  • Reconfigurable power distribution system for three-dimensional integrated circuits
    Patent number: 9665115
    Abstract: A three-dimensional (3D) integrated circuit (IC) device can include a first die having a first supply line and a second die having a second supply line, a power header, and a voltage selection logic. The power header can be connected to the first die and the second die and configured to generate a first voltage on a first voltage line and a second voltage on a second voltage line. The voltage selection logic can be connected to the first supply line and the second supply line and configured to select between the first voltage line and the second voltage line for each of the first supply line and the second supply line.
