Space MRAM

pMTJ STT-MRAM developer Avalanche Technology launched two new densities of its 3rd generation space-grade parallel asynchronous x32-interface high-reliability P-SRAM (Persistent SRAM) memory devices, based on its latest STT-MRAM tech, in 2Gb and 8Gb.

In June 2023 Avalanche announced that it is providing its products for satellite power applications developed by Advanced Space Power Equipment. Earlier that year Avalanche announced that its Gen-3 Space Grade Dual QSPI solution is now available in pre-production.

US-based design house and services provider Green Mountain Semiconductor (GMS) has won a Phase I Small Business Innovation Research (SBIR) contract from NASA, to develop a neuromorphic AI processor for space applications using MRAM magnetic memory.

GMS's approach involves the development of an analysis tool to optimize circuit designs for reliability and radiation resistance. This advancement will enable the use of off-the-shelf technology in space applications without the need for excessive design modifications to ensure radiation resistance.

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.

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.
