Samsung Electronics showed off its first 40-nanometer chip, a 32-gigabit 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 announced chips built at only 45 nanometers. The chips are also the seventh generation of NAND flash memory to follow in a Moore\u2019s law-type theory posited by Samsung that the company will double the capacity of NAND flash every 12 months.\n\n\n\n\n\n\n\n\n\nSamsung 40nm NANDSuch advances are vital 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 40-nanometer 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 20 nanometers, and produce 256-gigabit chips. In the 32-gigabit 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 a 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 speed 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 Technology and Intel are also developing the technology for notebook computers.-Dan Nystedt, IDG News Service (Taipei Bureau)Related Link:\n\nChartered, Samsung, IBM Prep Next-Gen 45-NM ChipsCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
