System memory beyond 1 megabyte in computers based on the Intel 80x86 processors. This memory is accessible only when an 80386 or higher-level processor is operating in protected mode or in emulation on the 80286. To use extended memory, MS-DOS programs need the aid of software that temporarily places the processor into protected mode or by the use of features in the 80386 or higher-level processors to remap portions of extended memory into conventional memory. Extended memory is not an issue in Windows 9x, all versions of Windows NT, Windows 2000, and Windows XP. See also EMS, extended memory specification, protected mode.
