Process Control For Next-Generation Memories


The Internet of Things (IoT), Big Data and Artificial Intelligence (AI) are driving the need for higher speeds and more power-efficient computing. The industry is responding by bringing new memory technologies to the marketplace. Three new types of memory in particular—MRAM (magnetic random access memory), PCRAM (phase change RAM) and ReRAM (resistive RAM)—are emerging as leading candidat... » read more

Will In-Memory Processing Work?


The cost associated with moving data in and out of memory is becoming prohibitive, both in terms of performance and power, and it is being made worse by the data locality in algorithms, which limits the effectiveness of cache. The result is the first serious assault on the von Neumann architecture, which for a computer was simple, scalable and modular. It separated the notion of a computatio... » read more

Week In Review: Manufacturing, Test


Fab tools and materials Applied Materials has signed a definitive agreement to acquire Kokusai Electric for $2.2 billion in cash from investment firm KKR. With the acquisition of Kokusai’s semiconductor equipment unit, Applied expands its customer base and gains a foothold in the batch processing equipment business, where a tool can process wafers in parallel. Applied’s strength is in the ... » read more

Accurate Error Bit Mode Analysis Of STT-MRAM Chip With A Novel Current Measurement Module


Authors: (Advantest) Ryo Tamura, Ibuki Mori Naoyoshi Watanabe; (Tohoku University) Hiroki Koike, Tetsuo Endoh. A novel memory test system is needed for future STT-MRAM mass production that supports error bit analysis and its mode categorization on STT-MRAM chip measurement, as STTMRAM cell’s switching is a probabilistic phenomenon based on quantum mechanics. In order to meet this requireme... » read more

Challenges In Making And Testing STT-MRAM


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

Comparing New Memory Types


After decades of research and development, three new types of memory—magnetic RAM (MRAM), phase change memory (PCRAM) and resistive RAM (ReRAM)—are moving toward commercial adoption, making this an exciting time for the semiconductor and computing industries. All three of these emerging memories are enabled by new materials and will require breakthroughs in process technology and manufactur... » read more

More Memory And Processor Tradeoffs


Creating a new chip architecture is becoming an increasingly complex series of tradeoffs about memories and processing elements, but the benefits are not always obvious when those tradeoffs are being made. This used to be a fairly straightforward exercise when there was one processor, on-chip SRAM and off-chip DRAM. Fast forward to 7/5nm, where chips are being developed for AI, mobile ph... » read more

Foundries See Growth, New Issues In 2019


The silicon foundry business is poised for growth in 2019, although the industry faces several challenges across a number of market segments next year. Generally, foundry vendors saw steady growth in 2018, but many are ending the year on a sour note. Weak demand for Apple’s new iPhone XR and a downturn in the cryptocurrency market have impacted several IC suppliers and foundries, causing t... » read more

Foundries Prepare For Battle At 22nm


After introducing new 22nm processes over the last year or two, foundries are gearing up the technology for production—and preparing for a showdown. GlobalFoundries, Intel, TSMC and UMC are developing and/or expanding their efforts at 22nm amid signs this node could generate substantial business for applications like automotive, IoT and wireless. But foundry customers face some tough choic... » read more

Memory Startups To Watch


The next-generation memories are finally ramping up after years’ of delays and promises. Intel, for one, is shipping 3D XPoint, a next-generation technology based on phase-change memory. In addition, the big foundries are readying embedded MRAM. And, of course, there are a number of other players in the next-generation memory arena. There are also a number of startups that are flying un... » read more
