Abstract
A gate of a MOS transistor connected to a fuse device in series is controlled by an AND circuit connected to the same power source as the fuse device is connected, thereby pulling down one input of the AND circuit to a ground. Thus, misprogramming of the fuse device when an LSI power source is turned ON/OFF can be prevented.
