ABSTRACT:
A magnetic bubble memory device has a plurality of memory loops which comprise minor loops and a map loop arranged independently of the minor loops. The map loop stores index data and parameter data of the memory chip. By detecting the index data, parameter data addresses are designated, and required parameter data are read out and stored in parameter memories, respectively, so as to allow operation of magnetic bubble memory chips having different storage capacities and different parameters under control of a single control circuit.
