Abstract
The present invention relates to a one-time programmable (OTP) device including three fuses connected in parallel to a logic element which determines that the device is programmed when at least one of the fuses open. The present invention comprises a one-time programmable device that, before the one-time programmable device is programmed, provides, in response to a test signal, a simulation output signal that simulates an output signal that the one-time programmable device provides if the one-time programmable device is programmed.
