Space Grade Ava-MRAM™

Boot Memory

Discrete Ava-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.

The foundation of Trusted Boot

Boot memory holds the golden image, boot code, bitstreams, cryptographic keys, and configuration data that a platform needs to start in its intended state. Those assets make memory part of the system’s root-of-trust architecture.
