Abstract:
1. A self-reparable semiconductor, comprising: M functional units each including N sub-functional units, wherein each of said M functional units perform the same function, wherein M and N are greater than 1, and wherein corresponding ones of the N sub-functional units in each of said M functional units perform the same function and wherein each of the N sub-functional units in one of said M functional units performs a different function; a first spare functional unit including X sub-functional units, wherein X is greater than or equal to one and less than or equal to N and wherein said X sub-functional units of said first spare functional unit are functionally interchangeable with corresponding sub-functional units of said M functional units and wherein said X sub-functional units are provided for said at least two of the N sub-functional units; second spare functional unit including X sub-functional units that are functionally interchangeable with corresponding sub-functional units of said M functional units; and a plurality of switching devices configured to replace at least one of said N sub-functional units with at least one of said X sub-functional units when said at least one of said N sub-functional units is non-operable, wherein said switching devices are further configured to replace a plurality of corresponding non-operable sub-functional units that perform the same function.
