Patent ID: 6982500

Claim:
An integrated circuit comprising: a first circuit block having: a first voltage differentiator to receive an external power supply and to provide a first power supply for the first circuit block; and a first control module, coupled to the first voltage differentiator, to determine the operation mode for the first circuit block, to supply the first power supply to the first circuit block if the circuit block is operating in a normal power mode and to switch off the first power supply if the first circuit block is operating in a standby mode; and a second circuit block having: a second voltage differentiator to receive the external power supply and to provide a second power supply for the second circuit block; and a second control module, coupled to the second voltage differentiator, to determine the operation mode for the second circuit block, to supply the second power supply to the second circuit block if the circuit block is operating in a normal power mode and to switch off the second power supply if the second circuit block is operating in a standby mode.
