Abstract:
1. An integrated circuit comprising: a plurality of functional blocks, each of the functional blocks being coupled between a first power supply line and a second power supply line, a first functional block being coupled to the first power supply line via a first conductive path including a first switch and a second functional block being coupled to the first power supply line via a second conductive path including a second switch, the first switch and the second switch being arranged to respectively disconnect the first functional block and the second functional block from the first power supply line for switching said functional blocks from an active mode to a standby mode; and a further switch having a first terminal coupled to a node of the first conductive path between the first switch and the first functional block and a second terminal coupled to a node of the second conductive path between the second switch and the second functional block, the further switch having a control terminal that is responsive to an enable signal from a controller.
