Abstract
The present technology relates to an electronic device. A driver for generating a signal that satisfies a characteristic required according to a type of a signal includes a current controller configured to control total current flowing through the driver based on a selected signal, among a plurality of signals, applied to a page buffer that stores data, a load controller configured to control a magnitude of a load of an output terminal of the driver based on the selected signal and a cap compensator configured to control the magnitude of the load of the output terminal by increasing or decreasing a capacitance of the load of the output terminal based on the selected signal.
Claims20
A driver comprising:
- a current controller configured to control total current flowing through the driver based on a selected signal, among a plurality of signals, applied to a page buffer that stores data;
- a load controller configured to control a magnitude of a load of an output terminal of the driver based on the selected signal;
- and
- a cap compensator configured to control the magnitude of the load of the output terminal by adjusting a capacitance of the load of the output terminal based on the selected signal.
A method of operating a driver, the method comprising:
- determining a selected signal, among a plurality of signals, to be applied to a page buffer that stores data;
- controlling a total current flowing through the driver based on the selected signal;
- controlling a magnitude of a load of an output terminal of the driver based on the selected signal;
- and
- controlling the magnitude of the load of the output terminal by adjusting a capacitance of the load of the output terminal based on the selected signal.
A memory device including a page buffer that stores data, the memory device comprising:
- a multiplexer configured to, based on an enable signal, output a voltage signal from among a plurality of voltage signals;
- a driver configured to control total current flowing through the driver and a magnitude of a load of an output terminal of the driver based on the voltage signal output from the multiplexer;
- and
- a control signal generator configured to generate a signal to be applied to the page buffer based on a drive input signal output from the output terminal of the driver.
