Abstract
A programmable circuit in an integrated circuit provides a programmed signal, which is based on the state of a first node. An anti-fuse includes a first terminal coupled to the first node and a second terminal coupled to a programming bus. An anti-fuse programming pad is coupled to the first programming bus for permitting a sufficient voltage to short the first anti-fuse to be applied to the first programming bus from external to the integrated circuit. The state of the programmed signal can be used to replace a primary circuit element in the integrated circuit, such a row or column of memory cells in a memory integrated circuit, with a redundant circuit element.
