Geoff Tate Flexlogix

This is the second in series of interviews we will do with executives inside the fabless semiconductor ecosystem. Geoff Tate was the founding CEO of Rambus and is now CEO and co-founder ofFlex Logix (embedded FPGA). This one should be of great interest due to the recent $16.7B acquisition of Altera by Intel. We all now know the importance… Read More


Statistical Simulation Provides Insight into 6T SRAM Optimization

Statistical Simulation Provides Insight into 6T SRAM Optimization
by Tom Simon on 08-24-2016 at 12:00 pm

ARM’s Azeez Bhavnagarwala recently gave a talk hosted by Solido on the benefits of variation aware design in optimizing 6T bit cells. Azeez sees higher clock rates, increasing usage of SRAM per processor and the escalating number of processors, shown in the diagram below, as trends that push designers toward 6T. Six Transistor… Read More

1-T SRAMs in high-density, portable applications
by Farzad Zarrinfar on 08-02-2016 at 7:00 am

For SoCs designed for various applications such as mobile, automotive, wearable computing, gaming, virtual reality, PC, imaging, security, and IOT applications, it is incredibly important to keep area (cost) and power as low as possible. Considering the growing percentage of chip area used for memory, it makes sense to choose… Read More


A Brief History of Platform Design Automation

A Brief History of Platform Design Automation
by Daniel Payne on 07-01-2016 at 12:00 pm

Two weeks ago I spoke on the phone with Albert Li, Founder and CEO of Platform DA about his EDA company. Prior to founding Platform DA in Beijing, Li worked at Accelicon which was acquired by Agilent in December 2011. Mr. Li graduated from Tsinghua University and Vanderbilt University, both in Electrical Engineering, and has written… Read More


SRAM Optimization for 14nm and 28nm FDSOI

SRAM Optimization for 14nm and 28nm FDSOI
by Daniel Payne on 05-16-2016 at 4:00 pm

I’ve done SRAM and DRAM design before as a circuit designer from 1978-1986, but in 2016 there are so many more challenges to using 28nm and 14nm on FDSOI technology. One way to keep abreast of SRAM design is to read conference papers, so I just finished a paper from authors at STMicroelectronics and MunEDA presented at the IEEE… Read More


10nm SRAM Projections – Who will lead

10nm SRAM Projections – Who will lead
by Scotten Jones on 03-25-2016 at 12:00 pm

At ISSCC this year Samsung published a paper entitled “A 10nm FinFET 128Mb SRAM with Assist Adjustment System for Power, Performance, and Area Optimization. In the paper Samsung disclosed a high density 6T SRAM cell size of 0.040µm[SUP]2[/SUP]. I thought it would be interesting to take a look at how this cell size stacks … Read More


SEMATECH, Silvaco and SRAM

SEMATECH, Silvaco and SRAM
by Paul McLellan on 09-04-2015 at 7:00 am

SEMATECH has been around for over 20 years, starting in Austin. Today it is in upstate New York which increasingly seems to be the area for semiconductor research with IBM (still doing research although they sold their semiconductor business to GlobalFoundries), GlobalFoundries’ own Fab 8, the College of Nanoscale Science… Read More


Optimizing SRAM IP for Yield and Reliability

Optimizing SRAM IP for Yield and Reliability
by Daniel Payne on 08-31-2015 at 12:00 pm

My IC design career started out with DRAM at Intel, and included SRAM embedded in GPUs, so I recall some common questions that face memory IP designers even today, like:

  • Does reading a bit flip the stored data?
  • Can I write both 0 and 1 into every cell?
  • Will read access times be met?
  • While lowering the supply voltage does the cell data retain?

Jen-Tai Hsu Joins Kilopass and Looks to the Future of Memories

Jen-Tai Hsu Joins Kilopass and Looks to the Future of Memories
by Paul McLellan on 08-18-2015 at 7:00 am

Kilopass has a new VP of engineering, Jen-Tai Hsu. I sat down with him last week to find out where he came from and where he and Kilopass are going.

He grew up in Taiwan and went to National Taiwan University where he studied electrical engineering. Then he came to the US and went to Case Western Reserve University to get a masters degree,… Read More
