Abstract

PURPOSE: To make it possible to read data from many minor loops in different formats individually by various gates differing in intersection position between a magnetic pattern and conductor pattern.
CONSTITUTION: Transfer gates, replicate gates or transfer-replicate gates 14 controlled by a current flowing through a common conductor pattern are provided between major loop 10 and minor loops 11, 11a and 11b. As those gates 14, various gates are used which differ in intersection position between a magnetic pattern and conductor pattern, so that data can be read from many minor loops in different formats. Therefore, all normal minor loops can be used excepting a defective pattern, so that the lowering of the yield can remarkably be improved.
