Avalanche says that its STT-MRAM devices are smaller and more efficienct compared to Toggle MRAM based products, currently adopted in aerospace applications. The Parallel x16 Space Grade series is offered in 16Mb, 32Mb and 64Mb density options and has asynchronous SRAM compatible 45ns/45ns read/write timings. All three density options currently in production and available within industry standard lead times.

Hprobe announces a significant order for MRAM testing equipment from a tier-1 semiconductor manfacturor

Hprobe, a developer of testing equipment for magnetic devices, announced a 'significant' order for a wafer-level magnetic tester (the company's IBEX tester) from a tier-1 semiconductor manufacturer.

The equipment will be used for research and development of magnetic materials and devices, which represents a very promising technology for MRAM chips and magnetic sensors. The IBEX platform is compatible with 200mm and 300mm automated wafer probers, and is dedicated to testing MRAM magnetic tunnel junctions, bit cells based on STT-MRAM, SOT-MRAM, and Voltage Controlled (VC-MRAM) technologies.

ISI ships its first SOT-MRAM tester system

Integral Solutions International (ISI) announced its first shipment of a commercial SOT-MRAM tester system. This new equipment was developed by integrating a commercial pulser with ISI’s proprietary bias-tee and measurement electronics.

ISI says that the new tester system generates pulses as narrow as 300pS, suitable for R&D applications which require extremely narrow pulse widths. In parallel, ISI is also developing its proprietary Gen-4 Pulser System, which will provide high-throughput and cost-effective measurement solutions with the flexibility of testing either STT-MRAM or SOT-MRAM devices. The Gen-4 system is expected to be released in the fall of 2021.

Everspin reported its preliminary Q4 2020 and full-year 2020 financial results

Everspin Technologies announced its preliminary Q4 2020 financial results. Total revenues were $10 million, down from $10.1 million in Q3 and up from $9.7 million in Q4 2019. Net loss int he quarter was $1.6 million, but the company generated $0.6 million in cash flow - Everspin's second consecutive positive cash flow from operations quarter.

Looking at FY2020, Everspin's revenues increased 12.1% to $42 million. At the end of the year, Everspin had $14.6 million in cash and equivalents. In Q4 2020, the company also received its first royalty revenue from GF for embedded 22FDX process MRAM.

Samsung improves its MRAM performance, will expand its target applications

In March 2019 Samsung Electronics announced that it has started to mass produce its first embedded MRAM, made using the company's 28nm FD-SOI process. The company now announced that it managed to improve the MTJ function of its MRAM, which makes it suitable for more applications.
