Input buffer for semiconductor memory device and flash memory device including the same

摘要

An input buffer includes an amplifier circuit configured to amplify an input signal and output an amplified signal to a first output node. The input signal is amplified according to a first bias voltage set, at a bias node, to a first level based on a power supply voltage and a reference voltage. The input buffer includes an output circuit configured to receive and buffer the amplified signal and output an output signal to a second output node. The input buffer includes a dynamic bias voltage generator configured to change the first bias voltage to a second level in response to a transition of the output signal.
