ABSTRACT:
A configuration for a laser fuse bank is disclosed wherein the available space is more efficiently used. Fuses of graduated width and variable configuration are placed so as to minimize the average distance between fuses and maximize fuse density. Alternatively, a common source is added to a standard laser fuse structure such that it intersects the fuses and the number of available fuses is doubled.
