The worldwide DRAM market saw a 9% decline in output value during the second quarter, compared with the first three months of 2019, and the market for NAND flash memory devices was unchanged from Q1, DRAMeXchange reports. Samsung Electronics and SK Hynix increased their share in the NAND flash market in Q2, together commanding 45.2% in market share.
The vast amount of data produced by autonomous vehicles and other products will, in the near future, require dramatic advances in semiconductor technology, Navin Chaddha of Mayfield Fund writes. "I predict that over the next few years we will see a flowering of new silicon architectures and designs that are built and optimized for specialized functions, including data intensity, the performance needs of artificial intelligence and machine learning and the low-power needs of so-called edge computing devices," he notes.
Nvidia reported revenue of $2.58 billion in the second quarter, off by 17% from a year earlier, yet higher than the $2.55 billion in average analyst estimates, per IBES data from Refinitiv. The chip design company forecast third-quarter revenue of about $2.9 billion, lower than average analyst estimates of $2.97 billion.
Diodes brought out the AP3917 line of non-isolated buck power switchers, meant for such low-power applications as internet of things endpoints and small appliances. There are three devices -- the AP3917B, AP3917C and AP3917D.
While NVMe flash memory technology is now qualified as enterprise-class storage, Intel's Optane and other emerging memory types have yet to qualify as storage-class memory, according to attendees of last week's Flash Memory Summit conference in Silicon Valley. Dell EMC, Hewlett Packard Enterprise, IBM, NetApp and Pure Storage are selling NVMe flash arrays.
Radio-frequency components for 5G applications may be suitable for gallium nitride process technology, as an alternative to silicon-based microchips, this analysis notes. Ajit Paranjpe of Veeco says, "Today, GaN is slowly replacing silicon in specific applications, such as the RF amplifier front-end of 4G/LTE base stations."
Samsung Electronics and AT&T have a pilot project in Austin, Texas, to see how 5G cellular communications may help to improve the semiconductor manufacturing process. "We see 5G being a great solution for solving a lot of the Wi-Fi issues that typical factories have today," said Andre Fuetsch of AT&T Communications.
Microcontroller sales have declined this year due to market weakness in electronic systems, the worldwide automotive slowdown and the US-China trade war, IC Insights notes. The market research firm forecasts MCU sales will increase 3.2% next year to around $17.1 billion.
Micron Technology has created 600 new jobs this year with the expansion of its semiconductor manufacturing operations in Singapore. The memory chipmaker plans to add another 1,500 positions at the wafer fabrication facility in the near future.
Researchers at the UK's University of Warwick came up with a cheaper and greener way to pattern metals for electronics going into solar panels. The method involves thermal evaporation and organofluorine compounds while using continuous roll-to-roll processing.
