ABSTRACT OF THE DISCLOSURE Disclosed is a buffer memory control apparatus, in which a translation lookaside buffer for translating a logical address into a real address to make an access to a buffer storage has a logical address storage portion and a real address storage portion to each of which logical address bits are entered at its column. Column identifying address bits for the logical address storage portion partly overlap on column identifying address for a buffer address array for holding a real address to be supplied to the buffer storage, so that the buffer address array, the real address storage portion, and a comparator circuit for comparing the contents held by the buffer address array and the real address storage portion are divided into sections corresponding to the overlapped a part of bits and the sections are suitably combined and arranged as circuits.
