Random access storage facilities for the CPU of a computer are cascaded in that a facility of relatively fast access speed holds a subset of information held in a facility of lower speed. Memory read requests are applied sequentially to these storage facilities, beginning always with the one of highest access speed, while requests satisfied by a lower speed facilities lead to storage of that information in all facilities of higher access speed. Write requests are made only to one facilities of l...
