ABSTRACT:
A semiconductor integrated circuit device comprising a one-chip microcomputer having a nonvolatile memory circuit to and from which write and read operations are carried out at high speed in keeping with the cycle time of the processor. Part of the memory circuit is set aside as a read-only area for accommodating a data processing program, and the rest of the memory is used to write and read data thereto and therefrom. With no need to optimize the assignments of the ROM and RAM parts in the memory circuit, the one-chip microchip is easy to design and manufacture with high productivity. With the program storage area established as desired, users enjoy more convenience use of the one-chip microcomputer than before.
