Why This Roadmap Matters


The semiconductor industry is now officially looking beyond PCs and servers, establishing metrics and guidance for existing and developing market segments rather than just focusing on how to get to the next process nodes. The IEEE's International Roadmap for Devices and Systems marks a fundamental shift in the industry. The uncertainty that has ensued ever since the introduction of 3D transi... » 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

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

An Insider’s Guide To Planar And 3D DRAM


Semiconductor Engineering sat down to talk about planar DRAMs, 3D DRAMs, scaling and systems design with Charles Slayman, technical leader of engineering at network equipment giant Cisco Systems. What follows are excerpts of that conversation. SE: What types of DRAM do network equipment OEMs look at or buy these days? Slayman: When we look at DRAM, we look at it for networking applicatio... » 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

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

Hybrid Memory Cube – Ready For Prime Time


With the release this week of Hybrid Memory Cube (HMC) 2.0, designers can get their hands on mature, standards-based IP that can be used to significantly scale the performance of servers and data centers. HMC offers bandwidths up to 320 GB/s – 12X that of standard memory solutions like DDR4 – while consuming significantly less power. These benefits are too significant to ignore for ASIC, So... » read more

Memory Directions Uncertain


Semiconductor Engineering sat down with a panel of experts to find out what is happening in world of memories. Taking part in the discussion are [getperson id="11073" comment="Charlie Cheng"], chief executive officer at [getentity id="22135" e_name="Kilopass Technology"]; Navraj Nandra, senior director of marketing for Analog/Mixed signal IP, embedded memories and logic libraries at [getentity ... » read more

Will There Be A DDR5?


DDR4 rollouts have begun. And in the DRAM world that begs the question, 'What comes next?' The answer isn't so obvious. While there have been suggestions inside of JEDEC — the Joint Electron Device Engineering Council, which has overseen the standards for double-data-rate synchronous DRAM — to develop a DDR5 standard, it's not the only solution being considered. And in the minds of some... » read more

Driving Memory Beyond DDR4


While attending recent technology trade shows, the Intel Developer’s Forum (IDF) in August and last week’s ARM TechCon, I participated in many interesting discussions around server performance, power consumption, memory bandwidth and capacity. The race to introduce higher-performing servers that consume less power is fueled by the growing demand for new applications in the enterprise, commu... » read more
