ABSTRACT:
A universal logic module includes: a first inverter outputting an inverted input signal to an output terminal through a first transfer gate, the inverted input signal having an inverted level of an input signal provided from a first input terminal; and a second inverter outputting an inverted logic signal to the output terminal through a second transfer gate, the inverted logic signal having an inverted level of a first logic signal. The first input terminal is connected to one of a power supply line and a ground line. An input of the first transfer gate is directly connected to the other of the power supply line and the ground line. The first and the second transfer gates are complementarily turned on/off according to a level of a second logic signal. A result of a logical operation between the first and the second logic signals is outputted from the output terminal.
