The

, a unit of digital information storage, prefixed by the standards-based multiplier mebi (symbol

meaning 2

This unit is most useful for measuring RAM and ROM

chip capacity.

The mebibit is closely related to the megabit

which equals 10

Throughout the 1980s and 1990s, video game manufacturers would sometimes report the amount of internal cartridge ROM

(in megabits) on their packaging. 1 megabit equaled 128 kibibyte

; 8 megabits were 1 mebibyte

of ROM containing game instructions and data.
