ABSTRACT:
A universal logic module that may have a reduced off-leak current in universal logic cells (100) not used as logic circuits has been disclosed. A universal logic module may include universal logic cells (100) that may be formed with a second wiring for connecting universal logic cells (100) from a base configuration formed with a first wiring. Unused universal logic cell (100) may include transistors in basic cells (A to E) that are non-connected to a power supply (VDD) and/or a ground potential (VSS). Furthermore, unused universal logic cell (100) may include transistors in basic cells (A to E) that may provide a capacitor between a power supply (VDD) and a ground potential (VSS). In this way, off-leak current may be reduced and noise on a power line and/or a ground line may be reduced.
