Abstract
Electrical fuse blocks (100) of a plurality of stages are provided each of which includes a plurality of electrical fuse cores (101). The electrical fuse block (100) includes a program shift register block (103) made up of shift registers (107) which are disposed for the respective electrical fuse cores (101), sequentially transmit program enable signal FPGI, and output the program enable signal FPGI to the NMOS transistors (105) of the electrical fuse cores (101). When performing programming according to programming decision signal PBn, the program shift register block (103) transmits the program enable signal FPGI. When not performing programming, the program shift register block (103) skips the program enable signal FPGI.
