Avalanche Technology Announces Space Grade STT-MRAM For Space-IoT™ Applications

Avalanche Technology, the leader in next generation MRAM technology, new 3rd generation space-grade serial and parallel asynchronous x32-interface high-reliability P-SRAM (Persistent SRAM) memory devices, based on its latest Spin Transfer Torque Magneto-resistive RAM (STT-MRAM) technology, will go through PEMS-INST-001 flow for use in Military and Space applications.

Avalanche’s new generation (Gen-3) of High Reliability, High Density Production MRAM devices have now passed several milestones in radiation testing.

On August 2nd at Texas A&M University, assisted by CAES and Apogee Semiconductor, the Gen-3 test chip was tested for Single Event Latch-up (SEL) with none observed at Xe – 57.1MeV*cm2/mg @ 110°C to a fluence of 1E7 ions/cm2. On October 7th at Defense Microelectronics Activity, the Gen-3 test-chip was tested by Micross for Total Ionizing Dose (TID) at 175krads with negligible change in IDD. On October 27th the production 1Gb Gen-3 device was tested at Texas A&M University with No SEL observed at Xe – 56.1MeV*cm2/mg @ 100°C to a fluence of 1E7 ions/cm2.

“Avalanche’s high density MRAM devices are a key enabling technology for high-performance space computing applications. With densities up to 4 Gb and the intrinsic immunity of magnetic storage to both ionizing dose and single event effects, these devices enable applications that Flash-based memory simply cannot. Ibeos plans to incorporate this technology into our next-generation payload processor devices” said John Bevilacqua, CTO and Founder at Ibeos.

“Having simplified the system architecture in Space to enable higher reliability, lower cost systems with our Gen-3 devices, we are removing the barriers for Space Engineers to enable innovation rather than spend time validating if a terrestrial design will work in space”. said Danny Sabour, VP of Sales and Marketing at Avalanche Technology. “Having a heritage of supplying MRAM to demanding Industrial customers, the latest radiation test results from TAMU give us the confidence that we are on the cusp of a revolution in Space. We are doing our part in the democratization of Space by delivering the features that enable system designers to deliver Intelligent Autonomous AI enabled Space-IoT platforms ”.

The PEMS-INST-001 flow Parallel x32 and Serial QSPI/OSPI Space Grade series is offered in 64Mb, 256Mb, 1Gb and 4Gb density options with asynchronous SRAM compatible 45ns/45ns read/write timings or 200MHz DDR OSPI Serial interface. Data is always non-volatile with >10^16 write cycles endurance and 10-year retention at 125°C. Parallel devices will be available in a 142-Ball FBGA (17mm x 15mm) package, and serial devices will be available in a 88-ball FBGA (20mm x 15mm) package. The devices are offered in Space Grade (-40°C to 125°C) operating temperature range.
