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.

Recent MRAM News

Samsung is progressing towards 14 nm eMRAM

In March 2019 Samsung Electronics announced that it has started to mass produce its first embedded MRAM devices, made using the company's 28nm FD-SOI process. In early 2021 Samsung announced that it managed to improve the MTJ function of its MRAM, which makes it suitable for more applications, and today, at the company's 5th Annual Samsung Foundry Forum, Samsung provides more details on its MRAM roadmap.

Samsung says it is advancing its 14 nm process which will support flash-type embedded MRAM which enables increased write speed and density. Samsung targets applications such as micro controller units (MCUs), IoT and wearables for its next-gen eMRAM.

Avalanche announces new 64Mb industrial x16-interface STT-MRAM memory devices

pMTJ STT-MRAM developer Avalanche Technology announced the immediate availability of new 64Mb Industrial parallel asynchronous x16-interface high-reliability MRAM Persistent SRAM (P-SRAM) memory devices. Avalanche's P-SRAM is based on the company's STT-MRAM technology

These new deices, the latest in Avalanche's family of Industrial data logging products, require half the board space, consume 1/4th the power and have 3 times the magnetic immunity of the equivalent density Toggle MRAM in Industrial applications.

Avalanche and LiearASICs to co-develop companion chiplets for Avalanche's Space Grade MRAM

pMTJ STT-MRAM developer Avalanche Technology announced that it has signed an agreement with LinearASICs Inc. to develop companion chiplets to offer a complete portfolio of Space Grade products with SPI and DDR interfaces, based on Avalanche's 1Gb Space Grade MRAM.

LinearASICs will provide standalone serial interface chiplets such as Octal SPI (OSPI), as well as standard memory interface chiplets such as DDR. These chiplets will be available as standalone devices or integrated modules through Avalanche.

Embedded-MRAM, what the future holds

Embedded MRAM solutions are now entering the market, as leading foundries Samsung, TSMC and GlobalFoundries are scaling-up and ramping up their solutions.

This has been a slow process, as getting next-generation technologies into large fab is never an easy task, but we are finally seeing these foundries start to offer these technologies to their customers.

Everspin reports its financial results for Q2 2021, its first profitable quarter

Everspin Technologies announced its financial results for Q2 2021. Revenues were $11.85 million, up 15% over Q1 2021 (and similar to Q2 2020), as STT-MRAM revenues jumped 56%. Net profit was $0.25 million, up from a loss of $0.46 million in Q1 2021 (and $1.29 million in Q2 2020).

At the end of Q2 2021, Everspin had $14.2 million in cash and equivalents, down from $15.5 million from the end of Q1 2021. Cash flow from operations was negative at $0.56 million. Looking into the next quarter, Everspin expects revenues to be in the range of $11.7 million to $12.8 million.

New SOT-MRAM device structure can be scaled up and is highly efficient

Researchers from Northwestern University, in collaboration with researchers from China, Italy and France, developed a new SOT-MRAM device structure that enables deterministic switching without any need for bias magnetic fields.

The new approach, unlike most earlier methods, can be scaled to large wafers with good uniformity, since it doesn't rely on having a structural asymmetry in the device. SOT-MRAM devices based on this structure could be faster and more energy-efficient than current designs.

Orthogonal Spin Transfer MRAM developer Spin Memory liquidates

Orthogonal Spin Transfer MRAM (OST-MRAM) technology developer Spin Memory is shutting down. The company's main investor and founding company, Allied Minds, said in a statement that the main reasons challenges in securing new customers and COVID-19 which "significantly delayed the required testing of its development chip with ARM".

This is a sad ending to Spin Memory, which began its way as Spin Transfer Technologies - a spin-off from NYU that was established together with Allied Minds.
