ABSTRACT:
An antifuse bank (200) for an integrated circuit. The antifuse bank (200) includes a plurality of word lines (246) and digit lines (244) disposed to form an array. The antifuse bank (200) also includes a plurality of antifuse cells (230). Each antifuse cell (230) includes an antifuse (242) that is programmable to one of two fixed states. Each antifuse cell (230) also includes an access device (240) coupled to one of the word lines (246) and one of the digit lines (244) and coupled to the antifuse (242) of the antifuse cell (230). The antifuse bank (200) further includes an addressing circuit (248, 250) coupled to the array that selects an antifuse (242) of the array to be accessed. The antifuse bank (200) also includes a sensing circuit (228) coupled to the array that senses the state of the selected antifuse (242).
