Abstract
An anti-fuse circuit includes an array of anti-fuses. Each anti-fuse has a tunneling magneto-resistance (TMR) element series connected with a transistor, such that breakdown of a magnetic tunnel junction (MTJ) in response to an applied first voltage stores fuse information. A sensing circuit senses and amplifies respective output signals provided by the anti-fuses.
