This unit is most useful for measuring RAM and ROM chip capacity.
The mebibit is closely related to the megabit which equals 106 bits = 1,000,000 bits.
Throughout the 1980s and 1990s, video game manufacturers sometimes reported the amount of internal cartridge read-only memory (ROM) on packaging in megabits, where 1 megabit equaled 128 kibibyte and 8 megabits were 1 mebibyte of ROM, containing game instructions and data.
