Part I: Memory Design for Spaceborne Computers

April 28, 2005
Bldg. 11, AETD Conference Room

Abstract

This seminar will discuss the design of memory systems for spaceborne computers. While normally associated with computers, many of the concepts in this seminar also apply to the "configuration memory" of FPGAs. The seminar will include a discussion of the following topics:

• Memory classification
• Review and discussion of spaceborne memory system architectures in both manned and robotic NASA missions
• Robust memory system design and criteria
• Impact of software on memory system integrity
• Frequently seen problems and lessons learned
• Component considerations - Cell and device failures - Lock up
• Recommendations
