Abstract: Circuitry for programming antifuse elements is provided which permits all antifuse elements in a bank to be programmed simultaneously, thereby enhancing the speed at which antifuse elements may be programmed. In one embodiment, a feedback circuit is associated with each antifuse element to stop the flow of current through the antifuse element once it is programmed. In another embodiment, circuitry is provided for generating a separate programming pulse for each antifuse element, which is selected for programming.

Abstract: A method of verifying whether unprogrammed antifuses are leaky in a semiconductor memory. The method involves the steps of: connecting the antifuse in series with a node; providing current to the node, the current being sufficient to charge the node from a first to a second voltage; detecting whether the voltage at the node charges to the second voltage, or remains at the first voltage to indicate that the antifuse is leaky; outputting signals indicating the result of the detection; and detecting the voltage at the node remains at the first voltage indicates that the antifuse is leaky. In another embodiment, a method of verifying whether antifuses have been programmed properly in a semiconductor memory.
