The technology is called plated wire.  I think it is used for computer memory
in a way analogous to old fashioned ferrite core memory.  I know nothing more
about it except that it is more resistant to radiation than semiconductor
memory.  Radiation from the sun is something you have to worry about when you
put something outside the atmosphere.

Would anyone from NASA care to comment?
