Magnetic bubble memory devices |
摘要 |
In a magnetic bubble memory device, positive signal lines interconnecting a magnetic bubble memory chip located at substantially the center of an insulating substrate and lead pins at the end of the substrate are surrounded by a plurality of grounded conductors for shielding the positive signal lines so as to decrease noise induced therein by a voltage drop across coils for producing the rotating magnetic field.
