ABSTRACT:
In order to improve area efficiency of a mask ROM, a head address is inputted from a common pad (204) only in an initial access, so that addresses are thereafter changed by an internal counter (212). Data output is carried out through the common pad (204). Wires are employed for address input and data output in common, thereby remarkably reducing the number of wires.
