ABSTRACT:
An apparatus and method adapted to use one-time programming (OTP) devices for multiple-time programming is disclosed. The apparatus includes a selecting device, a first adjusting OTP device, a second adjusting OTP device and a judging device. The judging device outputs a selecting signal according to whether the second adjusting OTP element is programmed. According to the selecting signal, the selecting device selects and outputs either the first OTP signal outputted from the first adjusting OTP device or the second OTP signal outputted from the second adjusting OTP device. By using this apparatus and method, the present invention serves multiple-time programming function without the high costs of manufacturing multiple-time programming devices.
