    摘要: Provided are a circuit and method for sampling a valid command using a valid address window extended for a high-speed operation in a double pumped address scheme memory device. A method for extending the valid address window includes: inputting a valid command signal and a first address signal at the first cycle of a clock signal; inputting a second address signal at the second cycle of the clock signal; generating a decoded command signal and extended first and second internal address signals respectively in response to the command signal and the address signals; and latching and decoding the extended first and second internal address signals in response to the decoded command signal.

The semiconductor device includes a control code generation unit generating a control code in response to a control signal, an addition unit adding an adjustment code to the control code to produce an adjusted control code, and an ODT circuit, wherein an impedance of the ODT circuit is adjusted in response to the adjusted control code. The semiconductor device can adjust the control code more precisely by adding or subtracting the adjustment code to or from the control code. Accordingly, the impedance of an OCD circuit or ODT circuit can be adjusted more precisely.

    摘要: We describe an input buffer having a stabilized operating point and an associated method. 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.
