摘要： In a magnetic bubble memory device in which a major line and minor loops are constituted by ion-implanted tracks, a gate is constituted having two functions, i.e., having a replicate function and a pseudo swap function using conductor patterns of two layers that overlap on both the major line and on the minor loops. By controlling the pulsed current supplied to the conductor patterns of the two layers, the replicate function divides the bubble in the minor loop into two bubbles, so that one of the bubbles is taken onto the major line and is propagated to the detector. The pseudo swap function annihilates the bubble in the minor loop, divides the bubble on the major line into two bubbles and introduces one of them into the minor loop, thereby to realize the same function as that of the conventional swap gate.

摘要： A highly density magnetic bubble memory device has bubble propagation paths having different pattern periods. The distance between a propagation path having shorter period and a magnetic film for holding magnetic bubbles is made smaller than that between propagation path having longer period and the magnetic film. An insulating layer formed between the propagation path and the magnetic film through another insulating layer has a declining slope having an angle of 60.degree. or less, thereby ensuring steady propagation of the magnetic bubbles along the propagation path.
