Modular AI chip Engineers at the Massachusetts Institute of Technology (MIT), Harvard University, Stanford University, Lawrence Berkeley National Laboratory, Korea Institute of Science and Technology, and Tsinghua University created a modular approach to building stackable, reconfigurable AI chips. The design comprises alternating layers of sensing and processing elements, along with LEDs t... » read more

What’s In A Name(space)? Optimizing SSD Controller Performance And Verification
By Himani Kaushik - 12 May, 2022 - Comments: 0

Solid state drives (SSDs) have come to the forefront as a promising solution for today and tomorrow’s immense data transfer and storage demands. And SSDs themselves are constantly evolving with upgrades of their critical components to provide higher access speeds. One such component for the NVMe specification is created by the division of non-volatile memory (NVM) into what are commonly known... » read more

A Framework For Ultra Low-Power Hardware Accelerators Using NNs For Embedded Time Series Classification
By Fraunhofer EAS - 09 Mar, 2022 - Comments: 0

In embedded applications that use neural networks (NNs) for classification tasks, it is important to not only minimize the power consumption of the NN calculation, but of the whole system. Optimization approaches for individual parts exist, such as quantization of the NN or analog calculation of arithmetic operations. However, there is no holistic approach for a complete embedded system design ... » read more

SOT-MRAM To Challenge SRAM
By Bryon Moyer - 13 Jan, 2022 - Comments: 1

In an era of new non-volatile memory (NVM) technologies, yet another variation is poised to join the competition — a new version of MRAM called spin-orbit torque, or SOT-MRAM. What makes this one particularly interesting is the possibility that someday it could supplant SRAM arrays in systems-on-chip (SoCs) and other integrated circuits. The key advantages of SOT-MRAM technology are the pr... » read more

MRAM Evolves In Multiple Directions
By Bryon Moyer - 11 Mar, 2021 - Comments: 1

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
By Bryon Moyer - 17 Feb, 2021 - Comments: 3

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?
By Bryon Moyer - 25 Aug, 2020 - Comments: 0

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
By Bryon Moyer - 07 Apr, 2020 - Comments: 0

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
