A multiple-time programming apparatus and method using one-time programming (OTP) elements are provided. The apparatus comprises a first adjusting OTP element, a second adjusting OTP element and a logic device. An adjusting data is written into the first adjusting OTP element. When a modification in an IC is desired, the value of a desired data and the prior adjusting data is performed exclusive-OR (XOR, hereinafter) together and written into the second adjusting OTP element. The logic device performs XOR on the first OTP signal outputted from the first adjusting OTP element and the second OTP signal outputted from second adjusting OTP element, and outputs the resulting OTP signal with desired value. Thus, the apparatus and the method according to an embodiment of the present invention allow modification of data using the OTP elements that prevents from using expensive multiple-time programming elements.
