Abstract
A self-reparable semiconductor comprises first, second and spare functional units including first and second sub-functional units that cooperate to perform first and second functions. The first and second sub-functional units of the first, second and first spare functional units are functionally interchangeable, respectively. At least one of the first and second sub-functional units of the first functional unit at least one of receives and outputs an analog signal and includes an analog circuit. Switching devices communicate with the first and second sub-functional units of the first, second and first spare functional units and replace at least one of the first and second sub-functional units of at least one of the first and second functional units with at least one of the first and second sub-functional units of the first spare functional unit when the at least one of the first and second sub-functional units is non-operable.
