    摘要: An IC device to be newly developed has at least one first function block (11A-11C, 12A, 12B, 14) and at least one second function block (13A, 13B) in which the first and second function blocks of the to-be-newly developed IC device is formed in a single semiconductor substrate, and logic design data of the first function block is available and that of the second function block needs to be newly prepared at a start of fabrication of the IC device. The IC device is, in one embodiment of the present invention, fabricated by starting logic design (53) of the second function block to prepare logic design data of the second function block while doped layers are formed (55) in a semiconductor substrate for the first and second function blocks to provide a semi-completed IC chip, performing (57) mask design of wiring conductor pattern using the logic design data of the first function block and later obtained logic design data of said second function block to prepare mask design data for the IC device, and forming (57) conductor pattern using the mask design data on the semi-completed IC chip to complete a newly developed IC device.

    摘要: A single chip microcomputer comprises a control circuit (12a, 12b), a processing circuit (13a, 13b) and a plurality of ad­dress register - status register pairs. A logical unit formed within the control circuit (12a, 12b) comprises an electrical­ly writable non-volatile semiconductor memory device. Informa­tion can be externally written into the non-volatile semicon­ductor memory included in the logical unit, and the plurality of address register - status register pairs can be arbitrarily selected. As a result, logic function of the logical unit can be arbitrarily established in accordance with externally sup­plied information. Demanded specifications of various users can be satisfied by the logic function thus arbitrarily formed.
