HSIC COMMUNICATION SYSTEM AND METHOD

A High Speed Inter Chip (HSIC) system and method for minimizing power consumption by controlling the state of the HSIC module through a control line are provided. The method between a host and a slave includes transitioning, when no communication request exists for a first reference time in an active state where all functions of the HSIC modules are enabled, to a suspend state where least functions used for maintaining a communication link of the HSIC modules and transitioning, when no communication request exists for a second reference time in the suspend state, to a power-off state where the HSIC modules turn off. The HSIC communication method and apparatus are advantageous to minimize the electric current consumption of the HSIC consumption system.
