Abstract
A base cell for an Engineering Change Order (ECO) implementation having at least a first pair of CMOS transistors and a second pair of CMOS transistors, characterized in that said at least first pair of CMOS transistors have a common gate and said at least second pair of CMOS transistors have separate gates.
Claims21
A base cell for an Engineering Change Order (ECO) implementation comprising:
- at least a first pair of CMOS transistors and a second pair of CMOS transistors, the at least first pair of CMOS transistors have a common gate and said at least second pair of CMOS transistors have separate gates.
A complex functional logic cell for an Engineering Change Order (ECO) implementation, comprising:
- a small cluster of base cells, each base cell comprising:
- at least a first pair of CMOS transistors and a second pair of CMOS transistors, the at least first pair of CMOS transistors having a common gate and said at least second pair of CMOS transistors having separate gates.
A circuit, comprising:
- a base cell comprising a first pair of complementary MOS transistors and a second pair of complementary MOS transistors, the first and second pairs of transistors formed of patterns of material layers that is asymmetrical with respect to a longitudinal middle axis of the base cell.
