A logic circuit performs an internal level conversion function by driving portions of the circuit with different supply voltages. In one embodiment, first and second stage storage circuits are driven with different supply voltages. In another embodiment, first and second stage storage circuits are driven with a first supply voltage and an inverter coupled to the first stage storage circuit is driven with a second supply voltage. In either case, data transfer into the storage circuits may be controlled by different states of a clock signal. The logic circuit may be a flip-flop circuit, a latch circuit, or another type of circuit.
