MRAM Magnetic Immunity

The main threat for the wide adoption of MRAM memories continues to be their lack of immunity to magnetic fields. MRAM magnetic immunity (MI) levels has seen significant research over the years and new data is continuously published from the main MRAM vendors.

This data, however, is rarely compared to magnetic field exposure scenarios… Read More

Intel Optane Micron SemiWiki

– Micron shuts down once promising XPoint
– Lehi Utah fab to be sold off- Had been a $400M drain
– Unique memory couldn’t follow flash down cost/yield curve
– Savings helps Micron but its now just another memory maker

XPoint “Coulda been a contender”

XPoint should have amounted to more… Read More

profile simulations

Spin-transfer torque magnetoresistive RAM (STT-MRAM) has emerged from several foundries as a very attractive IP option.  An introduction to MRAM technology from GLOBALFOUNDRIES was provided in this earlier SemiWiki article. [1]

Briefly, STT-MRAM is a non-volatile storage option with the following attractive characteristics… Read More

eFLASH Replacement MRAM

Embedded non-volatile memory (eNVM) plays an essential role in most systems and SoCs. eFLASH has found its way into a wide range of devices, including automotive, industrial, IoT and those in a mixture of other markets. NAND Flash has proven to be a workhorse in all of these areas. For instance, MCUs use them for code and data storage… Read More

Trimming for eMRAM in Tessent

It’s amazing to think that Apollo moon mission used computers that were based on magnetic core memories. Of course, CMOS memories superseded them rapidly. However, over the decades since, memory technologies have advanced significantly, in terms of density, power and new types of technologies, e.g NAND Flash. Ever since the… Read More


A Quick TSMC 2019 Tech Symposium Overview

A Quick TSMC 2019 Tech Symposium Overview
by Daniel Nenni on 04-26-2019 at 7:00 am

This year TSMC did a FinFET victory lap with the success of 16nm, 12nm, 10nm, and 7nm. It really is well deserved. Even though TSMC credits the ecosystem and customers, I credit TSMC and their relationship with Apple since it has pushed us all much harder than ever before. TSMC CEO C.C. Wei summed it up nicely in his keynote: Innovation,… Read More

by Daniel Nenni on 12-10-2018 at 7:00 am

Hello, my name is Daniel Nenni and I am a semiconductor conference addict. I just can’t seem to get enough. The semiconductor ecosystem is very wide now and moves so quickly it is nearly impossible to keep up without constant conference attendance. As a SemiWiki contributor not only do I get free conference passes, I get access to … Read More
