Abstract
A fuse latch of a semiconductor device is disclosed. The fuse latch includes a plurality of PMOS transistors and a plurality of NMOS transistors to latch fuse cell data. In the fuse latch, the PMOS transistors are formed in a single P-type active region, and the NMOS transistors are arranged in a two-stage structure at one side of the P-type active region.
