Abstract

PURPOSE:To obtain a circuit which is capable of an alteration or selection of the function, by providing the memory element the state of which can be set by the voltage applied to the power supply terminal in an integrated circuit and then securing a conversion for the state of the internal circuit according to the state of the memory element. CONSTITUTION:A connection is secured between the memory transistor TR1 having the floating gate structure and capable of an electrical writing and its load TR2, and the power supply terminal 3 is connected to the TR1 and 2 each. Then the control signal 4 supplied from the joint of the TR1 and 2 is supplied to the circuit 5 to be controlled. And in the initial stage, the threshold level of the TR1 is set lower than the voltage to be applied to the terminal 3 to turn on the TR1 as well as to set the signal 4 to 0 each. Then the electric charge is stored at the floating gate when the voltage higher than the writing voltage of the TR1 is applied to the terminal 3. And the threshold level of the TR1 is set higher than the voltage of the terminal 3. Thus the TR1 is turned off with the signal 4 set to 1 each. Then the signal 4 is converted to 0 or 1 by the voltage of the terminal 3, thus securing an alteration or selection of the function for the circuit 5.
