<p><P>PROBLEM TO BE SOLVED: To provide an electric fuse memory of which area occupied by a constitution for voltage supply is small, and which performs highly precise voltage supply. <P>SOLUTION: The electric fuse memory includes a memory cell MC including a fuse element F and a first transistor TRB, an external terminal PAD, and a second transistor TRA. An N-type first transistor and the fuse element F are mutually connected in series. The external terminal PAD is a terminal which supplies external voltage VFUSE to one terminal side of the fuse element F. The second transistor TRA is an N-type transistor which supplies an internal voltage GND to the other terminal side of the fuse element F. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
