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:
“‘Tis of the essence of life here,
Though we choose greatly, still to lack
The lasting memory at all clear,
That life has for us on the wrack
Nothing but what we somehow chose;
Thus are we wholly stripped of pride
In the pain that has but one close,
Bearing it crushed and mystified.”
—Robert Frost (1874–1963)
