Patent ID: 7373547

Claim:
A self-reparable semiconductor, comprising: a first functional unit including first and second sub-functional units that cooperate to perform a first function; a second functional unit including first and second sub-functional units that also cooperate to perform said first function; a first spare functional unit including first and second sub-functional units, wherein said first sub-functional units of said first, second and first spare functional units are functionally interchangeable, and wherein said second sub functional units of said first, second and first spare functional units are functionally interchangeable, wherein at least one of said first and second sub-functional units of each of said first functional unit, said second functional unit, and said first spare functional unit at least one of receives and outputs an analog signal and includes an analog circuit, wherein said analog signal includes at least one of a Gigabit data signal and a Gigabit control signal; and switching devices that communicate with said first and second sub-functional units of said first, second and first spare functional units and that replace at least one of said first and second sub-functional units of at least one of said first and second functional units with at least one of said first and second sub-functional units of said first spare functional unit when said at least one of said first and second sub-functional units is non-operable, wherein said switching devices selectively multiplex said analog signals based on whether said analog signals include one of said Gigabit data signal and said Gigabit control signal.
