Abstract
The storage control system translates a logical address into a real address by using a translation lookaside buffer (TLB), and checks if a data to be referred to is present in a buffer storage by using a buffer address array (BAA). An integrated logic-in memory device for the storage control system includes a first memory for holding a real address part of the TLB, a second memory for holding a real address part of the BAA, and comparator means, for comparing outputs from the first and second memories, thus eliminating the transfer of a real address from the TLB to the BAA as in a discrete circuit form.
