did not review the Sony Handycam DCR-SX63, but we did review the DCR-SR68, which is very similar.

The main differences between the SX63 and SR68 are storage capacity and type. The SX63 stores video to 16GB of internal flash memory as well as Memory Stick Pro Duo and SD/SDHC/SDXC cards. The SR68 records to an 80GB hard drive, but can store to Memory Stick Pro Duo and SD/SDHC/SDXC cards, too.

The SR68 is slightly bigger and heavier than the SX63, but there are otherwise no differences between the two models. They have the same lens, … Read more
