Space Grade Gen 3

Discrete MRAM

Avalanche’s Persistent SRAM (P-SRAM™) is non-volatile memory utilizing advanced STT-MRAM with simplified SRAM compatible read/write timings and no need for wait states or wear leveling as the data is immediately available when written. Architected for high reliability and radiation resilience, the products on this page and the pin-compatible extended qualification and screening options are ideal for high reliability applications such as aerospace and defense.

"For secure, Hi-Rel and Space applications, Avalanche’s MRAM technology has emerged, filling a long-term void in the supply base for essential non-volatile memory technology. Avalanche is providing industry standard interface compatibility, radiation tolerance, reliability, exceptional retention/endurance properties, low power, and industry leading bit-density on an affordable trusted platform. We have been waiting for the benefits of MRAM technology for decades and now we have it – this is a critical and enabling technology."
Tim Canales, Senior Fellow
BLUEHALO - Advanced Innovation
"With Avalanche we can maintain excellent upset rates while substantially increasing our boot memory density, saving on board space and providing a board level solution that’s configurable for a variety of mission requirements and price points."
Robert Hillman, Director of Engineering
Power Device Corporation
