The first computer to support paging was the supercomputer Atlas, jointly developed by Ferranti, the University of Manchester and Plessey in 1963. The machine had an associative (content-addressable) memory with one entry for each 512 word page. The Supervisor handled non-equivalence interruptions and managed the transfer of pages between core and drum in order to provide a one-level store to programs. WebMay 17, 2024 · Open Settings.
