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

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

DRAM’s Persistent Threat To Chip Security


A well-known DRAM vulnerability called "rowhammer," which allows an assailant to disrupt or take control of a system, continues to haunt the chip industry. Solutions have been tried, and new ones are being proposed, but the potential for a major attack persists. First discovered some five years ago, most of the efforts to eliminate the "rowhammer" threat have done little more than mitigate t... » read more

Week In Review: Design, Low Power


Cadence added new machine learning functionality to its Xcelium Logic Simulator to speed verification closure on randomized regressions. Xcelium ML directly interfaces to the simulation kernel and learns iteratively over an entire simulation regression, guiding the Xcelium randomization kernel on subsequent regression runs to achieve matching coverage with reduced simulation cycles. Kioxia adop... » read more

Week In Review: Manufacturing, Test


Test There is more consolidation in the ATE business. In October, Cohu completed the acquisition of Xcerra, a supplier of ATE and other products. Then, Astronics this week entered into an agreement for the sale of the intellectual-property and certain assets associated with its semiconductor test business to Advantest for $185 million in cash. The sale additionally includes a $30 million earn-... » read more

Week In Review: Design, Low Power


Tools & Standards Mentor uncorked a PCB design platform for non-specialist PCB engineers focused on multi-dimensional verification. The Xpedition platform can integrate a range of verification tools within a singular authoring environment, providing automatic model creation, concurrent simulation, cross probing from results, and error reviews to identify problems at the schematic or layout... » read more

Manufacturing Bits: Nov. 13


Quantum memories The University of Alberta has developed a new method for making quantum memories, paving the way for a next-generation quantum Internet. Quantum memory is targeted for quantum networks and computers. In classical computing, the information is stored in bits, which can be either a “0” or “1”. In quantum computing, information is stored in quantum bits, or qubits, whi... » read more
