CIRCUIT WITH MAKE-LINK FUSE AND SEMICONDUCTOR DEVICE UTILIZING THE SAME

摘要

PROBLEM TO BE SOLVED: To ensure the operation reliability of a circuit by cutting off a current flowing through a make-link fuse. SOLUTION: The circuit with make-link fuses is composed of a transistor P3 having a drain and a source, a first make-link fuse F3 connected between the gate of the transistor P3 and a first voltage node and a second make-link fuse F4 connected between the gate of the transistor P3 and a second voltage node. This cuts off the current flowing through the make-link fuses F3, F4 and ensures the operation reliability. This circuit is also available, when make- link fuses exist in the form of a box in a semiconductor device redundancy circuit. COPYRIGHT: (C)2003,JPO
