摘要： Semiconductor devices, a system including said semiconductor devices and methods thereof are provided. An example semiconductor device may receive data scheduled for transmission, scramble an order of bits within the received data, the scrambled order arranged in accordance with a given pseudo-random sequence. The received data may be balanced such that a difference between a first number of the bits within the received data equal to a first logic level and a second number of bits within the received data equal to a second logic level is below a threshold. The balanced and scrambled received data may then be transmitted. The example semiconductor device may perform the scrambling and balancing operations in any order. Likewise, on a receiving end, another semiconductor device may decode the original data by unscrambling and unbalancing the transmitted data. The unscrambling and unbalancing operations may be performed in an order based upon the order in which the transmitted data is scrambled and balanced.

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： An output circuit of a semiconductor memory device includes a first data path, a second data path and a third data path. The first data path transfers a sense output signal, and latches the sense output signal to output the sense output signal to a first node. The second data path transfers the sense output signal, and latches the sense output signal to output the sense output signal to the first node. The third data path latches a signal of the first node, and transfers the signal of the first node to generate output data. Accordingly, the semiconductor memory device including the output circuit can operate at a relatively higher frequency using a pseudo-pipeline structured circuit, which combines a wave pipeline structure with a full pipeline structure.
