Abstract
A driver of a semiconductor memory device and driving method thereof is disclosed, which relates to a technology for reducing consumption of a leakage current not required for a driver circuit of a semiconductor memory device. The driver of the semiconductor memory device includes a drive controller configured to selectively provide a first voltage and a second voltage, that have different levels in response to a power-down signal, to a first node; an input driver configured to selectively output a voltage received from the first node in response to a decoding signal; and an output driver configured to be driven in response to an output voltage of the input driver.

A driver of a semiconductor memory device comprising:
- a drive controller configured to selectively provide a first voltage and a second voltage, that have different levels in response to a power-down signal, to a first node;
- an input driver configured to selectively output a voltage received from the first node in response to a decoding signal;
- and
- an output driver configured to be driven in response to an output voltage of the input driver.
A method of driving with a semiconductor memory device comprising:
- providing, with a drive controller, a first voltage or a second voltage, that have different levels in response to a power-down signal, to a first node;
- outputting, with an input driver, a voltage received from the first node in response to a decoding signal;
- and
- driving an output driver in response to an output voltage of the input driver.
