The circuit layer includes first and second activation devices connected to the energy delivery device, the first and second activation devices to activate the energy delivery device, first drive logic coupled to the first activation device, and second drive logic coupled to the second activation device. An interconnect layer couples a same address selection signal to the first drive logic and the second drive logic.
