A Comparison of Space-Grade Memory Technologies

A Comparison of Space-Grade Memory Technologies

Satellite and spacecraft sub-systems are increasingly using more and more on-board storage, and the choice of memory has a major impact on overall capacity, physical size, power-consumption, speed, reliability and mission lifetime. One technology is fabricated with known erroneous bits, with limits on the total number of permitted write operations, which could constrain or jeopardise your mission’s on-board storage needs! SDRAM, MRAM, NAND flash, NOR Flash, SONOS, SRAM, PROM, DRAM, EEPROM, volatile, non-volatile and SPI memory, which one is right for you?

Fast, High-Capacity, Endurant MRAM for Space Applications

MRAM offers the space industry the speed of SRAM, a density approaching DRAM, the non-volatility of flash memory, unlimited read/write endurance and low power consumption. These on-board storage benefits will enable new use cases for satellite applications.

DFM & DFA : Building Your Space-Grade PCB Right-First-Time

Your customer wants tested hardware next month and you have budget for a single PCB spin: before sending your ODB++ or Gerber artwork, there are important Design-for-Manufacturing (DFM) checks to ensure your layout complies with formal standards, the fabricator can make it and your new bare-board is returned right-first-time. There are also Design-for-Assembly (DFA) checks to verify your sub-contractor can reliably place parts onto the PCB - I will not sign-off a new build until DFM and DFA have passed!
