Abstract
The present invention provides a semiconductor integrated circuit device easy to design timing to be provided with respect to an external memory. In the semiconductor integrated circuit device (), a second memory controller () is provided outside a hard macro () containing a first memory controller (). The length of a wiring (second wiring) between the second memory controller () and an IO pad unit () is set shorter than the length of a wiring (first wiring) between the first memory controller () and the IO pad unit (). Further, a wiring () is provided which transmits a switch signal for exclusively switching the states of the first memory controller () and the second memory controller () to either one of valid and invalid states.
