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:
“A man at work, making something which he feels will exist because he is working at it and wills it, is exercising the energies of his mind and soul as well as of his body. Memory and imagination help him as he works. Not only his own thoughts, but the thoughts of the men of past ages guide his hands; and, as part of the human race, he creates. If we work thus we shall be men, and our days will be happy and eventful.”
—William Morris (1834–1896)
