Command-and-Control System Memory Reliability

This paper demonstrates that reliability of static and rotating magnetic memories applicable to command and control systems can be predicted with sufficient accuracy to be of some value in making system design decisions, using logical extensions of prediction methods in existing reliability handbooks. It is shown that fixed-head rotating magnetic memories are the most reliable large-scale, random-access memories now available, based on MTBF and volume of data stored. It is also noted that modular arrangements of static memory modules can be used to achieve high system memory reliability.
