Abstract

PURPOSE: To reduce the average access time, by separating the minor loop into two or more groups and selecting them in a group unit.
CONSTITUTION: The minor loop 2 is separated into two or more groups, and the major transfer path 1 located independently of each group is fed to one set of the generator 4 and detector 3, and the transfer gate to select each minor loop 2 in a group unit belonging to each group is given between the minor loop 2 of each group and the major transfer path 1. Further, in read-out and write-in operation, one minor loop group only is made effective with four conductor patterns 14W17 independently provided with each minor loop 2', and another minor loop group is separated from the detector 3 and generator 4 as control.
