Abstract

PURPOSE:To increase the reliability of a magnetic bubble memory, by forming a conductor pattern that blows a ''Permalloy '' pattern and thus eliminating the bubble propagating function of a defective minor loop. CONSTITUTION:A conductor pattern 17 is formed thin at part (a) where it overlaps a ''Permalloy '' pattern 16 compared with other parts in order to secure the resistance. As a result, if a defective minor loop exists, the current is flowed to the pattern 17 overlapping the defective loop to have the blowing at the part (a). Thus the pattern 16 can also be blown by the heat caused by the blowing at the part (a). For instance, the current is flowed between terminals A and B of the pattern 17, and as a result the pattern 16 of a minor loop 11 is blown to eliminate the bubble propagating function of the loop.
