Kioxia Corporation (Toshiba's memory unit that was spun-off in 2021), in collaboration with SK Hynix, announced that it has developed the world's smallest 1Selector-1MTJ cell.

Kioxia says that the two companies have demonstrated a reliable 1 selector-1 MTJ (1S1M) cell read/write operation with low read disturb rate of <1E^-6 in 64 Gb cross-point array architecture. They have implemented cross-point 1S1M chips integrated in Half Pitch (HP) of 20.5 nm and MTJ CD of 20 nm using As-doped SiO2 selector and perpendicularly magnetized MTJ (p-MTJ).

Researchers from  Purdue University were awarded with a new project to advanced AI using research performed at Purdue for over a decade. The CHEETA:CMOS+MRAM project will utilize a CMOS+X approach specifically leveraging the unique capabilities of MRAM memory to design efficient in-memory computing hardware fabrics.

The CHEETA project aims to deliver impactful improvements in energy efficiency and sensor-to-decision latency compared to the current commercial standard. The project received funding from the Applied Research Institute. 

Researchers from the Institute of Science Tokyo (formerly Tokyo Tech), in collaboration with Western Digital, has developed a new high-performance material suitable for low-power SOT-MRAM.

The researchers are using BiSb material under the CoFeB/MgO, with perpendicular magnetic anisotropy. By optimizing the interfacial layer thickness as well as deposition condition of BiSb, the researchers managed to achieve a large effective spin Hall angle and relatively high electrical conductivity. The researchers continued to demonstrate spin–orbit torque-induced magnetization switching driven by a small threshold current density.

Everspin Technologies announced that Lucid Motors has chosen the company's PERSYST MRAM technology to be used in its latest all-electric Gravity SUV. 

Lucid's Gravity uses Everspin's MR25H256A, a 256Kb serial MRAM. Everspin says it was selected because it meets the AEC Q100 Grade 1 specification of -40C to 125C temperature operation. The MRAM is used in the Gravity to handle data logging and parameter storage to assist in the efficient operation of the all-electric powertrain.
