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.

Embedded MRAM market, MRAM-Info poll results 2021-09

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.

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".

Researchers suggest using stochastic MRAM elements to create highly efficient AI neural network devices

Researchers from Northwestern University developed a new method of building artificial neural networks using MRAM-based stochastic computing units. The researchers say that this design could enable AI devices that are highly energy efficient.

Embedded MRAM technologies are being adopted at major foundries, which enable the use of these technologies for unconventional computing architectures that use the stochasticity of MRAM cells (rather than their nonvolatility), to perform energy-efficient computing operations. MRAM cells exhibit stochastic switching characteristics, which is a challenge for reliable memory devices. But for neural networks, this can be taken advantage of if the MTJs are appropriately designed.

Researchers developed a promising antiferromagnetic MRAM device structure

Researchers from Northwestern University and the University of Messina in Italy developed a new MRAM memory device composed of antiferromagnetic materials, which could be beneficial for use in AI systems and cryptocurrency mining.

Magnetic switching with antiferromagnet IrMn3 - device design

Antiferromagnetic materials (AFM), offer inherently faster dynamics than ferromagnetic materials (FM), have no macroscopic magnetic poles and can be scaled much better. AFM-based memory cannot be erased with external magnetic fields which could prove to be a major security advantage.
