Memory card including reset control unit and reset control method thereof

A memory card having a reset control unit and a reset control method thereof are provided to control multi interface operations so as to have no effect on the other interface, which is normally operated, when a reset signal is inputted. An interface unit(210) includes first and second interfaces and communicates with a host(100) through the first and second interfaces(211,212). A controller(220) includes first and second function blocks(221,222) each corresponding to the first and second interfaces. A reset control unit(240) receives a reset signal, for initializing the first function block, from the host through the first interface and initializes the first function block. The reset control unit decides initialization of the second function block according to communication of the second interface.
