It’s All About DRAM


For decades, the starting point for compute architectures was the processor. In the future, it likely will be the DRAM architecture. Dynamic random access memory always has played a big role in computing. Since IBM's Robert Dennard invented DRAM back in 1966, it has become the gold standard for off-chip memory. It's fast, cheap, reliable, and at least until about 20nm, it has scaled quite n... » read more

2.5D Becomes A Reality


Semiconductor Engineering sat down to discuss 2.5D and advanced packaging with Max Min, senior technical manager at [getentity id="22865" e_name="Samsung"]; Rob Aitken, an [getentity id="22186" comment="ARM"] fellow; John Shin, vice president at [getentity id="22903" e_name="Marvell"]; Bill Isaacson, director of ASIC marketing at [getentity id="22242" e_name="eSilicon"]; Frank Ferro, senior di... » read more

How Many Cores? (Part 2)


New chip architectures and new packaging options—including fan-outs and 2.5D—are changing basic design considerations for how many cores are needed, what they are used for, and how to solve some increasingly troublesome bottlenecks. As reported in part one, just adding more cores doesn't necessarily improve performance, and adding the wrong size or kinds of cores wastes power. That has s... » read more

Timing Is Everything


It's easy to look back on companies or products that missed the market because they were too early. Remember the Eo? The brick-like personal digital assistant that AT&T introduced in 1993 had an antenna that hinted at 4G connectivity. Unfortunately, there was no 4G available at the time, so it was just an extra wire. (Check out the video of the tablet version here.) The EO 440 Personal... » read more

New Memory Approaches And Issues


New memory types and approaches are being developed and tested as DRAM and Moore's Law both run out of steam, adding greatly to the confusion of what comes next and how that will affect chip designs. What fits where in the memory hierarchy is becoming less clear as the semiconductor industry grapples with these changes. New architectures, such as [getkc id="202" kc_name="fan-outs"] and [getk... » read more

Tech Talk: 2.5D Issues


Bill Isaacson, director of ASIC marketing at eSilicon, about how viable this packaging approach is, organic vs. inorganic interposers, where the problems are, thermal coupling, interposer cost, and what will change over the next couple years. » read more

What’s Next For DRAM?


The DRAM business has always been challenging. Over the years, DRAM suppliers have experienced a number of boom and bust cycles in a competitive landscape. But now, the industry faces a cloudy, if not an uncertain, future. On one front, for example, [getkc id="93" kc_name="DRAM"] vendors face a downturn amid a capacity glut and falling product prices in 2016. But despite the business chal... » read more

Fallout From Scaling


By Ed Sperling & Ann Steffora Mutschler Semiconductor scaling is becoming much more difficult and expensive at each new node, creating sharp divisions about what path to take next for which markets and applications. What used to be confined to one or two clear choices is now turning into a menu of items and possibilities, often with no clear guarantees for a successful outcome. Views ... » read more

Changes In Chip Design


We all know that sub-10nm is coming. But is that really what will define the next generation of semiconductors? Progress in semiconductor technology increasingly is not just about advancements in the hardware. It also involves advancements in applications and technologies peripheral to the devices themselves. That may sound counterintuitive, but going forward the technology, applications and... » read more

Memory Choices Grow


Memory is becoming one of the starting points for SoC architectures, evolving from a basic checklist item that was almost always in the shadow of improving processor performance or lowering the overall power budget. In conjunction with that shift, chipmakers must now grapple with many more front-end decisions about placement, memory type and access prioritization. There are plenty of rules ... » read more
