Abstract
A magnetic domain memory including bubble operated access elements for non-destructively reading the memory, for erasing bubbles from the memory and for writing new data into the memory. The access elements comprise retrograde transient bubble switches, exclusive merge elements, disjoint crossover elements and bubble generators, all of which are all-bubble logic elements.
