bit plane

<graphics> (Or "bitplane") The memory in a graphic display device which holds a complete one-bit-per-pixel image. Several bit planes may be used in conjunction to give more bits per pixel or to overlay several images or mask one with another.

"Bit plane" may be used as a synonym for "bitmap", though the latter suggests the data itself rather than the memory and also suggests a graphics file format.
