Intel provided details of its spin-transfer torque magnetoresistive random-access memory technology at last week's International Electron Devices Meeting in San Francisco, saying the nonvolatile memory is "production-ready" for its 22FFL process. Samsung Electronics unveiled its STT-MRAM, which it will fabricate with a 28-nanometer fully depleted silicon-on-insulator platform.
MediaTek posted November consolidated revenues of $604.2 million, down 10.4% from October, while consolidated sales for the first 11 months of the year were off by 1.3% from a year ago. Taiwan-based firms providing backend services report orders from MediaTek are down about 10% in the fourth quarter, compared with the third quarter, although those backend houses expect to see their MediaTek-related business rebound next month, industry sources say.
Imec reports being able to produce 3D stacked FinFETs on 300-millimeter wafers with a sequential integration approach that uses a 45-nanometer fin pitch and 110nm poly pitch technology. Junction-less devices on the top layer of the substrate are made at a temperatures of less than 525 degrees C in a silicon layer transferred through wafer-to-wafer bonding, imec says.
IBM collaborated with Nvidia on developing the IBM Spectrum AI with Nvidia DGX system, a converged data storage offering that is optimized with artificial intelligence technology. The system is meant for AI workloads and can use such data tools as TensorFlow, Spark and PyTorch.
The concept of printed electronics has been in research and development for years, and that work is finally paying off on multiple fronts, this analysis notes. "Anytime you need a flexible form factor that can be adjusted to fit a particular shape, this works great," said Dan Brewer of Brewer Science.
Arm's predictions for the internet of things in the new year include the mainstreaming of home automation, personalized delivery and improved health care service. The company also commissioned a survey of 2,000 consumers by NorthStar, getting their opinions about 5G, artificial intelligence, IoT and machine learning.
Taiwan's Intellectual Property Court denied two applications for preliminary injunctions against Novatek Microelectronics submitted by a competitor, FocalTech Electronics. FocalTech claimed that Novatek's NT36672 and NT36525 chips, known as touch controllers with display driver integration mostly used in smartphones, infringed a patent held by FocalTech.
November consolidated revenues for both Taiwan Semiconductor Manufacturing Co. and United Microelectronics were slightly down from October, while Vanguard International Semiconductor posted a monthly gain of 2.4%. On a year-to-year basis, TSMC's November revenues increased 5.6% to $3.19 billion.
Researchers in the US report the potential development of room-temperature fluorine-ion batteries using a liquid electrolyte discovered at the Jet Propulsion Laboratory. The research team ran computer simulations on the anion-based rechargeable battery, which they say could be an alternative to lithium-ion batteries.
Imec reports that spin-transfer torque magnetoresistive random-access memories now favorably compare with static RAMs for last-level caches used in high-performance computing. The research institution also found that STT-MRAMs offer significant energy gains compared with SRAMs.
