Buffers are arranged in a concentrated manner in a region distant from pads. The region refers to a region in a main region of a semiconductor integrated circuit, except for a central processing unit, a non-volatile memory and a volatile memory. As the buffer requiring a large area is not provided around the pad, a pitch between the pads or a pitch between the pad and an internal circuit (such as the central processing unit) can be made smaller and hence a chip size can be reduced. Therefore, a semiconductor integrated circuit capable of achieving a reduced chip size can be provided.
