3D NAND Race Faces Huge Tech And Cost Challenges


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

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

Using Analog For AI


If the only tool you have is a hammer, everything looks like a nail. But development of artificial intelligence (AI) applications and the compute platforms for them may be overlooking an alternative technology—analog. The semiconductor industry has a firm understanding of digital electronics and has been very successful making it scale. It is predictable, has good yield, and while every de... » read more

The Good And Bad Of 2D Materials


Despite years of warnings about reaching the limits of silicon, particularly at leading-edge process nodes where electron mobility is limited, there still is no obvious replacement. Silicon’s decades-long dominance of the integrated circuit industry is only partly due to the material’s electronic properties. Germanium, gallium arsenide, and many other semiconductors offer superior mobili... » read more

In-Memory Vs. Near-Memory Computing


New memory-centric chip technologies are emerging that promise to solve the bandwidth bottleneck issues in today’s systems. The idea behind these technologies is to bring the memory closer to the processing tasks to speed up the system. This concept isn’t new and the previous versions of the technology fell short. Moreover, it’s unclear if the new approaches will live up to their billi... » read more
