Power Breaks Everything


The emphasis on lowering power in everything from wearable electronics to data centers is turning into a perfect storm for the semiconductor ecosystem. Existing methodologies need to be fixed, techniques need to be improved, and expectations need to be adjusted. And even then the problems won't go away. In the past, most issues involving power—notably current leakage, physical effects such... » read more

Here Comes 7nm


A consortium of companies involving IBM, GlobalFoundries and Samsung has rolled out the first 7nm test chip using silicon germanium as a substrate, using EUV to pattern multiple layers. While this doesn't mean the cost equation is even close to being solved, or that more than a handful of companies will push forward to that node anytime soon using SiGe as the substrate material, it does cre... » read more

Moore Memory Problems


The six-transistor static memory cell (SRAM) has been the mainstay of on-chip memory for several decades and has stood the test of time. Today, many advanced SoCs have 50% of the chip area covered with these memories and so they are critical to continued scaling. “The SRAM being used in modern systems is similar to the SRAM they were using in the 1970s and 1980s,” says Duncan Bremner, ch... » read more

Foundries Expand Planar Efforts


Competition is heating up in the leading-edge foundry business, as vendors begin to ramp up their new 16nm/14nm finFET processes. But that’s not the only action in the foundry arena. They are also expanding their efforts in the leading-edge planar market by rolling out new 28nm and 22nm processes. On one front, TSMC is offering new 28nm variants, based on bulk CMOS technology. And on an... » read more

Managing Dynamic Power


Working with finFETs is a study in contrasts. While leakage is now under control for the first time in several process generations due to the advent of different gate technology, dynamic power density caused by tightly packed transistors and higher clock speeds has become the big issue. “FinFET technology helps with reducing static/leakage power so when your logic is not active, you can sh... » read more

SoC Integration Headaches Grow


As the number of IP blocks grows, so do the headaches of integrating the various pieces and making sure they perform as planned within a prescribed power envelope. This is easier said than done, particularly at the most advanced process nodes. There are more blocks, more power domains, more states and use-model dependencies, and there is much more contention for memories. There are physical ... » read more

Analog’s Day Of Reckoning


The numbers being touted by the semiconductor industry for IoT edge devices are staggering. How they are going to be used, who will make them, or indeed who will make money from them are much less certain. The industry seems to be clear about the content of these devices. A small processor, some flash memory or possibly even some of the new memory technologies that are coming along, a radio ... » read more

Big Data Needs Bigger Memory


By Rodrigo Liang Over the last few decades, the semiconductor industry has focused its considerable technical investments in accelerating software applications. Performance metrics for new semiconductor products are often correlated with their ability to lower the latency to access data required to run specific software applications. The need for increased performance from semiconductors ... » read more
