Memory Power Reduction In SoC Designs Using PowerPro MG
By Various Writers - 07 May, 2014 - Comments: 0

Memories occupy over 50% of the silicon real estate on most modern SoCs and account for 50% to 70% of the power dissipation. We will show how Calypto’s PowerPro MG tool can significantly reduce the dynamic and leakage power consumption in memories by automatically inserting new memory gating logic to remove redundant reads/writes and control the sleep modes available in these memories. To ... » read more

Hiding The Electronic Crumbs
By Ed Sperling - 01 May, 2014 - Comments: 0

Imagine an old Western movie where the posse tracks the outlaws by following footsteps on a dirt trail or looking for broken branches. Now fast forward to the present, where the trail is electronic, the posse is comprised of bad guys, and the loot is frequently encrypted. As any security expert will concede, every security system can be compromised, every chip can be reverse engineered and h... » read more

The Week In Review: Design
By Ed Sperling - 25 Apr, 2014 - Comments: 0

M&A Cadence announced its intention to acquire Jasper Design Automation, adding formal technology to its roster of verification tools. The purchase price was about $146 million, the $170 million Cadence offered minus the $24 million in cash and equivalents on Jasper’s books. Tools Synopsys rolled out new LPDDR4 IP that offers up to 3.2 Gbps with low power consumption. The company is ... » read more

Executive Insight: Charlie Cheng

Semiconductor Engineering sat down with Charlie Cheng, CEO of Kilopass Technologies, to talk about his role in transforming the company. What follows are excerpts of that conversation. SE: Can you talk about your existing product and its evolution? Cheng: The founders discovered a new type of [Non Volatile (NVM), One Time Programmable (OTP)] memory and protected it with a number of patents.... » read more

Improving Yield Of 2.5D Designs
By Ann Mutschler - 18 Apr, 2014 - Comments: 0

While progress is being made on the packaging side of 2.5D design, more needs to be resolved when it comes to improving yields. Proponents of 2.5D present compelling benefits. Arif Rahman, a product architect at Altera, noted that the industry trend of silicon convergence is leading to multiple technologies being integrated into single-chip solutions. “2.5D/3D integration has multiple adva... » read more

New Rules For DRAM
By Jim Feldhan - 20 Feb, 2014 - Comments: 0

By Jim Feldhan DRAM revenues grew by more than 30% in 2013. Average selling prices increased more than 45% as capacity constraints especially for LPDRAM, motivated the transition from 2GB density parts up to 4GB DRAM units declined by almost 10%. Revenue growth rates of more than 30% combined with a declining unit base are not new to the memory market. But 2013 was a pivotal year for DRAM. ... » read more

2014 CapEx: Memory Is Leading The Way
By Adrienne Downey - 12 Dec, 2013 - Comments: 0

The semiconductor industry is expensive. Billions of dollars are spent every year to keep the fabs running, build new fabs, and push the process technology to greater and greater heights. Billions more will be spent to make 450mm production a reality. In January 2013, Semico predicted that, based on initial indications from some companies, total CapEx would be flat this year. Based on current d... » read more

Flexibility Improves Memory Interface Bandwidth
By Ann Mutschler - 10 Oct, 2013 - Comments: 0

In today’s SoCs, memory is the heart or at least one of the main elements of the design. As such, designing them carefully is paramount to achieving the best bandwidth, performance and power. Performance is very important to be able to access the memory and to trade and store information from different IPs with shared memories or local memories. From the power perspective, every access to... » read more

MRAM Begins To Attract Attention
By Mark LaPedus - 19 Sep, 2013 - Comments: 0

By Mark LaPedus In the 1980s, there were two separate innovations that changed the landscape in a pair of related fields—nonvolatile memory and storage. In one effort, Toshiba invented the flash memory, thereby leading to NAND and NOR devices. On another front, physicists discovered the giant magnetoresistance (GMR) effect, a technology that forms the basis of hard disk drives, magnetores... » read more

DRAM Remains The Status Quo
By Frank Ferro - 22 Aug, 2013 - Comments: 0

By Frank Ferro No one will argue that the “post-PC” era is here. Tablet shipments are expected to pass laptops by the end of this year, and desktops by the end of 2015. Add-in the nearly 1 billion smartphones shipment projected for 2013, and you would think that the DRAM industry would take notice of this volume. DRAM manufacturers do care about this segment of the market, but this fact... » read more
