Abstract
PURPOSE:To change more than two types of different functions in the same semiconductor device by connecting a non-volatile semiconductor memory to an external connecting terminal and selecting the function. CONSTITUTION:The connecting point C of a non-volatile semiconductor memory element 1 which can be electrically rewritten and a high resistance element 2 is defined to be the input of the functional operation selecting circuit of a function circuit part 3. For instance, at the time of completing a production process, when the non-volatile semiconductor memory 1 is turned off, the connecting point C between the memory 1 and the high resistance element 2 is an earth voltage and the functional operation selecting input of the function circuit block 3 is set to a low level. When the non-volatile semiconductor memory 1 is rewritten from the off state to an on state, the functional operating selecting input goes to a high level. In such a way, >= two types different in function can be changed in the same semiconductor device.
