MRAM-Info: the MRAM experts

MRAM-Info is a news hub and knowledge center born out of keen interest in MRAM memory technologies.

MRAM is a next-generation memory technology, based on electron spin rather then its charge. Often referred to as the "holy-grail of memory", MRAM is fast, high-density and non-volatile and can replace all kinds of memories used today in a single chip.

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.

Avalanche Technology raises $33 million in a new funding round

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.

Optically-assisted MRAM could outperform current MRAM devices by a factor of 1000

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.

Everspin repots its Q1 2019 financial results

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 teams up with IMEC to develop SOT-MRAM testing tools

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.

NTHU researchers manage to manipulate exchange bias by spin-orbit torque

Researchers from Taiwan's National Tsing Hua University (NTHU)managed to use a spin current to manipulate the exchange bias in Spin-Orbit Torque memory (SOT-MRAM). The researchers say that this has been a long-time challenge in the field.

To achieve this, the researchers added a platinum layer under the ferromagnetic and antiferromagnetic layers of the MRAM device. The researchers patented this technique before publishing their findings.
