Low power computer memory system

Abstract

One of the critical technologies for aerospace missions is electrical power. Increased emphasis is being given to reducing power requirements of electronics as well as toward improvements in power sources themselves. In present day aerospace computers the memory subsystems consume approximately 40 to 60% of the total computer power. This is primarily due to the high drive requirements of present core memories or to the sensing problems associated with thin film memories. Reduction in memory power requirements would, therefore, have a significant effect on extending allowable mission time.
