Abstract
The present invention provides an integrated circuit chip which includes a processor; a contact pad unit connected to a host through a plurality of contact pads; a host interface detector including at least one pull-up resistor and one pull-down resistor, for selectively connecting the pull-up resistor and the pull-down resistor to the contact pad unit to detect a host interface status; and an interface unit including a plurality of interface protocols, for communicating with the host using a part or all of the plurality of contact pads, wherein the processor receives a status of the host from the host interface detector, identifies a protocol of the host based on the received status of the host, and controls the interface unit so as to enable an interface protocol that is used to communicate with the host.
