Abstract
A magnetic bubble store, using adjoining non-implanted motifs as bubble-propagating motifs, the store comprising 3n identical, electrically interconnected storage devices, n being a positive integer, which are produced on an identical circuit chip and each comprise minor loops for storing the bubbles, at least one major loop acting as an access loop for the minor loops, first electrical component enabling bubbles to be transferred from the minor loops to the major loop and vice versa, a second electrical component enabling bubbles to be produced on the major loop, and a third electrical component enabling the bubbles on the major loop to be detected, the third, identical component, each formed by an electric conductor for bubble extension and contraction and a magneto-resistive element, being disposed in directions making an angle of 120.degree. with one another.
