摘要： A high-speed double or quadrature data rate interface semiconductor device and a method thereof are provided. A transmitter (e.g., a data transmitting semiconductor device) for high-speed data transmission transmits a first strobe signal and a second strobe signal, which have a phase difference of 90 degrees there-between, a first group (byte of) data, and a second group (byte of) data. The transmitter adjusts the phase of at least one of the first and second strobe signals based on phase-error information fed back from a receiver and then transmits the phase-adjusted strobe signal to the receiver. The receiver receives the first and second strobe signals from the transmitter and receives the first group (byte of) data and the second group (byte of) data using the first and second strobe signals. The receiver does not require a phase-locked loop (PLL) or a delay-locked loop (DLL), thereby decreasing the circuit area and power consumption of the receiver. In addition, since source synchronization is realized using a strobe signal, phase noise can be efficiently removed.

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.
