Abstract
A segmented bus architecture (800) removes certain ESD circuitry from each I/O pad cell (806, 812) and places it in a power pad cell (808, 814) or in some other unused area of the integrated circuit which incorporates the SBA. The removed ESD circuit is shared by several adjacent I/O pad cells via a segmented ESD bus. As a result, each individual I/O pad cell may be reduced in size.
