Abstract
According to an aspect, a data inversion circuit configured to perform DBI-AC encoding using a PAM 4 signal may comprise a data generation unit configured to generate input data based on the PAM 4 signal, a channel comprising N data lines, a first auxiliary signal generation unit configured to generate a first auxiliary signal that determines whether to perform a first encoding on the input data based on the number of each of a plurality of data symbols included in the input data, a first data encoding unit configured to generate intermediate data by performing the first encoding on the input data based on the first auxiliary signal, a second auxiliary signal generation unit configured to generate a second auxiliary signal that determines whether to perform a third encoding on the intermediate data by analyzing the relationship between a plurality of data symbols at a current time point and a plurality of data symbols at a previous time point included in the intermediate data and a second data encoding unit configured to generate encoded data by performing the third encoding on the intermediate data based on the second auxiliary signal, and to transmit the generated encoded data to a data reception unit via the channel and the first auxiliary signal and the second auxiliary signal may be combined into one signal and implemented as a PAM 4 signal.
