Abstract:
1. A programmable logic device comprising: a plurality of programmable logic elements whose electrical connection is controlled by first configuration data, each of the programmable logic elements comprising: a look-up table in which a relationship between a logic level of an input signal and a logic level of an output signal is determined by second configuration data, a flip-flop to which the output signal of the look-up table is input, and a multiplexer, wherein the multiplexer includes at least two switches each including a first transistor and a second transistor, wherein a gate of the second transistor is configured to be supplied with a signal including third configuration data through the first transistor, wherein one of a source and a drain of the second transistor is configured to be supplied with the output signal of the look-up table or an output signal of the flip-flop, and wherein the other of the source and the drain of the second transistor included in one of the two switches is electrically connected to the other of the source and the drain of the second transistor included in the other of the two switches.
