ABSTRACT:
A method and circuit configuration for digitizing data and control signals using an input buffer in a dynamic random access memory (DRAM) device. In one embodiment, the input buffer includes buffer modules having a differential amplifier with a first input responsive to an input signal and a second input responsive to a reference voltage, a common source stage, and an output stage and a source of a bias voltage controlling impedance of the common source stage, wherein the reference voltage defines the amplitude of the bias voltage.
