ABSTRACT:
A programming circuit used with a semiconductor memory comprising normal as well as spare memory cells allows any of the normal memory cells to be replaced by a spare memory cell and includes a fuse and a MOSFET connected in series between first and second power supply terminals. A voltage signal at the junction between the fuse and the MOSFET is delivered to the gate of the MOSFET after being delayed after power is supplied.
