ABSTRACT:
A bubble memory comprises a substrate with a major surface; a first storage module for storing bubbles on the left side of the surface having parallel inputs and parallel outputs; a second storage module for storing bubbles on the right side of the surface having parallel inputs and parallel outputs; a first input circuit on the left side of the surface including a serial-parallel track along which the bubbles move to the right to enter the parallel inputs of the first storage module; a second input circuit on the right side of the surface including a serial-parallel track along which the bubbles move to the left to enter the parallel inputs of the second storage module; a detector for detecting bubbles disposed equally on the left side and the right side of the surface; a first output circuit on the left side of the surface including a parallel-serial track which receives bubbles from the parallel outputs of the first storage module and moves them to the right to the detector; and a second output circuit on the right side of the surface including a parallel-serial track which receives bubbles from the parallel outputs of the second storage module and moves them to the left to the detector.
