x86 memory segmentation refers to the implementation of memory segmentation on the x86 architecture. Certain portions of the memory may be addressed by a single index register without changing a 16-bit segment selector. In real mode or V86 mode, a segment is always 65,536 bytes in size (using 16-bit offsets). In protected mode, a segment can have variable length. Segments can overlap.

Famous quotes containing the word memory:
“In excited conversation we have glimpses of the universe, hints of power native to the soul, far-darting lights and shadows of an Andes landscape, such as we can hardly attain in lone meditation. Here are oracles sometimes profusely given, to which the memory goes back in barren hours.”
—Ralph Waldo Emerson (1803–1882)
