Abstract
A magnetic bubble memory device is provided with a plurality of memory modules each having at least one magnetic bubble chip. Each module generates a clock for determining the timing to drive the magnetic bubble chip and controls the operation of the magnetic bubble chip. The addresses of a main memory are cyclically allocated to the memory modules in a given unit, so that data transmission can be performed between the memory modules operated asynchronously with each other and the main memory allocated thereto.
