(InfoWorld) - Flash memory and hard-disk drives could face a challenge from a new chip technology, dubbed phase-change memory, being developed by a group of companies led by IBM. The companies on Monday announced the results of their latest research into the technology, which they say will do a better job of storing songs, pictures, and other data on iPods and digital cameras than current flash memory, and could someday replace disk drives. Among the advances, the companies have built a prototype device that runs 500 times faster than today's flash memory while using half as much power to write data to a memory cell, they said. The circuits on the device are much smaller than those on today's flash chips, measuring just 3 by 20 nanometers, and show that, unlike flash, phase-change memory will be suitable for production on the advanced manufacturing techniques targeted for use in 2015, the companies said. A nanometer is a billionth of a meter. The progress came partly from the development of a new material to build the memory chips, a germanium alloy to which the researchers added other elements to enhance its properties. The companies have applied for a patent for the material, they said. Besides IBM, the developers include Qimonda, the DRAM spin-off from Infineon Technologies, and Taiwan's Macronix International Co. They plan to discuss their findings at the Institute of Electronics and Electrical Engineer's 2006 International Electron Devices Meeting in San Francisco later this week. It's the kind of breakthrough that people look forward to in the IT industry, although end users will have to be patient before it finds its way into products. It could take several more years for the technology to be developed sufficiently for use in finished products. Still, phase-change memory appears promising. The chips would be a new type of non-volatile memory, which is memory that can hold its electrical charge -- and its data -- after devices are turned off. Flash is also non-volatile, but phase-change memory can hold its electrical charge better than flash and use it more efficiently, its backers say. Flash also faces a roadblock in the future. As engineers make chip circuits more tiny, the circuits leak more power and ultimately lose their ability to store data after being turned off. The size limit appears to be around 45nm, although it will still be years before the flash industry starts using such tiny production technologies. Phase-change memory can be scaled down to 22nm, or far smaller than flash memory, the researchers developing it say. It also appears able to be more durable than flash, whose memory cells start to break down after 100,000 rewrites. While its prospects appear bright, the technology faces several hurdles. New chip designs must be relatively easy to manufacture, and they need to be cost-effective enough to attract device makers. RambusÂ faced this issue when its chips failed to overtake DRAM as the main memory type for PCs several years ago, despite having the backing of Intel. The problem, some companies said, is that the chips was were too costly to produce -- although Rambus vehemently disagrees with this. IBM has posted photos of the phase-change devices here, and some animation clips here.

EMC plans to introduce a line of solid-state drives using flash memory as an option to replace some disk drives in the company&#39;s high-end Symmetrix storage arrays, a company spokesman said Monday.EMC will offer solid-state drives with capacities of 73GB and 146GB, said Abhrajit Bhattacharjee, an EMC spokesman in Singapore. The drives, which will ship this quarter, will only be available as an option with Symmetrix storage arrays, and will not be available with other products, he said.Pricing for the solid-state drives&#160;was not immediately available, but using four 73GB solid-state drives to replace four of the 146GB hard disk drives in a Symmetrix 100-disk array would increase the cost by less than 10 percent compared to a comparable system using only hard disk drives, Bhattacharjee said.Solid-state drives use memory chips instead of magnetic platters to store information. These types of drives are generally faster and consume less power than traditional disk drives, but they are also significantly more expensive.The solid-state drives are aimed at customers willing to pay a premium for the significantly faster response times these drives offer, Bhattacharjee said.EMC plans to use single-cell flash memory in its solid-state drives, which will allow for higher performance but costs more than multicell flash memory.Single-cell flash memory stores one bit of information in each memory cell, while multicell flash memory stores two. The greater density of multicell flash makes it perfect for music players and digital cameras. But multicell flash is significantly slower, making single-cell flash more suitable for high-performance applications such as solid-state drives. Single-cell flash memory is also more durable that multicell flash. Each cell on a multicell flash chip is generally good for 10,000 write/erase cycles, while the cells on single-cell chips can last for 100,000 write/erase cycles. The durability of a flash memory chip can be increased with the use of wear leveling, a technique that writes data equally to all of the memory cells on a chip instead of using the same cells repeatedly.Drives based on magnetic platters are capable of enduring unlimited write/erase cycles, but they have moving parts which can break down. Solid-state drives do not have moving parts.STEC -- the maker of the solid-state drives that EMC plans to offer -- said its solid-state drives, which use wear leveling, last more than 2 million write/erase cycles. There was no indication of how many write/erase cycles the EMC solid-state drives will be capable of sustaining.

(InfoWorld) - Samsung Electronics showed off its first 40-nanometer chip, a 32Gb NAND flash memory that can be used in memory cards able to store up to 64GB of data, or 40 movies. The latest step into smaller chip manufacturing methods brings Samsung to the forefront of chip production putting it ahead of other bit manufacturers, including Intel, which has onlyÂ announced chips built at 45nm. The chips are also the seventh generation of NAND flash memory to follow in a Moore's law-type theory posited by Samsung, that the company will double the capacity of NAND flash every 12 months. Such advances are vitalÂ to the consumer electronics industry. Users are demanding ever smaller devices that can do more, such as handsets with built-in mobile phone, computing, camera, and digital music playing functions. Demand for more storage to keep photos, videos, songs and other data has expanded rapidly over the past few years, and analysts expect the trend to continue. The 40nm chip production technique is key to making chips smaller, faster, more powerful, and cheaper to produce. A nanometer is a billionth of a meter, and the measurement is a guide to the size of the transistors and other parts that are etched onto the chips. Typically, the more transistors, and the closer they are together, the faster the chip can perform tasks. The company also revealed a new design technique, Charge Trap Flash (CTF), that will allow it to eventually shrink NAND chip features to 20nm, and produce 256Gb chips. In the 32Gb chips, the control gate in the CTF is only a fifth as big as conventional control gates on chips in a typical floating gate structure. With CTF, there is no floating gate. Instead, data is temporarily placed in a holding chamber made of silicon nitride. Samsung also released a new chip for its hybrid drives, a kind of hard disk drive aimed at laptops that uses NAND flash as a disk cache, to speed boot-up times and reduce power consumption The new chip, dubbed an SoC (system-on-chip) because it does the work of several chips, incorporates up to 4GB of NAND flash as a data buffer and helps further speeds boot-up times while lengthening battery life, the company said. The chips will be in mass production in November. Samsung is one of several companies working on hybrid drives. Seagate TechnologyÂ and IntelÂ are also developing the technology for notebook computers.
