ABSTRACT:
An integrated circuit ROM comprises a memory cell matrix having a plurality of pairs of output lines, and plurality of pairs of external terminals. An output selection circuit is connected between the output lines and the external terminals and adapted to connect the output lines to the corresponding external terminals in a first mode and to alternatively connect output lines of each output line group to one predetermined external terminal of the corresponding external terminal group in a second mode. A control circuit is connected to at least one given external terminal which is disconnected from the corresponding output line when the output selecting circuit is in the second mode. This control circuit is in response to an address signal from the given external terminal to control the output selection circuit so as to cause it to selectively connect one output line of each output line group to the above predetermined external terminal of the corresponding external terminal group. Further, a mode selection circuit is associated to the output selection circuit and has a circuit structure fixed by a selected code mask so as to put the output selection circuit in a predetermined one of the first and second modes.
