The management of a multi-level non-paged memory system
Forest Baskett, J. C. Browne, William M. Raike · 1970
There is a clear tendency for large-scale and, especially time-sharing computer systems to have several levels of random access memory with gradations in access time, degree of addressability, and functional capability. In our configuration at The University of Texas at Austin these are a high-speed magnetic core memory, an extended core memory of magnitude 4 times the size of the main memory, and 4 large, fast disks. An extensive literature has already developed on the management of multi-level systems where the main memory is structured in pages, usually with an extended logical addressing space.
