ABSTRACT:
A semiconductor integrated circuit device is comprised a main memory portion constructed with memory cells arranged in a plurality of rows and in a plurality of columns, a sub memory portion constructed with a plurality of memory cells arranged in a plurality of rows and in a plurality of columns and a bi-directional data transfer circuit for connecting the main memory portion and the sub memory portion through data transfer bus lines, respectively, wherein the data transfer bus lines in a memory cell area of the main memory portion are arranged in parallel to bit lines in a column direction and connected to the bit lines through a column selection circuit. Therefore, the semiconductor integrated circuit device of the present invention has a main memory suitable for being accessed from a plurality of data processors.
