ABSTRACT:
In a named-data hierarchical memory system wherein data is stored in pages at each memory level, a word valid bit to indicate the presence of data and a word modified bit is appended to each data word and associated detection and control apparatus is provided to permit the page oriented data to be stored and fetched on a word basis at each memory level. The detection and control logic functions to store only the data words in a page which contain actual data and to operate each level as a storage queue for the next lower level thereby eliminating the requirement and associated time delay of prefetching a page from the lower level before storage of any data words therein at the higher level.
