Claim Text:
1. A nonvolatile memory comprising: a memory area including a plurality of first magnetoresistive elements each serving as a memory element, each of the first magnetoresistive elements including a first storage layer, a first reference layer, and a first insulating film between the first storage layer and the first reference layer; and a fuse circuit including a plurality of second magnetoresistive elements each serving as an anti-fuse element and configured to store correction information of the memory area when a defect exists in the memory area, each of the second magnetoresistive elements including a second storage layer, a second reference layer, and a second insulating film between the second storage layer and the second reference layer, wherein: a resistance value of each of the plurality of first magnetoresistive elements changes between a first resistance value and a second resistance value higher than the first resistance value, each of the plurality of second magnetoresistive elements has one of the second resistance value and a third resistance value lower than the first resistance value, and the second insulating film is broken in each second magnetoresistive element having the third resistance value among the plurality of second magnetoresistive elements.
