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.

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.

pMTJ STT-MRAM developer Avalanche Technology announced that NexAIoT has adopted the company's 8Mbit MRAM (P-SRAM) products in its new fanless NISE & NIFE series industrial computers.

NexAIoT says that Avalanche's P-SRAM non-volatile memory provides the performance and reliability needed for its computers. The P-SRAM helps prevent data loss during power failures.

Everspin Technologies announced that Lucid Motors has designed-in the company's 256 Kb MRAM into its master powertrain system for its Lucid Air all-electric luxury sedan.

Everspin's The MR25H256AMDF MRAM device is designed for automotive applications and is qualified to the AEC-Q100 Grade 1 standard for use in demanding memory applications that require extreme reliability in critical data capturing systems.

pMTJ STT-MRAM developer Avalanche Technology announced its third-generation 1Gb space-grade parallel asynchronous x32-interface high-reliability P-SRAM (Persistent SRAM) memory devices. The company says that these new devices enable customers to design unified memory architecture systems for high reliability aerospace applications, in extremely small form factors.

The new Parallel x32 Space Grade series is offered in 512Mb, 1Gb, 2Gb and 4Gb density options and has asynchronous SRAM compatible 45ns/45ns read/write timings. Data is always non-volatile with >10^14 write cycles endurance and 10-year retention at 125°C. All four density options are available in a small footprint 142-Ball FBGA (17mm x 11mm) package.
