Voltage regulator for providing word line voltage

A voltage regulator for providing a word line voltage, comprising:

• a voltage divider, coupled between the word line voltage and a low reference voltage, comprising a plurality of resistive elements connected in series on a plurality of intermediate nodes;
• a comparator, connected to a divided intermediate node among the plurality of intermediate nodes, configured to provide an enable signal according to a divided voltage value on the divided intermediate node;
• a boost circuit, coupled to the comparator, configured to boost the word line voltage in response to the enable signal;
• and
• a bypass transistor, wherein a source terminal of the bypass transistor is connected to a first intermediate node among the plurality of intermediate nodes, a drain terminal of the bypass transistor is connected to a second intermediate node among the plurality of intermediate nodes, and a gate terminal of the bypass transistor receives a control signal,
• wherein the bypass transistor is turned-off in response to the control signal having an intermediate voltage value on the first intermediate node.
