Semiconductor device with a sense amplifier unit responsive to a voltage change of input signals and a sense control signal

摘要

A sense amplifier circuit includes an enable signal generation unit configured to generate an enable signal when a change in a voltage level of input signals is sensed; a sink unit configured to provide a sense voltage in response to the enable signal; and a sense unit configured to generate an output signal in response to the sense voltage and the input signals.
