Bubble magnetic a memory units not implantes, its use for the duplication of bubbles and its application to be duplicated by a binary element and by a block of binary elements

摘要

The invention relates to a bubble magnetic memory comprising a first layer of magnetic material 4 being provided with a crystallographic axis 112 and comprising assemblies units implantes 2 are not contiguous and aligned to the propagation of bubbles 12 in a second magnetic layer 5, these patterns 2 possessing a shape such that two cavities 6 are demarcated between two adjacent motifs, characterized in that each assembly comprises a shaft 10, such as the units 2 of said assembly are disposed symmetrically with respect to this axis, these assemblies being disposed parallel to the crystallographic axis 112 of the first layer of material, and in that it comprises, associated with each set, an electrical conductor 14 enabling the duplication of the bubbles and having an axis of the different 16, arranged perpendicularly to the crystallographic axis of the first layer of material, the set of patterns corresponding being traversed by said conductor.
