Abstract
A system and method for memory sharing among computer programs is disclosed. A method for memory sharing among computer programs includes identifying memory units of a plurality of memory units having identical contents, collapsing the identified memory units into a single merged memory page, and mapping the single merged memory page into an associated shared physical memory location. The method further includes when a request to write to a memory unit merged into the single merged memory page is received: copying, by a computer system, contents in the associated shared physical memory location to a different memory location, and redirecting, by the computer system, the request to the different memory location.
