    摘要: A semiconductor memory device includes a plurality of banks. A data path may be divided into a read data path and a write data path, therefore, parallel processing of write and read commands are possible. The semiconductor memory device may include an address bank buffer, address buffer, column predecoder and/or a decoder. The semiconductor memory device may begin execution of a write command in a bank in one clock cycle and begin execution of a read command in the following clock cycle, therefore, bus efficiency is increased and/or write-to-read turn around time is reduced.

    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.

An input buffer may include a first differential amplifying unit to generate a first output signal having a first operating point and a second differential amplifying unit to generate a second output signal having a second operating point. An output control circuit varies respective weights of the first and second output signals responsive to an output control signal. The first differential amplifying unit may operate responsive to a reference voltage and an input voltage signal. The second differential amplifying unit may operate responsive to the reference voltage and the input voltage signal. The first operating point may be relatively higher than the second operating point.
