ABSTRACT:
A general-purpose logic cell used in a general-purpose logic cell array for a logic circuit, includes a plurality of kinds of logic circuit elements, each of which has a plurality of terminals with no connection. The plurality of kinds of logic circuit elements includes a flip-flop and a first inverter set. In this case, each of first inverters of the first inverter set is possible to be connected with an input of the flip-flop in parallel or as one of a series connection of at least two of the first inverters. Also, each first inverter is possible to be connected with an output of the flip-flop in parallel or as one of a series connection of at least two of the first inverters.
