ABSTRACT:
Disclosed is a semiconductor integrated circuit wherein a logic circuit for exchanging signals with RAMS, with the RAMS being disposed centrally on the semiconductor chip or substrate, is divided into a plurality of logic circuits in accordance with the kind of signals and the divided logic circuits are disposed around the RAM in such a manner as to minimize the distance of signal transmission paths with the RAM and in order to attain high speed access to RAMS.
