Abstract
A semiconductor integrated circuit device with a built-in memory circuit group is disclosed, wherein wiring is started from a data terminal position near a data exchange portion of a memory circuit group to reduce the length of a wiring. Accordingly, an operation speed can be improved by the reduction of wiring capacitance and a ratio of unwired wirings can be reduced by reduction of an occupying ratio of wiring channels.
