PURPOSE: To provide a large capacity multi-port cache memory the area of which is drastically reduced in comparison with conventional ones. CONSTITUTION: The conventional multi-port cache memory is excellent in high speed since it is constituted by using multi-port cell blocks, however, chip size is increased when erroneous cache is attempted to be reduced by increasing its capacity since the areas of the cell blocks to be components increase in proportion to square of the number of ports, which becomes a cause of cost increase. The large capacity multi-port cache memory having random access band width, to which parallel access from plural ports are enabled and suitable for use for the most advanced microprocessor with low probability of the erroneous cache is easily provided since the multi-port cache memory is formed by using one port cell block suitable for capacity increase as the component.
