This voltage island structure for LSI die with peripheral I/Os can resolve three problems as shown below. With this growable structure, users can place as many I/O cells with different Vdd as they want depending on users application requirements. 1. Users can put core-logic of different Vdds in the voltage islands on the same die. 2. Users can turn on/off each growable voltage island independently for power management 3. Users can place I/O cells with different Vdd voltage at any die-sides of the growable voltage islands
