ABSTRACT:
A magnetic bubble memory device comprises a magnetic bubble memory chip, a unit for generating a bias field, a magnetic shield, and a unit for compensating the bias field, wherein the thermodependency of the bias field is compensated to approximate that of the operation characteristics of the memory chip over a wide temperature range, thereby providing a wide region in which operation is ensured.
