Abstract: A method of performing multiple data bus inversion (DBI) and a memory device performing the method are provided. The multiple DBI includes first through third DBI operations, wherein the first DBI operation determines whether to perform data inversion on a first data inversion group in which M×N data bits of a M×N data bit structure are grouped and performs the data inversion on the first data inversion group, the second DBI operation determines whether to perform data inversion on second data inversion groups formed by grouping M data bits from among the M×N data bits and performs the data inversion on the second data inversion groups, and the third DBI operation determines whether to perform data inversion on third data inversion groups formed by grouping N data bits from among the M×N data bits and performs the data inversion on the third data inversion groups.
