摘要:
A fuse circuit includes a fuse having an intact state and a blown state. The fuse can be switched to the blown state by enabling a blowing current to flow through the fuse. The fuse is coupled between a first transistor and a second transistor in series. The first transistor and the second transistor are complementary transistors and operable for reducing an electrostatic discharge current flowing through the fuse. The first transistor and the second transistor are turned on to enable the blowing current to flow through the fuse.
