| 内容記述 | This report describes the progress made toward the goal of developing a 1 Mbit bubble memory chip, based on a 6 micron period wide-gap permalloy technology. Characterization of the functions showed that the guard-rail, generator, swap, write-line, read-line and after several revisions, the replicator and the expander-detector performed acceptably in preliminary testing. Several investigations were initiated to solve the problem of low minor loop yield. A dual-spacing process, which allows the minor loop propagation elements to be more tightly coupled to the garnet film was developed. Several new propagate structures, intended to be more tolerant of small defects were also conceived. |
