Abstract
A physical memory location among multiple programs is shared among multiple programs. In one embodiment, multiple memory units are scanned to detect duplicated contents in the memory units. The memory units are used by programs running on a computer system. A data structure is used to identify memory units of identical contents. To improve performance, an additional data structure can be used to identify memory units of identical contents. Memory units that are identified to have identical contents can share the same physical memory space.
