Abstract
Disclosed are a high voltage switch circuit and a semiconductor memory device including the same. The high voltage switching circuit includes: a control signal generating circuit configured to supply a supply voltage to an internal node and generate a control signal in response to a first enable signal; a well bias generating circuit configured to apply a well bias to a well of a transistor included in the control signal generating circuit in response to a second enable signal; and a switching circuit configured to switch an input voltage to an output voltage in response to the control signal.
