Abstract
A magnetic bubble memory operative in the field-access mode is organized with separate read and write major channels accessing the same plurality of minor loops. The permalloy elements characteristic of field-access bubble memories define a novel swap function at each position at which data is moved between a stage of the write major channel and the associated minor loop. Improved data rates are achieved.
