The mebibit is a standards-based binary multiple (see prefix mebi) of the bit, a unit of digital information storage. It is abbreviated Mibit or sometimes Mib.
This unit is most useful for measuring RAM and ROM chip capacity.
The mebibit is closely related to the megabit which equals to 106 bits = 1,000,000 bits, but sometimes used to denote the mebibit value in traditional computer technology writing. 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.
