Everspin starts to produce commercial 40nm 256Mb STT-MRAM chips

Everspin announced that the company recorded revenue for its first 40nm 256Mb STT-MRAM (pMTJ) products in Q4 2017, and is now ramping up volume production. The 256Mb STT-MRAM employs an innovative ST-DDR3 interface, unlocking performance previously unattainable in legacy MRAM components.

These new 40nm 256Mb chips are produced by Global Foundries, Everspin's production partner, which says it is on track to its risk production release of 22FDX eMRAM in 2018.

Crocus Nano Electronics successfully tests its 90 nm pMTJ STT-MRAM tech

Crocus Nano Electronics (CNE) announced successful test results for its 90 nm pMTJ STT-MRAM technology. The company says it has developed unique materials that are able to deliver high data retention, tolerance to external magnetic fields and low switching currents. The company expects to produce its first engineering samples in later in 2018.

CNE also reports that it complete the design of its STT-MRAM test chip for further technology improvement in cooperation with eVaderis. Together with eVaderis, CNE created a "universal memory chip" able to serve as a platform for technology development through a wide range of MTJ sizes, currents and voltages ranges.

eVaderis demonstrates an innovative MRAM-based, memory-centric MCU

eVaderis logoeVaderis announced that it has successfully demonstrated a fully functioning design platform through an ultra-low-power microcontroller (MCU) in Beyond Semiconductor’s BA2X product line. eVaderis says that this new MCU is ideally suited for battery-powered applications in IoT and wearable electronics.

The new design uses imec's perpendicular, STT-MRAM technology that enables the new MCU to achieve non-volatile operation with high-speed read/write and low voltage. The MCU includes 3 Mb of on-chip STT-MRAM memory.
