Power/Performance Bits: April 11


High-efficiency silicon photodetector Electrical engineers at the University of California, Davis, and W&WSens Devices, Inc. built a new type of high-efficiency photodetector that could be monolithically integrated with silicon electronics. The new detector uses tapered holes in a silicon wafer to divert photons sideways, preserving the speed of thin-layer silicon and the efficiency o... » read more

Power/Performance Bits: Feb. 7


Infrared links for data centers Researchers at Penn State, Stony Brook University and Carnegie Mellon University developed a free space optical link for communication in data centers using infrared lasers and receivers mounted on top of data center racks. According to Mohsen Kavehrad, professor of electrical engineering at Penn State, "It uses a very inexpensive lens, we get a very narrow... » read more

Why Wait To Double Your Network Bandwidth?


10 Gigabit Ethernet (10GbE) has been the economical workhorse high-performance interconnect for data center server networks for years. 40GbE and 100GbE of course are just derivatives of 10GbE, with 4 x 10GbE channels or 10 x 10GbE channels. 10GbE, therefore, has been the building block for server racks everywhere. But with the massive explosion of data from the Cloud, Internet of Things (IoT) a... » read more

Faster SerDes For More Efficient Data Centers


The evolving data center presents an imposing set of challenges for system architects as Dennard Scaling fades and Moore’s Law wanes. These include an exponential increase in data, shifting architectural bottlenecks and a never-ending demand for higher performance within the same power and thermal envelopes. The Internet of Things (IoT), Big Data analytics, in-memory computing and machine ... » read more

Executive Insight: Charlie Cheng


[getperson id="11073" comment="Charlie Cheng"], CEO of [getentity id="22135" e_name="Kilopass Technology"], sat down with Semiconductor Engineering to talk about the limitations of DRAM, how to get around them, and who's likely to do that. What follows are excerpts of that discussion. SE: What are the top market segments from a [getkc id="22" kc_name="memory"] standpoint? Cheng: The top o... » read more

From The Data Center To The Mobile Edge


At the heart of the Internet of Things is the complex interplay between the needs for both low power and high performance (LPHP), a perplexing challenge rooted in the de-facto bifurcation of the IoT itself. For example, lower power mobile devices, systems and lite endpoints make up the vast majority of forward-facing consumer infrastructure, while high-performance servers at the back end are ta... » read more

Power/Performance Bits: Oct. 11


Getting to 1nm Researchers at the Lawrence Berkeley National Laboratory, UC Berkeley, University of Texas at Dallas, and Stanford University created a transistor with a working 1nm gate from carbon nanotubes and molybdenum disulfide (MoS2). "The semiconductor industry has long assumed that any gate below 5 nanometers wouldn't work, so anything below that was not even considered," said fir... » read more

Power/Performance Bits: Aug. 30


Scalable data center chip Princeton University researchers designed a new scalable chip specifically for data centers and massive computing systems. The team believes the chip, called Piton, can substantially increase processing speed while slashing energy needs. The chip architecture is scalable; designs can be built that go from a dozen cores to several thousand. Also, the architecture ... » read more

Architecting Memory For Next-Gen Data Centers


The industry’s insatiable appetite for increased bandwidth and ever-higher transfer rates is driven by a burgeoning Internet of Things (IoT), which has ushered in a new era of pervasive connectivity and generated a tsunami of data. In this context, datacenters are currently evaluating a wide range of new memory initiatives. All seek to optimize efficiency by reducing data transport, thus sign... » read more
