Abstract: A pointer, N, indicates an address in a virtual memory 
space of a demand paged memory including a plurality of 
virtual address pages (page 1 - Page n+1) and a fixed 
number of physical memory pages into which blocks of 
information (B1 - B17) can be written. A back-up memory 
store (40) is provided for containing paged-out memory 
pages. The pointer, N, is advanced along the virtual address 
pages to indicate the next available virtual address page for 
allocation, and newly allocated blocks are located on the 
virtual address page pointed to by said pointer N. Should the 
necessary space for a block allocation not exist on the page 
pointed to by said pointer, N, a page which is most recently 
used and least sparsely utilized is identified from the physical 
pages onto which blocks have been previously written the 
block is allocated on that page. If no space remains on the 
virtual address pages in physical memory for block alloca­
tion, then, a least recently used and most sparsely allocated 
page is identified and paged-out to the back-up store.
