Abstract
Provided are an electrical fuse device and a method of operating the same. The electrical fuse device may include a fuse link having a multi layer structure with at least two metal layers. The number of metal layers that are blown, from among the at least two metal layers, may vary according to either the duration of application of voltage or the strength of voltage applied.
Claims20
An electrical fuse device comprising:
- a cathode and an anode separated from each other;
- and
- a fuse link connecting the cathode and the anode,
- wherein the fuse link includes at least two stacked metal layers configured such that at least one of the stacked metal layers is blown from among the at least two stacked metal layers, the number of the stacked metal layers blown varying according to one of the strength and the duration of application of a voltage to the fuse link.
