NVM Reliability Challenges And Tradeoffs


This second of two parts looks at different memories and possible solutions. Part one can be found here. While various NVM technologies, such as PCRAM, MRAM, ReRAM and NRAM share similar high-level traits, their physical renderings are quite different. That provides each with its own set of challenges and solutions. PCRAM has had a fraught history. Initially released by Samsung, Micron, a... » read more

What Is DRAM’s Future?


Memory — and DRAM in particular — has moved into the spotlight as it finds itself in the critical path to greater system performance. This isn't the first time DRAM has been the center of attention involving performance. The problem is that not everything progresses at the same rate, creating serial bottlenecks in everything from processor performance to transistor design, and even the t... » read more

Inside The New Non-Volatile Memories


The search continues for new non-volatile memories (NVMs) to challenge the existing incumbents, but before any technology can be accepted, it must be proven reliable. “Everyone is searching for a universal memory,” says TongSwan Pang, Fujitsu senior marketing manager. "Different technologies have different reliability challenges, and not all of them may be able to operate in automotive g... » read more

Manufacturing Bits: Aug. 20


Making carbon nanotubes with AI Russia’s Skolkovo Institute of Science and Technology (Skoltech) has developed a method to monitor the growth of carbon nanotubes using an artificial intelligence (AI) technology called machine learning. Skoltech used AI to predict the performance of the synthesis of single-walled carbon nanotubes using a chemical vapor deposition (CVD) process. The tec... » read more

The Next New Memories


Several next-generation memory types are ramping up after years of R&D, but there are still more new memories in the research pipeline. Today, several next-generation memories, such as MRAM, phase-change memory (PCM) and ReRAM, are shipping to one degree or another. Some of the next new memories are extensions of these technologies. Others are based on entirely new technologies or involve ar... » read more

Carbon Nanotube DRAM


An IP design house has developed a scalable DRAM replacement using carbon nanotubes (CNTs) that abolishes the DRAM refresh rate, stores the content permanently, has better timing than DRAM and is scalable. And it lasts for somewhere between 300 and 12,000 years. “Carbon nanotube memory—it sounds so sexy that I could just shut up and not say anything,” said Bill Gervasi, principal syste... » read more

Next-Gen Memory Ramping Up


The next-generation memory market is heating up as vendors ramp a number of new technologies, but there are some challenges in bringing these products into the mainstream. For years, the industry has been working on a variety of memory technologies, including carbon nanotube RAM, FRAM, MRAM, phase-change memory and ReRAM. Some are shipping, while others are in R&D. Each memory type is di... » 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 Embedded Memories Ahead


The embedded memory market is beginning to heat up, fueled by a new wave of microcontrollers (MCUs) and related chips that will likely require new and more capable nonvolatile memory types. The industry is moving on several different fronts in the embedded memory landscape. On one front, traditional solutions are advancing. On another front, several vendors are positioning the next-generatio... » read more
