Samsung Introduces 0.6mm-Thick Flash Chips for Mobile Devices

Pulkit Chandna — Fri, 06 Nov 2009 18:23:03 -0600

Samsung has announced a new breakthrough that could lead to mobile devices with greater storage space than before. The company says it has developed a new multi-chip memory package that is 40% thinner and lighter than a normal memory package. The 0.6mm-thick package is said to contain eight 30-nanometer NAND Flash chips.

The new package owes its lean figure to a “bare” die that is just half as thick as a conventional die. The ultra-thin package contains a “bare” die that is only 15 micrometers thick. This is quite an achievement on Samsung’s part as it has managed to overcome “the conventional technology limits of a chip's resistance to external pressure when under 30um in height.” Chips based on this new technology seem tailor-made for SSDs and mobile devices.

Micron Manufacturing Two New High-Performance NAND Flash Devices

Bart Salisbury — Mon, 19 Oct 2009 15:54:48 -0500

Micron Technology has announced two new enterprise NAND flash memory chips: a 16Gb single-level cell (SLC) NAND and a 32Gb multi-level (MLC) cell NAND, both produced on a 34nm die. NAND chips are commonplace in flash memory cards and electronic devices with built-in flash memory.

Micron reports that the two new chips can achieve up to 30,000 write cycles, a six-fold increase over present technology. Furthermore, the chips will support the Open NAND Flash Interface (ONFI) 2.1 synchronous interface, which can deliver a 4x to 5x improvement in data transfer rates over legacy NAND interfaces. Improved throughput specifications and smaller size hold promise for expanding flash memory options for consumers.

Micron’s new NAND chips are currently being tested with customers and controller manufacturers. Volume production of the chips is expected to begin early in 2010.

Samsung Confirms Slow Write Problems with 32nm Flash Memory

Ryan Whitwam — Fri, 02 Oct 2009 20:44:42 -0500

In recent days, several SSD manufacturers have made it known that they wanted nothing to do with Samsung’s new 32nm NAND Flash chips. Now Samsung is coming clean and admitting to the issues. The new chips suffer from unacceptably slow write speeds, and are therefore not suitable for use in SSDs. It seems the problem lies mainly with the chips interaction with existing flash controllers.

According to Samsung, "… for quality SSDs, every NAND process geometry upgrade requires a matching upgraded controller. Should (Samsung's) 30nm-class NAND be used with a conventional controller of insufficient quality, performance slowdowns are indeed possible."

NAND flash memory uses floating-gate transistors to create arrays of memory cells. As these arrays scale to smaller and smaller sizes, errors will accumulate faster. Error Correcting Code (ECC) on the controller is used to correct these issues. If an insufficiently powerful controller is used, the memory may become corrupted. Samsung is currently working on its own flash controller to pair with the 32nm NAND chips. In the meantime, don’t expect SSD price drops for at least several months.

New SSD Firmware from OCZ, Indilinx Improves Idle Performance

Paul Lilly — Mon, 10 Aug 2009 09:16:54 -0500

We've longed bemoaned the real-world write performance of most SSDs, which often falls short of the much speedier read speeds. Even worse, surmises HotHardware, is the potential for an SSD's write performance to degrade over time.

"The flash memory used on today's SSDs is comprised of cells that usually contain 4KB pages that are arranged in blocks of 512KB," writes HotHardware. "When a cell is unused, data can be written to it relatively quickly. But if a cell already contains some data -- no matter how little, even if it fills only a single page in the block -- the entire block must be re-written. That means, whatever data is already present in the block must be read, then it must be combined or replaced, etc., with the new additional data, and the entire block is then re-written."

The good news is most manufacturers are attacking the problem head on via firmware. One such example is OCZ's implementation of the Indilinx firmware, which the company plans to include on all Vertex series drives. When the drives are idle, Indilinx and other similar SSD firmware sweep through an SSD's cells looking for and removing so-called "garbage data."

HotHardware got its hands on one of OCZ's new Vertex drives outfitted with the Indilinx firmware and the results are pretty surprising. After "dirtying" the drive with chunks of data, performance degradation became apparent while running the ATTO Disk Benchmark. But after letting the drive sit idle for 5 minutes, performance numbers were nearly restored to new condition.

Samsung Launches 32GB NAND Flash Memory Card

Andy Salisbury — Wed, 13 May 2009 16:37:11 -0500

Yesterday Samsung announced that shipments of their 32GB moviNAND flash memory cards had begun.

