Monday, 12 February 2007 |
Programmable accelerators combine the performance of custom hardware with the flexibility of software--and they are surprisingly easy to design. This article shows how to specify, profile, and debug a programmable accelerator, all in a matter of weeks. Higher product design costs and risks have been driving the electronics industry to an increased focus on developing "product platforms." The architecture often needs to be able to support new product requirements over the lifetime of the platform without a chip re-spin....more  (0) Comments |
Chip Makers Report High-k Breakthroughs |

Three entities--IBM, Intel and Sematech--have separately disclosed breakthroughs in the development of high-k dielectrics and metal gates for use in advanced gate stack applications in logic designs. Intel has disclosed more details about its 45-nanometer process, saying that it has implemented two materials--high-k dielectrics and metal gates--for the technology. The company claims to be one of the first chip makers to implement the new materials in transistor development. High-k dielectric films are expected to replace silicon dioxide for gate stack applications in logic designs at 45-nm and finer process nodes. Metal gates are supposed to replace the polysilicon used in those applications....more (0) Comments |

The DRAM market has crashed — at least temporarily — as average selling prices (ASPs) have already fallen by 30 percent since the beginning of this year.
DRAM prices were projected to fall by 31.3 percent for the entire year of 2007, but ASPs have fallen by that much alone since January, said Brian Shieh, president of Powerchip Semiconductor Corp., a Taiwan supplier of memories. Poor demand and seasonal factors prompted the DRAM crash, causing vendors to cut prices at an alarming rate. On the spot market, ASPs were down by an average of 4.8 percent across all densities for the week ended Feb. 2, standing at $4.90 on a 512-Mbit equivalent basis, according to Gartner Inc. That is the first time ASPs have fallen below the $5 level in the past six months, according to the research firm....more (0) Comments |

Plummeting Prices Make NAND Flash "Almost Free" |

Prices for NAND Flash memory chips are projected to crater this year, tumbling by a whopping 65 percent and prompting whispers that this once high-margin technology could soon become a nearly free commodity. NAND was in a state of severe oversupply throughout 2006, and the problems have apparently spilled over into 2007. Starting late last year, poor seasonal demand prompted Samsung, Hynix and others to dump 8-Gbit NAND parts in the spot market. This sent average selling prices (ASPs) plummeting in January, and caused the apparent collapse of the contract market, analysts said. The bad news for NAND manufacturers, however, opens new doors for system OEMs. With NAND prices having sunk so low, system vendors can either pack more memory into enhanced products at the same price points or slash prices on products with current memory capacity, said Rob Enderle, president and principal analyst of the Enderle Group (San Jose)....more (0) Comments |

Intel and IBM have been showing off their wares as 45-nm hafnium chips roll through their fabs. “We have had high-k oxide and metal gates moved into 300mm wafer in a production fab for more than a year,” said Dr. Ghavam Shahidi, IBM director of silicon research. “Our target is to have it in production in 2008.”...more (0) Comments |

OLED technology is rapidly evolving, and these improvements are changing the dynamics in display selection. Currently the dominant technologies used for graphic user interfaces are LCDs, with VFDs used in some applications. Emissive displays such as OLEDs and VFDs have advantages in the areas of ease of readability from any angle, and high legibility, but until now OLEDs have had disadvantages in the areas of product availability and lifetime. Where early OLED models were targeted towards MP3 and mobile phone subdisplays with typically less than 2-in. screen diagonals, this year will see standard OLED products measuring from 4 to 5 in. in diagonal offered by manufacturers, opening up a whole range of new applications for OLED displays....more (0) Comments |
