ABSTRACT:
A semiconductor integrated circuit device includes a main memory portion and a sub memory portion including a plurality of memory cell groups, wherein a bi-directional data transfer is performed between an arbitrary area of the main memory portion and each of the plurality of the memory cell groups and the plurality of the memory cell groups function as independent cache memories, respectively. Therefore, the semiconductor integrated circuit device of the present invention has a main memory suitable for being accessed from a plurality of data processors.
