Abstract
A feasibility study of a magnetic bubble memory module for space applications is reported. All technological aspects were considered: manufacturing of a garnet allowing the memory to operate between -25 and +60 C and capable of carrying bubbles with diameters between 6 and 2.5 microns; realization of memory chips of 1 kbits and 4 kbits; demonstration of the module's operation at a frequency of 100 kHz of the rotating field; stop-start operation and nonvolatility of the information; and a proposal for a new packaging consisting of a case with 4 chips and having a capacity between 256 kbits (4 chips of 64 k) and 1 Mbits (4 chips of 256 k).
