3D NAND Race Faces Huge Tech And Cost Challenges
By Mark LaPedus - 23 May, 2019 - Comments: 8

Amid the ongoing memory downturn, 3D NAND suppliers continue to race each other to the next technology generations with several challenges and a possible shakeout ahead. Micron, Samsung, SK Hynix and the Toshiba-Western Digital duo are developing 3D NAND products at the next nodes on the roadmap, but the status of two others, Intel and China’s Yangtze Memory Technologies Co. (YMTC), is les... » read more

World’s loudest underwater sound A group of researchers hit tiny jets of water with a high-power X-ray laser, creating a record for the world’s loudest underwater sound. The intensity of the blast resulted in an underwater sound with an intensity greater than 270 decibels (dB). That’s greater than the intensity of a rocket launch or equivalent of creating electrical power for a city o... » read more

Challenges In Making And Testing STT-MRAM
By Mark LaPedus - 07 May, 2019 - Comments: 1

Several chipmakers are ramping up a next-generation memory type called STT-MRAM, but there are still an assortment of manufacturing and test challenges for current and future devices. STT-MRAM, or spin-transfer torque MRAM, is attractive and gaining steam because it combines the attributes of several conventional memory types in a single device. In the works for years, STT-MRAM features the ... » read more

Single-atom catalysts A group of researchers have captured the behavior of a single-atom catalyst, a move that could one day help design more efficient catalysts in systems. A catalyst is a substance that increases the rate of a chemical reaction. In vehicles, for example, platinum is used as a catalyst, which speeds up chemical reactions and cleans exhaust gases. Besides platinum, the indu... » read more
