A memory management system for a digital computer divides a virtual memory space into regions. Each region has attributes indicating generation, volatility, and activity. During garbage collection, memory objects referenced by normal program execution are copied to regions having an active attribute. Objects copied as a result of garbage collector scavenger action are moved to regions which are inactive. Increasing levels of inactivity are provided in different regions. Grouping of active objects into active regions causes a large proportion of main memory to contain only active objects, which minimizes paging and increases system performance.
