Everspin announced that it started shipping 256Mb ST-MRAM samples to customers. Everspin also plans to increase the density and sample 1Gb ST-MRAM chips later this year. The new chips demonstrate interface speeds comparable to DRAM, with DDR3 and DDR4 interfaces. Volume production is expected "soon".

The new EMD3D256 chips are based on Everspin's proprietary magnetic tunnel junction (pMTJ) spin torque technology - and the company expects the new technology to enable it to produce ST-MRAM in lower geometries - and higher densities beyond 1Gb in the future.

Everspin says 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.

The new chips are the first noes produced at GlobalFoundries 300mm manufacturing MRAM line, following the agreement signed in October 2014.
