Abstract
An antifuse programming and detecting circuit has an antifuse which is capable of being programmed to an open state or to a short state. The circuit includes a latch circuit coupled with a power supply; a programming circuit for setting the antifuse state; and a reset circuit for resetting the output signal. The latch circuit provides and latches an output signal by detecting an antifuse state. Therefore, the state of the antifuse can be programmed, identified, and latched by the circuit design in the invention. The programming and detecting operations of the circuit provides programming, current limiting, detecting, and latching functions with simplified design and reduced number of devices.
