pMTJ STT-MRAM developer Avalanche Technology announced that it is providing its Space Grade Persistent SRAM (P-SRAM) STT-MRAM products for satellite-based storage systems developed by RAiTEK. 

RAiTEK has designed in a 16Mb device from Avalanche's Gen 2 Space Grade family to monitor data stream status, and a 1Gb Gen 3 Space Grade to support large configuration images for the onboard FPGA used in the drives, as part of their growing portfolio of data storage and processing solutions for the space industry.

pMTJ STT-MRAM developer Avalanche Technology announced that its Gen-3 Space Grade Dual QSPI solution is now available in pre-production.

The devices are based on the company's latest generation STT-MRAM technology. Avalanche says that the new devices offer significant density, endurance, reliability, and power benefits, over existing memory solutions for aerospace and defense applications, particularly for easily configuring advanced SoCs and FPGAs, which are known to present complex design challenges.

Advanced aerospace and defense mission-critical electronics developer CAES announced that its radiation-hardened microelectronic devices are on their way to Jupiter, as part of NASA’s Lucy Mission.

Lucy’s payload is comprised of a high-resolution visible imager, an optical and near-infrared imaging spectrometer and a thermal infrared spectrometer. CAES says that the payloaduses two memory devices - 16 Mbit SRAM and 16 Mbit MRAM. The company's UT8MR2M8 chip (shown above), basedon Everspin's MRAM, is a high performance, space grade, 16Mb non-volatile MRAM device with proven flight heritage.

pMTJ STT-MRAM developer Avalanche Technology announced that it has signed an agreement with LinearASICs Inc. to develop companion chiplets to offer a complete portfolio of Space Grade products with SPI and DDR interfaces, based on Avalanche's 1Gb Space Grade MRAM.

LinearASICs will provide standalone serial interface chiplets such as Octal SPI (OSPI), as well as standard memory interface chiplets such as DDR. These chiplets will be available as standalone devices or integrated modules through Avalanche.

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.

pMTJ STT-MRAM developer Avalanche Technology announced that it is now shipping new space-grade parallel asynchronous x16-interface high-reliability P-SRAM (Persistent SRAM) memory devices, based on its latest STT-MRAM technology.

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.

High-reliability aerospace component maker Cobham (formerly Aeroflex) says that its MRAM chips were used in the payload of the ExoMars program that will soon reach Mars (in October 2016).

ExoMars is a joint-endeavor between the European Space Agency (ESA) and the Russian Federal Space Agency (Roscosmos). ExoMars 2016 is the first mission, that will consist of a Trace Gas Orbiter (TGO) and an entry, descent and landing demonstrator module (EDM) known as Schiaparelli. The main objectives of this mission are to search for evidence of methane and other trace atmospheric gases that could be signatures of active biological or geological processes on Mars.

Freescale is providing MRAM non-volatile memory technology for environmentally harsh applications, such as military, aerospace, industrial and automotive systems. Angstrom Aerospace recently announced the use of Freescale's extended temperature range 4Mbit MRAM in its magnetometer subsystem, which will be launched into space on board a Japanese research satellite.

Angstrom Aerospace is using Freescale's MRAM in its Tohoku-AAC MEMS Unit (TAMU), a magnetometer subsystem for the Japanese research satellite called SpriteSat. In developing the Satellite subsystem, Angstrom Aerospace worked closely with Dr. Johan Akerman, a renowned Swedish professor of material physics and applied spintronics at the Royal Institute of Technology.

"I've worked with MRAM for years, and when it comes to reliability and endurance for data storage, there is no comparison to Freescale's MRAM products," said Dr. Johan Akerman. "Freescale's 4Mbit MRAM device replaces both flash and battery-backed SRAM in Angstrom's module for the SpriteSat. The ability to reconfigure critical programs and route definitions during various stages of a satellite mission is a significant benefit."

TAMU plans to provide SpriteSat with magnetometer data of the Earth's magnetic field. SpriteSat is built by the Tohoku University located in Sendai, Japan, under the supervision of Professor Kazuya Yoshida. Scheduled to be launched in late 2008, SpriteSat's mission is to monitor "sprite" phenomenon (lightning effects) in Earth's upper atmosphere.

Angstrom Aerospace selected Freescale's 4Mbit MRAM device because it combines non-volatile memory with extended temperature operation, unlimited endurance and long-term data retention even when the power fails. The MRAM stores program data and FPGA configuration data on a single memory, allowing Angstrom Aerospace to reduce all storage requirements to one chip, reducing board area. At the same time, the flexibility of MRAM storage allows the system to be reconfigured significantly in space.

"Our extended temperature MRAM provides unique high temperature and high reliability capabilities for rugged system designs, such as the TAMU," said David Bondurant, MRAM product manager at Freescale. "MRAM benefits also extend to the transportation and industrial markets, where Freescale is working with developers who require growing amounts of fast but cost-effective memories that are ideally non-volatile and capable of large numbers of read and write cycles."

In addition to Angstrom Aerospace's MRAM deployment, e2v, a leading designer, developer and manufacturer of specialized components for some of the world's leading OEMs in aerospace and defense, has announced licensing of Freescale's MR2A16A product. The company has released an extended-reliability version with full-performance operations across the entire military temperature range, ideally fulfilling avionics, defense and aerospace application requirements.

Honeywell announced today that it has developed a new line of sophisticated electronic components designed specifically to meet the stringent reliability requirements for computers operating in technically advanced military and commercial aerospace conditions.

One of the products is HXNVO100 -The first non volatile Magnetic RAM (MRAM) to combine SOI CMOS technology with magnetic thin films. The HXNVO100 is a one-million bit MRAM for strategic space electronics applications and can be used as a replacement for plated wire memory, as the program memory function.
