Abstract:
An anti-fuse memory cell includes: a first transistor connected with a word line and configured to output a second voltage based on a first voltage supplied to the word line in a write mode; a second transistor connected with a bit line, and configured to output a third voltage supplied to the bit line when the second voltage is supplied to a gate of the second transistor in the write mode; and an anti-fuse element connected to a ground line, and having an insulator film. The insulator film is set to a conductive state with the third voltage supplied from the second transistor.
