    摘要: 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.

    摘要: 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.

    摘要: The master slice type semiconductor integrated circuit includes sequential circuit cells (2) and combinational circuit cells (3), which are alternately arranged in an inner core area on a semiconductor chip (1), and a plurality of selective driving elements (MC101 to MC108, MC201 to MC216 and MC301 to MC316), which are connected in a shape of a tree, for selectively distributing a poliphase clock signal for each division area formed by uniformly dividing the inner core area. The plurality of selective driving elements are placed and connected on the semiconductor chip such that load and wiring length between the sequential circuit cells within the respective division areas and input terminals to which the poliphase clock signal is inputted are equal. Due to this configuration, it is possible to cope with a poliphase clock, and also possible to reduce a clock skew between circuits, and further possible to provide a master slice type semiconductor integrated circuit in which an electric power consumption can be reduced.
