    摘要: A data bus inversion (DBI) circuit includes at least one DBI block configured to invert an input data signal based on the logic state of input data bits. The DBI block includes a comparison deciding unit configured to generate, in a first mode, a comparison signal based on the number of changed bits by comparing respective bit signals of the input data signal and a previous input data signal. The comparison deciding unit generates an inversion control signal which controls whether the input data will be inverted or not. In a second mode, the comparison deciding unit generates an inversion control signal based on the predominant logic state of the input data signal bits. A data converting unit is configured to invert the input data signal in response to the inversion control signal. Method embodiments are also disclosed.

    摘要: A semiconductor memory device includes a latency controller which provides a power-saving effect. The latency controller includes a first-in first-out (FIFO) register. After a read command is applied, when a precharge command or power-down command is applied, the latency controller outputs a latency signal corresponding to the applied read command and blocks application of sampling and transmission clock signals to the FIFO register.
