<p>A trimming code setting circuit formed between a first and a second potential source (VDD,GND) includes a transistor (M1;M2;M3), an inverter (IN1;IN2;IN3), a capacitor (C1;C2;C3) and a fusible resistor (R1;R2;R3). The transistor has its source-drain passage connected between the first potential source and an output node (1). The inverter is connected between the output node and a gate of the transistor. The capacitor is connected between the first potential source and the output node. The resistor is connected between the output node and the second potential source. A steady-state current does not flow after the resistor is cut and this allows an increase in current capability of the circuit. There is no possibility for the trimming codes to change with lapse of time. <IMAGE></p> |
