  • CIRCUIT FOR PROGRAMMING ANTIFUSE BITS
    Publication number: 20040223397
    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.
    Type: Application
