The present invention provides a method of operating a one-time programmable read only memory (OTPROM). The OTPROM includes at least a select transistor, an electrode and a dielectric layer disposed on a substrate, wherein the electrode is set up on the source region of the select transistor and the dielectric layer is set up between the electrode and the source region. The method of operating the one-time programmable read only memory includes performing a programming operation to write a digital data value of ‘1’ into the memory and performing a programming operation to write a digital data value of ‘0’ into the memory.
