  • Computer segmented memory management technique wherein two expandable memory portions are contained within a single segment
    Patent number: 4445170
    Abstract: Separate memory management units are described for use with a central processing unit to separately control expanding stack and data memory portions within a single logical memory segment. The stack and data portions are prevented from expanding into each other by a break register which contains an address between the two memory portions and is updated as the stack and data memory portions expand and contract. The stack memory management unit only is enabled when a portion of the memory is addressed on one side of the break value while the data memory management unit only is utilized when the address is on the other side of the break value.
