Abstract
A duplicator in a magnetic bubble memory with non-implanted patterns, a process for realizing the duplicator and a serial - parallel magnetic bubble memory having at least one of the aforementioned duplicators are disclosed. In a magnetic bubble memory having a first group of aligned non-implanted patterns and a second group of aligned non-implanted patterns, the duplicator according to the invention is characterized in that it comprises an extension conductor and a breaking conductor, the extension conductor linking the first and second groups of patterns, the breaking conductor being positioned transversely with respect to the extension conductor, the geometry of the end pattern of the first group of patterns being such that the duplication position is a stable position and the geometry of the patterns of the second group adjacent the axis of the first group being such that the reception position of the duplicated bubble is a stable position.
