摘要
There is provided a technique for correcting a geomagnetic sensor by a correction value stored in a fuse memory. The fuse memory has a plurality of storage units and can store an arbitrary value by disconnecting or connecting the fuse provided in each storage unit. When a geomagnetic sensor (1) is manufactured, a control logic circuit (11) acquires a correction value for the temperature characteristic of the geomagnetic sensor (1) according to the measurement value of the geomagnetic sensor (1) and writes the correction value into the fuse memory (13). When the geomagnetic sensor (1) is actually used, the correction value is read from the fuse memory (13) and the measurement value of the geomagnetic sensor (1) is corrected according to the correction value.;COPYRIGHT KIPO & WIPO 2010
