Abstract

PURPOSE: To secure the sufficient region for the transfer control circuit without lowering the reading velocity by forming the plural number of the information storage part with the loop-type transfer line having the flection part and then providing the information propagation path of the fixed transfer pattern cycle close to the information storage part.
CONSTITUTION: Information storage parts 3"... form the U-shaped loop-type transfer line containing the flection part inside at part, and consist of the capacity of 2N1/2 bits, where N shows the capacity of the entire chip. In such constitution, the region can be secured sufficiently for the transfer control circuit to increase the action margin. The transfer pattern cycle of information propagation line 4' close to parts 3"... features the double of that at parts 3"..., and no lowering of the reading velocity is caused for the information compared with the case of the 4-equal divisions. As a result, a magnetic bubble memory device can be obtained with the sufficient region secured for the transfer control circuit without lowering the reading velocity of the information.
