Non destructive read out magnetic core memory apparatus having linear hysteresis loop noise cancelling core

摘要

There is provided an non destructive read out magnetic core memory apparatus in which two saturated magnetic states of a square loop hysteresis characteristic are corresponded to a binary "1" and a binary "0" to inspect a difference of permeability with respect to the magnetic core. The apparatus comprises a device for supplying a cancelling voltage of a binary 1 or a binary 0 to sense lines of the apparatus.
