PURPOSE:To drive plural magnetic bubble memory packages having different characteristics by the same direct peripheral circuit by providing an adjusting means that applies a proper current between a bubble memory element and a direct peripheral circuit. CONSTITUTION:As adjusting means to apply a proper current between a bubble memory element 11 and a direct peripheral circuit, resistances, 16, 17, 18, 19 are connected in parallel to conductor patterns 12, 13, 14 of a generator, swap gate, replicate gate and a detector 15 to divide the current, and adjusting coils 22, 23 are connected in series to an X coil 20 and Y coil to restrict the current, and a magnetic memory package 10 is operated at an optimum current value. Thus, by shunting or restricting current given to the magnetic bubble memory element and resistance by coils, interchangeability can be given to bubble memory packages having different characteristics. |
