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.
Avalanche's 2nd-Gen P-SRAM evaluation kit
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.
The new devices will be available to customer that participate in Avalanche's early access program, and customers can request early samples.
Avalanche started shipping its Serial P-SRAM STT-MRAM memory devices in September 2020. In May 2021 the company announced it started shipping space-grade 16Mb - 64Mb devices. In 2019 Avalanche Technology announced a $33 million funding round led by Thomvest Ventures.
