A mebibit (a contraction of mega binary bit) is a unit of information or computer storage, 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 computer technology slang. Throughout the 1980s and 1990s, video game manufacturers would sometimes boast the amount of internal cartridge RAM (in “megabits”) on their packaging, as a selling point. One “megabit” would equate to 128 KiB, whereas 8 “megabits” would equal one mebibyte of RAM in which the console's computer could perform the necessary instructions.
