Noun
tilemap (plural tilemaps)
(computer graphics) A two-dimensional grid made up of rectangular tiles of equal size, each of which can display an image.
Instead, it has a single non-scrolling tilemap layer called the fix layer, while any scrolling layers rely exclusively on drawing sprites to create the scrolling backgrounds (like the Sega Y Board ). Source: Internet
Unlike most other video game consoles of its time, the Neo Geo does not use scrolling tilemap background layers. Source: Internet
