ABSTRACT:
An AND type read-only memory (D-A-ROM), includes a memory unit divided into blocks in a row direction and into sub-blocks a column direction, a Y decoder, an X decoder and a column selector. An output of the Y decoder and an output of the X decoder are connected to the memory blocks by first and second gate electrode connectors, respectively. A read control signal from the CPU is connected to each of the memory blocks by third gate electrode connectors. In addition, the output of the X decoder is supplied in parallel to each of the memory sub-blocks through bypass connectors including aluminum interconnections of a separately formed second layer. The read control signal is supplied in parallel to each of the memory sub-blocks through bypass interconnections of the second layer.