The cards are currently aimed at cell phones, media players and other consumer electronics, and have been made using a 30nm manufacturing process. This allows them to process and store large amounts of multimedia, including videos, video games and television shows.

“The unquenchable consumer thirst for possessing large amounts of data is now embracing video in a big way, which in turn means rapidly escalating demand for higher density storage,” stated Jim Elliott, Samsung’s Vice President of Memory Marketing. “Samsung has taken the lead in providing OEMs with the highest density flash storage produced using the most cost-efficient process technology around – 30 nanometers.”

Reportedly, Samsung’s exports of cards will grow eight-fold “from 120 million 16GB equivalent units, which will account for 13 percent of the global memory card shipments in 2009, to 950 million units – or 72 percent of the total cards shipped – by 2013.”

NAND Supplies Could Come Under Strain after Apple's Huge Order

Pulkit Chandna — Mon, 13 Apr 2009 20:21:39 -0500

Apple is reported to have put NAND flash supplies under considerable strain by placing an order for 100 million 8Gb NAND flash chips with Samsung Electronics.

Taiwanese website Digitimes was the first to report on the issue. Sources told Digitimes that NAND supply will remain sparse until the end of May. NAND prices are expected to continue their upward trend on the back of this huge order. This is because NAND flash chip manufacturers are not keen on increasing production.

According to Daniel Amir, an analyst with Lazard Market Capital, Apple’s gargantuan order comprises both 16Gb and 8Gb NAND flash chips. Amir believes Apple’s order for 16Gb NAND is a harbinger of 32GB iPhones being around the corner. The same analyst had reported last month that industry insiders had told him that 32GB iPhones would become available in June, 2009.

Intel Ups The SSD Ante With 32GB, 32nm Flash Chips

Andy Salisbury — Tue, 25 Nov 2008 14:08:12 -0600

Intel and their memory-producing partner, Micron, have recently started mass-producing the first of their 34nm NAND flash memory. The smaller chips allow the two companies behind them to make single chip layers with 4GB of storage. This paves the way for two layer stacks that can hold as many as 64GB.

This new and improved flash memory is currently being aimed at portable electronics such as cell phones or MP3 players. What’s even better, is the possibility of a substantial increase in size of solid-state drives! And it shouldn’t be too far off, either. Thanks to their speedy manufacturing they’re currently looking to implement the first wave of chips in early 2009.

It’s expected that one of the first companies to take advantage of the tiny chips is Apple, who has been stuck at a 32GB storage ceiling on the popular iPhone and iPod touch.

DSLR Compact Flash Users, Get Into the SD/SDHC (and Eye-Fi) Game with CFMulti

Mark Edward Soper — Mon, 20 Oct 2008 15:32:52 -0500

If you're a Compact Flash user, life's not been fair to you lately. You've seen CF stalwarts like Nikon and Canon turn their backs on this longtime favorite in favor of the new kid on the block, SDHC, in their newest DSLRs. Buy a new camera, and you make your collection of CF cards obsolete. Meanwhile, you've watched SDHC and its kid brother, SD, dominate the deals in your favorite big-box electronics superstores' weekly tabloids. And, just to add a cherry on the top of your cake of frustration, you've been thinking about how cool it would be to use wireless file transfer with Eye-Fi cards, but Eye-Fi is also in the tank for SD. Oh, and did I mention that "Compact" Flash is now the bulkiest flash memory format?

For all these reasons, Synchrotech's introduction of the CFMulti CompactFlash Type II to Eye-Fi + Multi-Card Adapter has come at a very good time. While CF adapters for SD cards have been around for awhile, the CFMulti also supports newer flavors such as SDHC and MMC+ as well as SD and any old MultiMediaCards (MMC) you have floating around. Plus, it's the first adapter to support Eye-Fi cards, albeit with a reduction in range. See the CFMulti and Eye-Fi FAQ for details and a list of tested cameras.

In addition to enabling some CF-based cameras to use Eye-Fi cards, this adapter will be helpful to users of Nikon and Canon DSLRs that use a mixture of CF and SD/SDHC cards. At $28.00, it takes some of the sting out of making the move from CF-based cameras such as the Canon Rebel XTi or Nikon D70 to SD/SDHC-based cameras like the Canon Rebel XSi, Rebel XS or Nikon D90. You can still use high-speed UDMA Compact Flash cards when you need the absolute best speed on your CF-based cameras, but you can now take advantage of numerous deals on easier-to-tote SD and SDHC cards. Sweet!
