Core Advantages of MRAM in Aerospace: Radiation Hardening, Unlimited Read/Write, and Low Power Consumption
With its unique properties of radiation hardening, unlimited read/write endurance, and low power consumption, MRAM is becoming the preferred choice for next-generation aerospace memory. This article will provide an in-depth analysis of MRAM's key advantages and applications in the aerospace field.
According to ESA statistics, 40% of satellite failures are caused by radiation-induced memory errors. Due to its radiation-hardening and other features, MRAM is becoming the preferred solution for next-generation aerospace memory.
Why Do Aerospace Applications Need Specialized Memory?
In the days before MRAM technology, circuit boards in aerospace equipment typically used DRAM or SRAM that had been radiation-hardened by chip manufacturers. These were combined with solutions such as multiple redundancy (storing the same data in multiple memories, and correcting data if it was corrupted by radiation), ECC (Error-Correcting Code) algorithms (using a combination of software and hardware to calculate checksums for data, which can be used to repair radiation-induced changes), and watchdog timers (using a hardware timer to periodically check the status of the memory and automatically trigger a reboot if a radiation event causes the processor to enter an error loop).
