A fuse structure and a method for operating the same. The fuse structure
operating method includes providing a structure. The structure includes
(a) an electrically conductive layer and (b) N electrically conductive
regions hanging over without touching the electrically conductive layer.
N is a positive integer and N is greater than 1. The N electrically
conductive regions are electrically connected together. The structure
operating method further includes causing a first electrically conductive
region of the N electrically conductive regions to touch the electrically
conductive layer without causing the remaining N-1 electrically
conductive regions to touch the electrically conductive layer.
