An interface circuit, according to the present invention includes a frequency divider which divides a frequency of a base clock to provide frequency-divided clock signals; a first address register which stores an address signal at a timing in which the frequency-divided clock signal is turned to high; a second address register which stores the address signal at a timing in which the clock signal is turned to low; a first data register which stores a data signal at a timing in which the clock signal is turned to high; and a second data register which stores the data signal at a timing in which the clock signal is turned to low. The data signals stored in the first and second data registers are selectively outputted.
