Abstract

PURPOSE: To improve the reliability of readout information of a bubble memory by immediately detecting write information written in a major loop by a detector and by erasing bubbles, when the information is erroneous, without transferring it to a minor loop.
CONSTITUTION: Bubbles from generator 4 are sent to major loop 1 via two-way reproducer 11 and also divided and sent to detector 3 to hold bubble information. Bubbles circulating in major loop 1 are sent to detector 3 again via reproducer 11 and then compared to the held bubble information. When they agree, corresponding bubble information in the major loop is stored in a fixed minor loop by transfer gate 7. When they disagreee, it is erased by eraser 6 without being stored in a minor loop.
