Abstract
PURPOSE: To shorten the access time and cycle time by providing not less than two kinds of block replicators that differ in timing when a gate driving pulse current starts flowing to a gate part taking magnetic bubbles, stored in a minor loop via a writing line, out to a readout line.
CONSTITUTION: The magnetic bubble memory element consists of magnetic bubble generator 11, writing line 12, swap gate 13, conductor 14, driving circuit 15 for the swap gate, minor loops 26 and 27, block replicators 28 and 29 differing in pulse current phase, conductor 20, driving circuit 21 for the block replicators, readout lines 30 and 31, and detector 24. As driving circuit 21 starts flowing electric current to conductor 20, replicator 28 splits and replicates bubbles between 75 and 110°, for example, synchronizing with revolving magnetic field 25 and leaves one bubble in minor loop 26 while moving the other to readout line 30. Replicator 29 provides the same operation between 160 and 200°. The access time and recycle time can, therefore, be shortened.
