Abstract

PURPOSE:To widen operation margin, by making the shape of minor loop tip at a transfer gate section as specified shape. CONSTITUTION:A tip (a) of minor loop 26-1- which transfer magnetic bubbles with a major loop 25 opposing to a hairpin part of a conductor pattern 27 of a transfer gate, has a notch of triangle shape. By this shape, the magnetic bubbles have longer staying time at the tip (a), the phase margin of transfer is widened, the current bias margin is increased and the reliability of ion injection magnetic bubble memory is increased. This is the same with flat shape of the tip (a).
