Everspin Technologies announced that it completed the development activity and entered the pilot production phase of its 28 nm 1-Gigabit (Gb) STT-MRAM chips. Everspin targets the enterprise infrastructure and data center markets which can utilize its MRAM technology to increase reliability and performance.

Everspin 1-Gb chip family (EMD4E001G) includes both 8-bit and 16-bit DDR4 compatible (ST-DDR4) interface versions of the device and are available in a JEDEC-compliant BGA package.

pMTJ STT-MRAM developer Avalanche Technology announced that it closed its latest funding round led by Thomvest Ventures, having raised $33 million.

Avalanche currently brands its MRAM chips as P-SRAM (persistent SRAM) devices. The new funds will enable the company to develop higher-density P-SRAM devices. In addition, Avalanche says it will develop the higher densities of "persistent DRAM" required for the next generation of machine learning architectures.

Researchers from the Moscow Institute of Physics and Technology developed a new MRAM architecture that is based on THz pulses which are used to change the spin state. This so-called optically-assisted MRAM is extremely efficient (the power required to switch a "bit" will be a thousand times smaller compared to current MRAM devices) and fast.

The researchers use picosecond-long pulses (3 picoseconds = one light oscillation cycle) on a specially developed structure comprised from micrometer-sized gold antennas deposited on a thulium orthoferrite sample. The researcher admit that the material is excellent for fundamental research, but it may be too early to tell whether it could be used in the future for commercial applications. The researchers tell us that they re trying to raise funds now to start fundamental studies of this new optically-assisted MRAM.

The $1 billion EU Graphene Flagship project has announced a call out for new industrial partner to provide specific industrial and technology transfer capabilities to enhance the current consortium.

One of the work packages include a €200,000 project that seeks an MRAM tools developer to leverage solutions for graphene-spintronic stacks.

Everspin announced its financial results for Q1 2019. Revenues in the quarter were to $10 million (down from $14.9 in Q1 2018). Net loss was $4.3 million (up from $1.3 million in Q1 2018).

At the end of the quarter, Everspin had $18.5 million in cash and equivalents. For the next quarter (Q2 2019), Everspin expects revenues to be in the range of $9.6 million to $10 million.

Hprobe, a developer of testing equipment for magnetic devices, announced that it has teamed up with the IMEC research institute to jointly extend Hprobe's fast testing protocols for SOT-MRAM devices.

Hprobe has already begun to optimize its test flow for SOT-MRAM devices in order to bring the characterization and testing to an industrial level with the primary objective to reduce the testing time while maximizing yield.
