Abstract
A circuit for supplying power to a sense amplifier in a semiconductor memory apparatus includes: a compensation controlling unit configured to generate a compensation control signal to determine power compensation, in response to a refresh signal. A power compensating unit supplies a compensation voltage input node, which is applied with a first voltage, with a second voltage in response to the compensation control signal. And, a power supply unit configured to supply the second voltage or a voltage at the compensation voltage input node to a sense-amp driver in response to a first power control signal or a second power control signal.
