Abstract
PURPOSE: To avoid the increment of the resistance value for the input and output gates and then prevent an increase of the power supply voltage regardless of the increment of the memory capacity, by providing every divided information storage loop block with the input and output gates.
CONSTITUTION: A plural number of information storage loops 3, which are connected to the bubble generator 1, information writing propagation path 2 and information reading propagation path 5 incorporating the detector 4 each, are divided into several blocks A, B and so on. The input and output gates 6-1W7-1 and so on are provided for every block A and so on. With such constitution, the increment can be prevented for the resistance value of the gates 6-1W7-1 and so on. As a result, the increase of the power supply voltage becomes unnecessary regardless of the increment of the memory capacity. The number of loops 3 forming a bit for every block can be varied for every block.
