Everspin starts shipping perpendicular-MTJ based ST-MRAM chip samples

Everspin announced that it has started shipping samples based on its perpendicular magnetic tunnel junction (pMTJ) ST-MRAM. The first chip is the EMD3D256MB – a 256Mb DDR device. This is Everspin’s 3rd-gen MRAM technology.

The pMTJ ST-MRAM offers improved performance, higher endurance, lower power, and better scalability compared to previous MRAM and ST-MRAM products. The company (together with GlobalFoundries) is now focused on the production ramp of the 256Mb MRAM and is working on a scaled-down 1Gb vesrion.

A few months ago Everspin said that the company shipped more than 60 million MRAM discrete and embedded products – into data centers, cloud storage, energy, industrial, automotive, consumer, and transportation markets.

In October 2014 Everspin said they shipped a total of 40 million MRAM chips - which means that in a year and a half the company sold 20 million chips. This actually represents a deceleration, as from August 2013 to October 2014 the company shipped 30 million chips (if our estimates are correct). Everspin’s chips are higher density now, though.
