Abstract
An address conversion system comprises an improved associative memory circuit for providing a real address corresponding to an applied virtual address with reference to the correspondence between virtual and real addresses stored in a main memory. The associative memory includes first and second memories for storing a part of the correspondence between virtual and real addresses. The second memory is essentially a set associative memory but is not connected with address comparators directly. The first memory is higher in speed but smaller in capacity than the second memory. When the first memory stores the correspondence between the virtual and real address corresponding to the applied virtual address, the real address corresponding to the applied virtual address is immediately delivered.
