Summary: | A data bus inversion (DBI) circuit of a memory device includes a first processing component configured to generate first combination data by combining read data read from a memory cell region and previous data previously outputted from a data line, and generate second combination data by selectively inverting the first combination data depending on a result of comparing the first combination data and the previous data; and a second processing component configured to generate data to be outputted from the data line, by combining the second combination data and the previous data, wherein the second processing component generates bits of unnecessary bit positions in the data to be the same as bits of the unnecessary bit positions in the previous data. |
