Memory Technology for Spaceborne Applications -- Crossroads for Success

Doug Sheldon, NASA JPL

Memory technology is a fundamental building block of all spaceborne application. Radiation and reliability concerns have caused the gap between commercial memories and qualified space memories to now be measured in terms of decades in some cases. Memory technologies are often one of the main bottlenecks of overall spacecraft system performance. This talk will review both volatile and nonvolatile memory technology for past, present and future JPL missions. The talk will include discussion of qualification schemes for new multi-level charge based memories as well as new resistive change based memory technologies. Also included in the talk will be examples practical memory technology limitations derived from JPL parts screening and mission operations.
