摘要： A data communication device or system includes a preamble unit and a data interface. The preamble unit generates or detects a first preamble having a first length for a first data line, and generates or detects a second preamble having a second length for a second data line. The first length is different from the second length, and data on the first and second data lines form parallel data. The data interface communicates a first data with the first preamble via the first data line and communicates a second data with the second preamble via the second data line. The respective length and/or respective pattern of each preamble are adjustable and/or programmable.

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： Integrated circuit memory devices include an internal command generator and a memory control circuit responsive to an internal command generated by the internal command generator. The internal command generator is configured to generate an internal command in response to a combination of an independent command and at least one dependent command received in sequence by the memory device. For example, the internal command generator may be configured to require the independent command to follow the at least one dependent command in the sequence when generating the internal command from the combination of the independent and dependent commands. Alternatively, the internal command generator may be configured to require the independent command to precede the at least one dependent command in the sequence before generating the internal command from the combination of the independent and dependent commands. These independent and dependent commands may be received by the memory device as respective multi-bit external command signals.
