MRAM Evolves In Multiple Directions


Magnetoresistive RAM (MRAM) is one of several new non-volatile memory technologies targeting broad commercial availability, but designing MRAM into chips and systems isn't as simple as adding other types of memory. MRAM isn’t an all-things-for-all-applications technology. It needs to be tuned for its intended purpose. MRAMs targeting flash will not do as well targeting SRAMs, and vice vers... » read more

Nine Effective Features Of NVMe Verification IP For PCIe-Based SSD Storage


Non-Volatile Memory Express (NVMe) is a new software interface optimized for PCIe Solid State Drives (SSD). This paper provides an overview of the NVMe specification and examines some of its key features. We will discuss its pros and cons, compare it to other conventional technologies, and point out key areas to focus on during its verification. You will learn how NVMe Questa Verification IP... » read more

FeFETs Bring Promise And Challenges


Ferroelectric FETs (FeFETs) and memory (FeRAM) are generating high levels of interest in the research community. Based on a physical mechanism that hasn’t yet been commercially exploited, they join the other interesting new physics ideas that are in various stages of commercialization. “FeRAM is very promising, but it's like all promising memory technologies — it takes a while to get b... » read more

What Happened To Execute-in-Place?


Executing code directly from non-volatile memory, where it is stored, greatly simplifies compute architectures — especially for simple embedded devices like microcontrollers (MCUs). However, the divergence of memory and logic processes has made that nearly impossible today. The term “execute-in-place,” or ”XIP,” originated with the embedded NOR memory in MCUs that made XIP viable. ... » 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

Taming Novel NVM Non-Determinism


New memory technologies may have non-deterministic characteristics that add calibration to the test burden — and may require recalibration during their lifetime. Many of these memories are in development as a result of the search for a storage-class memory (SCM) technology that can bridge the gap between larger, slower memories like flash and faster DRAM memory. There are several approache... » read more

Non-Volatile Memory Tradeoffs Intensify


Non-volatile memory is becoming more complicated at advanced nodes, where price, speed, power and utilization are feeding into some very application-specific tradeoffs about where to place that memory. NVM can be embedded into a chip, or it can be moved off chip with various types of interconnect technology. But that decision is more complicated than it might first appear. It depends on the ... » read more

Opening Up An NVM Evaluation Kit


From toys to smartphones and even mail-order reptiles (a practice which we don’t endorse), unboxing videos are an effective and entertaining way to learn more about a product. According to a recent analysis by Shorr Packaging Corp., toys are the most watched unboxing category, followed closely by smartphones and computers. In addition to providing important product details, an unboxing v... » read more

Much Ado About 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

The Case For Antifuse OTP NVM For Secure & Reliable SoCs


Non-volatile memory (NVM) is used for persistent data and secure code storage in a wide range of electronic systems in automotive, mil-aero, power management IC (PMIC), mobile, and Internet of Things (IoT) markets. NVM comes in different flavors including multiple-time programmable (MTP), few-time programmable (FTP), and one-time programmable (OTP). When determining the ideal NVM solution, desi... » read more
