SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE

PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device for increasing a memory region to be used as a general-purpose memory region by a CPU by utilizing a memory region in a functional macro, and for minimizing the increase of a chip size without increasing the capacity of the general-purpose memory, and for coping with the increase request of the general-purpose memory capacity. SOLUTION: The address of a memory region in an unused functional macro among functional macros 13 to 15 is changed by an in-functional macro memory region rearrangement control circuit 17, and the memory region in the unused functional macro is rearranged in a memory region accessible as an RAM region to be used in a general purpose manner by a CPU 11.
