Semiconductor integrated circuit device

摘要

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 ( 10 ), a second memory controller ( 16 ) is provided outside a hard macro ( 12 ) containing a first memory controller ( 15 ). The length of a wiring (second wiring) between the second memory controller ( 16 ) and an IO pad unit ( 13 ) is set shorter than the length of a wiring (first wiring) between the first memory controller ( 15 ) and the IO pad unit ( 13 ). Further, a wiring ( 40 ) is provided which transmits a switch signal for exclusively switching the states of the first memory controller ( 15 ) and the second memory controller ( 16 ) to either one of valid and invalid states.
