Editing Magnetic-core memory (section)

====Reliability====
Core memory is [[non-volatile storage]]—it can retain its contents indefinitely without power. It is also relatively unaffected by [[electromagnetic pulse|EMP]] and radiation. These were important advantages for some applications like first-generation industrial [[programmable controllers]], military installations and vehicles like [[fighter aircraft]], as well as [[spacecraft]], and led to core being used for a number of years after availability of [[semiconductor]] MOS memory (see also [[MOSFET]]). For example, the [[Space Shuttle]] [[IBM System/4 Pi|IBM AP-101B]] flight computers used core memory, which preserved the contents of memory even through the ''[[Space Shuttle Challenger|Challenger]]''{{'}}s disintegration and subsequent plunge into the sea in 1986.<ref>{{cite web |url=http://www.magnet.fsu.edu/education/tutorials/museum/magneticcorememory.html |title=Magnetic Core Memory |publisher=National High Magnetic Field Laboratory: Museum of Electricity and Magnetism |location=US |archive-url=https://web.archive.org/web/20100610140932/http://www.magnet.fsu.edu/education/tutorials/museum/magneticcorememory.html |archive-date=10 June 2010 |url-status=dead}}</ref>
