Abstract
Provided is concerned with a voltage regulation circuit and method of regulating the voltage, including a reference voltage generator for generating a reference voltage by dividing a core voltage of a semiconductor memory device, a controller for controlling the reference voltage generator to adjust the reference voltage without handling the core voltage in response to a test signal of a test mode, and a voltage generator for generating a bit-line precharging voltage and/or a cell plate voltage in accordance with the reference voltage.
