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:
“Computers are good at swift, accurate computation and at storing great masses of information. The brain, on the other hand, is not as efficient a number cruncher and its memory is often highly fallible; a basic inexactness is built into its design. The brain’s strong point is its flexibility. It is unsurpassed at making shrewd guesses and at grasping the total meaning of information presented to it.”
—Jeremy Campbell (b. 1931)
