Abstract
Aspects of the disclosure provide an integrated circuit (IC) chip. The IC chip includes core circuits having an operational mode and a power saving mode, and at least a pad module. The pad module includes a pad, a switchable pull-up module configured to pull up a voltage on the pad when the switchable pull-up module is switched on, a switchable pull-down module configured to pull down the voltage on the pad when the switchable pull-down module is switched on, and a control module configured to control the switchable pull-up module and the switchable pull-down module according to a detection of the voltage on the pad when the core circuits enter the power saving mode.
