Abstract: The disclosure relates to a memory mapping system wherein information is stored on a page by page basis in memory in discontiguous locations therein with the address of the next page in which storage is to take place always being available in the controller to minimize delay in storage from the end of one page to the beginning of the following page, regardless of page location in memory. When a user makes a request for storage space in memory, the amount of memory required is determined and the host looks to see where it can obtain that memory. Typically, use of discontiguous memory locations is required. All of the information relative to the addresses of the discontiguous storage locations in memory is provided to the controller by the host computer in a single command rather than after each move to a discontiguous storage location. All jumps to discontiguous storage locations are then performed independent of the host computer.
