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:
“There are no stars to-night
But those of memory.
Yet how much room for memory there is
In the loose girdle of soft rain.”
