How To Choose The Right Memory


When it comes to designing memory, there is no such thing as one size fits all. And given the long list of memory types and usage scenarios, system architects must be absolutely clear on the system requirements for their application. A first decision is whether or not to put the memory on the logic die as part of the SoC, or keep it as off-chip memory. "The tradeoff between latency and th... » read more

Mentor TLC NAND Softmodel Soft-Bit Error Injection


Designing SSD controllers targeting NAND flash as the storage media requires some heavy lifting when it comes to dealing with the soft-errors that the flash will eventually produce. This paper will look at a method to simplify the design and verification required. We model these soft-bit behaviors with the Veloce emulator in a virtual setup, which reduces the time to market for an SSD. To r... » read more

Will China Succeed In Memory?


China's fledging memory makers are expected to reach a major milestone and move into initial production this year, although vendors are already running into various roadblocks. China's domestic vendors are focusing on two markets, 3D NAND and DRAM. In both cases local vendors are either behind in technology, struggling to develop these products, or both. And one vendor recently was hit with ... » read more

Understanding Memory


New semiconductor applications are ever changing and improving our lives, from new smartphones and wearables to healthcare, factory automation, and artificial intelligence. The humble memory chip working in the background plays a critical role in enabling these technologies. For example, that awesome picture you just took would be lost forever without memory. Your computer can’t perform the i... » read more

Enabling Magnetic Tunnel Junctions Array Processing For Embedded STT MRAM


The semiconductor industry is entering a new era of next-generation memory technologies, with several major inflections taking shape. Among these is the emergence of Magnetic RAM (MRAM). Over several posts, I’ll provide background on what is driving the adoption of MRAM, highlight some of the initial challenges and discuss progress on making STT MRAM commerically viable. Today, a typical m... » read more

Get Ready For Nanotube RAM


The memory market is going in several different directions at once. On one front, the traditional memory types, such DRAM and flash, remain the workhorse technologies in systems despite undergoing some changes in the business. Then, several vendors are readying the next-generation memory types in the market. As part of an ongoing series, Semiconductor Engineering will explore where the new a... » read more

New Memories And Architectures Ahead


Memory dominates many SoCs, and it is rare to hear that a design contains too much memory. However, memories consume a significant percentage of system power, and while this may not be a critical problem for many systems, it is a bigger issue for Internet of Things ([getkc id="76" kc_name="IoT"]) edge devices where total energy consumption is very important. Memory demands are changing in al... » 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

Sorting Out Next-Gen Memory


In the data center and related environments, high-end systems are struggling to keep pace with the growing demands in data processing. There are several bottlenecks in these systems, but one segment that continues to receive an inordinate amount of attention, if not part of the blame, is the memory and storage hierarchy. [getkc id="92" kc_name="SRAM"], the first tier of this hierarchy, is... » read more

Memory Hierarchy Shakeup


It’s no secret that today’s memory chips and storage devices are struggling to keep up with the growing demands in data processing. To solve the problem, chipmakers have been working on several next-generation memory types. But most technologies have been delayed or fallen short of their promises. But after numerous delays, a new wave of next-generation, nonvolatile memories are finally ... » read more
