Title: Fuse program circuit
Inventor: AKITA HIRONOBU
IPC: H01L27/08
Filed: 2001-05-10
Abstract: PROBLEM TO BE SOLVED: To overcome the problem such that reliable programming of fuses while an increase of the chip area is prevented is difficult. SOLUTION: One ends of fuses F1, F2-Fn are connected to a first node N1 supplied with high potential Vp. Thyristors SR1, SR2-SRn are connected between the other ends of the fuses F1, F2-Fn and a second node N2 supplied with potential Vb. A decoder 11 generates a control signal G11-G1n, G21-G2n in response to a fuse address signal FADD. One of the thyristors SR1, SR2-SRn is turned on when selected by the control signal G11-G1n, G21-G2n. After the fuses are programmed, an output end of the decoder 11 is made a high impedance state, and hence DC is prevented from flowing from the thyristors.
