Patent ID: 7262479

Claim:
A fuse bank of a semiconductor memory device comprising: a first laser fuse which includes a first laser fusing region which is stripe-shaped and disposed in a first direction, a first connecting line partially in the first laser fusing region, the first connection line is disposed to be bent in a second direction, and a second connecting line partially in the first laser fusing region, the second connecting line is disposed to be bent in a third direction; and a second laser fuse which includes a second laser fusing region which is stripe-shaped and disposed in the first direction, a third connecting line partially in the second laser fusing region, the third connection line is disposed to be bent in the second direction, and a fourth connecting line partially in the second laser fusing region, the fourth connection line is disposed to be bent in the third direction, wherein the first laser fuse and the second laser fuse are disposed adjacently in the fuse bank with a space of a predetermined distance there between, the first laser fusing region and the second laser fusing region form a laser fusing region of the fuse bank, and the first laser fuse and the second laser fuse are disposed on a plane, such that a lateral size of the fuse bank in the first direction is equal to: (number of fuses in the fuse bank minus one) multiplied by a pitch between the connecting lines, plus twice the width of the connecting lines, plus a length of the laser fusing region, and wherein the second direction is perpendicular to the first direction and opposite the third direction.
