Abstract
In fuse program circuits, fuse element FS is implemented using metal interconnect at third or higher layer of multilayer metal interconnect. In each fuse program circuit, program information and fuse select information are sequentially transferred using a scan flip-flops, and fuses are selectively and electrically blown one by one. The fuse program circuit provided with fuse elements that can be programmed even after packaging is implemented with low power consumption and a low occupation area.
