Abstract: A virtual memory system comprising a main storage and a smaller high speed buffer. Both main storage and the buffer are real-address-oriented. Current virtual-to-real address translations are retained in a Translation Look Aside Table (TLAT) and real addresses of data stored in the buffer are maintained in a buffer directory. The CPU-provided virtual address causes access to the TLAT and to the buffer directory. The virtual address stored in the word accessed from the TLAT is compared to the virtual address from the CPU and the real addresses accessed from the TLAT and the buffer directory are compared to each other. If both comparisons are equal, the data is accessed from the buffer.
